==General description==<br />
<br />
The Wachau valley is one of the two places in Austria where the Donau can flow freely. The landscape is a mix of fluvial nature, arid grasslands, grassy slopes, wine terraces and fruit orchards. In 2000 the Wachau valley was granted UNESCO World Heritage status and is part of the Natura2000 network. The project LIFE Nature Wachau was implemented to further improve the Wachau valley by structuring the main channel with gravel banks, linking old Danube tributaries back to the main river, management of dry grasslands and grassy slopes, improvement of semi-natural forests and the creation of a nature protection coordination body for the Wachau valley. Location Aggsbach is located close to Aggsbach Dorf. <br />
<br />
<br />
==Pressures and Drivers==<br />
<br />
Regulation of the Danube for 100 years has created embankments to protect the villages and agricultural lands in the floodplain. The combination of power stations, river bed erosion and migration obstacles have accelerated the siltation of the tributaries of Aggsbach, cutting off the tributary from the Danube which created dead traps for fish. This had a devastating effect on the population of Common Nase (Chondrostoma nasus) from over 100,000 several decades ago to 3000-7000 in 2002.<br />
<br />
<br />
==Global objectives==<br />
<br />
The global objective was to link the old tributary to the Danube to create refuge habitat for riverine species.<br />
<br />

<br />
<br />
==Measures selection==<br />
<br />
In the Aggsbach, 80,000 m3 of fine material was removed to reconnect the silted up tributary with the Donau. The material was used to create a fled embankment atop of the old rubble. At the inflow, a bridge had to be built to ensure the passability of the Donau cycle way. <br />
<br />
<br />
==Monitoring==<br />
<br />
No pre- or post-restoration monitoring plans for this project could be found. Results in the Laymans report do show that fish, birds, amphibians and dragon flies were surveyed, but it is not clear if this was part of a large monitoring scheme planned in the program or regular monitoring at the site outside of the project.<br />
<br />
<br />
==Expectations and Response==<br />
<br />
It was expected that the new tributary would be a refuse for rare and endangered species. <br />
<br />
The results show that the tributary is a good spawning ground for fish, with 22 new fish species identified including Ide ((Leuciscus idus) and Pike (Esox lucius). <br />
<br />
<br />
==Cooperation==<br />
<br />
The project leader of the Rührsdorf-Rossatz was Via Donau – Österreichische Wasserstraßen-Gesellschaft mbH. Other project partners were:<br />
<br />
* Land government of lower Austria<br />
* Lower Austrian Fishery Association<br />
* Federal Ministry of Agriculture and Forestry, the Environment and Water Management<br />
* Arbeitskreis Wachau: Regionalentwicklung<br />
* HYDRO INGENIEURE Umwelttechnik GmbH<br />
* Ezb Eberstaller Zauner Büros<br />
* Freiwasser, Arbeitsgemeinschaft fur Ökologie, Kulturtechnik und Wasserwirtschaft<br />
<br />
<br />
==Communication==<br />
<br />
Cooperation and approval of the landowners and farmers was important for the project. The project partners worked in collaboration with the market town of Schönbühel-Aggsbach, Walpersdorf estate management and the Austrian fisheries association to ensure everybody affected by the measures approved the project. <br />
<br />
After the project was completed, a documentary was made available for schools and communities for free. A touring exhibition with six large displays traveled across municipal offices and schools. A book, Wachau and its surroundings – habitats of a cultural landscape by Werner Gammerith in association with LIFE Wachau was published and made available in bookstores. Information boards were placed at prominent sites to inform visitors about the natural features. Folders and a regional newspaper ‘landschaften’ have been produced with information about LIFE and the LIFE Wachau project.<br />
<br />
<br />
==Funding==<br />
<br />
The total project costs were € 5,255,000, 50% of which was financed by EU LIFE. The other half was divided between the project partners.<br />

<br />
==Measures selection==<br />
<br />
The old, silted up tributaries of Venedig and Pritzenau were deepened and reconnected to the Danube by two inflow openings. The excavated fine material was reused to cover the rubble on the banks of the Danube creating a new 1 km flat embankment. <br />
<br />
==Monitoring==<br />
<br />
No pre- or post-restoration monitoring plans for this project could be found. Results in the Laymans report do show that fish, birds, amphibians and dragon flies were surveyed, but it is not clear if this was part of a large monitoring scheme planned in the program or regular monitoring at the site outside of the project.<br />

<br />
It was expected that the new tributary would be a refuse for rare and endangered species. <br />
<br />
<br />
The results show that the tributaries have created a natural paradise for people and animals. Fish use the new tributaries for spawning and rest and 35 new species were identified when surveying the channel in 2007, including the endangered Huchen (Hucho hucho), Danube roach (Ratilus virgo), Striped ruffe (Gymnocephalus schraetser), Streber (Zingel streber) and Common Nase (Chondrostoma nasus). Also, several breeding pairs of Common kingfisher (Alcedo atthis) was seen.<br />

==Measures selection==<br />
<br />
The old, silted up tributaries of Venedig and Pritzenau were deepened and reconnected to the Danube by two inflow openings. The excavated fine material was reused to cover the rubble on the banks of the Danube creating a new 1 km flat embankment. <br />
<br />
==Monitoring==<br />
<br />
No pre- or post-restoration monitoring plans for this project could be found. Results in the Laymans report do show that fish, birds, amphibians and dragon flies were surveyed, but it is not clear if this was part of a large monitoring scheme planned in the program or regular monitoring at the site outside of the project.<br />
<br />
<br />
==Expectations and Response==<br />
<br />
It was expected that the new tributary would be a refuse for rare and endangered species. <br />
<br />
<br />
The results show that the tributaries have created a natural paradise for people and animals. Fish use the new tributaries for spawning and rest and 35 new species were identified when surveying the channel in 2007, including the endangered Huchen (Hucho hucho), Danube roach (Ratilus virgo), Striped ruffe (Gymnocephalus schraetser), Streber (Zingel streber) and Common Nase (Chondrostoma nasus). Also, several breeding pairs of Common kingfisher (Alcedo atthis) was seen.<br />
<br />

<br />
==Communication==<br />
<br />
Cooperation and approval of the landowners and farmers was important for the project. The project partners worked in collaboration with the market town of Rossatz-Arnsdorf, the farming community Rossatz and the Austrian fisheries association to ensure the 80 landowners affected by the measures approved the project. <br />
<br />
<br />
After the project was completed, a documentary was made available for schools and communities for free. A touring exhibition with six large displays traveled across municipal offices and schools. A book, Wachau and its surroundings – habitats of a cultural landscape by Werner Gammerith in association with LIFE Wachau was published and made available in bookstores. Information boards were placed at prominent sites to inform visitors about the natural features. Folders and a regional newspaper ‘landschaften’ have been produced with information about LIFE and the LIFE Wachau project.<br />

==General description==<br />
<br />
The Noordwaard is part of the Biesbosch. The Biesbosch has a turbulent history, with many changes by man, water and nature. The area used to be an estuary, but in the Middle Ages it was a large polder for agriculture. The Saint-Elizabeth flood in 1421 turned the polder into a large lake. Later, natural processes developed the Biesbosch again into an estuary. In the 1885, the Nieuwe Merwede was constructed to regulate the discharge in the area and in the 20th century, the entire Biesbosch was again a polder but with large parts of the original creeks remaining. Since the 90s nature development has given parts of the area back to nature and it is now an important nature and recreation area. The influence of the tides was lost with the construction of the Deltaworks, but the Biesbosch still has a high ecological value. The Noordwaard has a large network of creeks caused by the flow dynamics and sediment transport by the tides. <br />
<br />
The Noordwaard was selected to serve as a flood retention area in the Room for the River program, a national program to adapt the current flood defense structure to future climate change. In this project, agricultural land is given back to the river to improve the discharge during flooding and the nature is allowed to develop.<br />
<br />
<br />
==Pressures and Drivers==<br />
<br />
Agriculture has played a large part in the current look of the area. In the past land has been reclaimed and turned into small polders which were later connected. The river lost its connection with the floodplain by the embankments which protect the polders. Now, recreation also puts pressure on the system. The Biesbosch is a popular area for boating and the increasing number of recreationists damage and disturb habitats.<br />
<br />
<br />
==Global objectives==<br />
<br />
The project has two global objectives, namely:<br />
<br />
* Create more intertidal nature that is connected to the existing Natura 2000 area Biesbosch<br />
* Decrease normative high water level at Gorinchem with 30 cm and keep local houses protected<br />
<br />
<br />
==Specific objectives==<br />
<br />
The project only has a specific objective for flood protection. The normative high water level at Gorinchem has to be reduced with 30 cm.<br />
<br />
<br />
==Success Criteria==<br />
<br />
The success criteria is a reduction of the normative high water level at Gorinchem with 30cm<br />
<br />
<br />
==Site description==<br />
<br />
<br />
==Measures selection==<br />
<br />
A map from 1905 is used as reference for the development of the area. The embankments of a large number of polders are lowered to create an area which will flood during winter. Two clusters of small polders remain protected by high embankments. Houses outside the new dike rings will be adapted to flooding. Historical creeks are restored, but in some cases are closed off to prevent recreation. Nature is allowed to develop, but only on the edges of the discharge zone. The rest of the zone remains empty with grasslands that can be used for grazing in summer. Recreation is concentrated in two recreation zones on the west and east side of the area to reduce recreational pressure in the discharge area and the creeks.<br />
<br />
<br />
==Monitoring==<br />
<br />
No information about pre- or post-restoration monitoring could be found in the project documents. <br />
<br />
<br />
==Expectations and Response==<br />
<br />
It is expected that the measures will have a positive effect on the ecological value of the Noordwaard and the Biesbosch as well as improvement of the flood protection. There are more possibilities for recreation, but the concentration of these activities will not disturb the local communities in the polder clusters. Agriculture will lose a large share of land in the Noordwaard from 1750 to 600 ha. To keep the livelihood of farmers sustainable small scale recreational side activities are allowed.<br />
<br />
<br />
==Cooperation==<br />
<br />
Project Ontpoldering Noordwaard is lead by Rijkswaterstaat, in cooperation with:<br />
<br />
* Ministerie van Infrastructuur en Milieu<br />
* Ministerie van Economische Zaken, Landbouw en Innovatie<br />
* Provincie Noord-Brabant<br />
* Waterschap Rivierenland<br />
* Gemeente Werkendam<br />
* Combinatie Noordwaard (group of companies involved in implementation)<br />
<br />
<br />
==Communication==<br />
<br />
During the planning phase, an advisory board with members of all relevant stakeholder groups was set up and the project plans were discussed. The project is currently in the implementation phase. The stakeholders and general public is informed via a website with a contact form, information meetings twice per month, project news letters and a special phone number that can be called when a calamity occurs for direct contact with the contractor (Combinatie Noordwaard). <br />
<br />
<br />
==Funding==<br />
<br />
The exact project budget could not be found in the available documents. The project is part of the Room for the River program which has a budget of 2.180 million Euro.<br />

==General description==<br />
<br />
The Bergsche Maas was constructed in 1904 as part of the plan to cut off the connection between the Meuse and Waal rivers. The Overdiepse Polder is located between the Bergsche Maas and the Oudje Maasje. A large part of the polder is agricultural land. <br />
<br />
The Overdiepse Polder was selected as flood retention area in the Room for the River project, a national project to ensure the current flood protection level is sustained in the future, <br />
This project is very unique, since the local residents were very involved the project in its early stages and presented the solution that will be implemented. Instead of buying out the farmers, the farmers agreed to move their farms on terps, a flood protection measure used in ancient times.<br />
<br />
==Pressures and Drivers==<br />
<br />
The Overdiepse Polder is dominated by agriculture and surrounded by embankments to ensure the polder is protected from the river. This has lead to a loss of connectivity with the floodplain and a poor quality of the remaining nature.<br />
<br />
==Global objectives==<br />
<br />
The project has two global objectives:<br />
<br />
* Create ecological zone along banks Oud Maasje and create new habitat in Overdiepse polder<br />
* Improve water retention capacity in Bergsche Maas<br />
<br />
==Specific objectives==<br />
<br />
The project has no specific objectives for ecology besides compensation of a few protected woodland areas. For flood protection, it is expected that the measures will lower the normative high water level with 27 cm, but no evidence could be found that suggests this is also a specific objective.<br />
<br />
==Success Criteria==<br />
<br />
Since it is unclear if the expectation of a 27cm reduction of the normative high water level is a specific objective, it is not specified as a success criterion. For ecology, no success criteria could be found in the available documentation.<br />
<br />
==Site description==<br />
<br />
<br />
==Measures selection==<br />
<br />
A new dike is constructed along the Oude Maasje. On this dike, 9 terps are constructed for the farmers that remain in the polder. The construction of these terps is unique in the Netherlands. Building an artificial hill to protect the buildings from flooding is a measure used in ancient times (500 -1200 AD) before dike construction was common. All old buildings are then demolished and the old dike is lowered to make flooding of the polder possible when a 25yr flood occurs. One the west site of the polder, soil needed for the new terps is removed, creating a pond that where nature is allowed to develop. In the zone between the new dike and the Oudje Maasje, nature development is encouraged.<br />
<br />
==Monitoring==<br />
<br />
No pre- and post-restoration monitoring plans could be found in the available documentation. It is likely that a habitat survey was preformed during the permit process, but the results could not be found.<br />
<br />
==Expectations and Response==<br />
<br />
It is expected that more river nature will develop in the new ecological zone of the Oude Maasje. The new nature will improve the recreational value of the area. The normative high water level will be lowered with 27cm, significantly improving the flood protection level in the local area. In case there is flooding, it will damage the agricultural lands but the farmers will be compensated when this happens.<br />
<br />
Since the project will be completed in 2016, no response can be described.<br />
<br />
==Cooperation==<br />
<br />
The project Overdiepse Polder is lead by Provincie Noord-Brabant, in cooperation with:<br />
<br />
* Gemeente Geertruidenberg<br />
* Gemeente Waalwijk<br />
* Waterschap Brabantse Delta<br />
* Rijkswaterstaat<br />
* Habiforum<br />
* The Association of residents and businesses<br />
<br />
<br />
==Communication==<br />
<br />
The project is unique because of the large input of the local residents in the decision of the project plan. This high level of participation at the start of the project shows how local residents can present a very creative project plan where they will fully cooperate with the project partners. Instead of endless discussions and resistance, this option is much easier and faster provided that the plans of the local residents are sufficient to reach the goals of the project. Consistent communication via meetings from an early stage is vital for active participation of the stakeholders. <br />
<br />
Communication with the general public is done via a project website, brochures, press releases in local newspapers and radio, excursions and newsletters.<br />
<br />
<br />
==Funding==<br />
<br />
The total cost of this project is 111 million Euro. This will be financed via the Room for the River program which has a budget of 2.180 million Euro<br />

==General description==<br />
<br />
The site Bislich-Vahnum is located between Rhine km 823.50 and 827.00 close to the town of Bislich. The floodplain is part of the protected Natura 2000 site named “Naturschutzgebiet Rheinaue Bislich-Vahnum”. This nature site has RAMSAR and SPA designations due to its variety of river and alluvial habitats. There is still a lack of spawning grounds and breeding habitats for several rheophilic and migratory fish species.<br />
<br />
<br />
==Pressures and Drivers==<br />
<br />
The drivers in the Rhine near Bislich-Vahnum are navigation, flood protection and urbanization. The town of Bislich is situated in the natural floodplain and is protected by a dike that serves as the boundary of the Bislich-Vahnum floodplain. Navigation plays an important role in the current shape of the river. The channel is uniform and fixed to improve navigability of the river and the waves generated by the passing ships damage habitats on the banks of the river. This channelization has deteriorated the dynamics of the river system and their related habitats.<br />
<br />
<br />
==Global objectives==<br />
<br />
The global objective of this restoration project is the creation of a shallow water zone in connection with the Rhine with a discharge gradient while protected from waves from passing ships.<br />
<br />
<br />
==Specific objectives==<br />
<br />
No specific objectives could be found in the available documentation<br />

Map of planned measures in Bislich-Vahnum<br />
<br />
==Measures selection==<br />
<br />
A side channel will be constructed which should have permanent flow. Gravel extraction lakes will be connected to the side channel. An inlet construction will be made to control the flow and to prevent impairments of the main channel. Another inlet construction is made in the Melkstalldamm to connect the upstream half of the side channel with the downstream half. This dam cannot be removed as it serves as the access road to grasslands used by farmers. An unused military road will be relocated to make the connection to the other side of the side channel possible.<br />
<br />
==Monitoring==<br />
<br />
In 2004, a survey of the current biotope types was made as part of the feasibility study. A post-monitoring will be carried out to establish if the goals have been reached and what the impact is on the main course, the other land uses in the forelands and the flood water level. In the individual project phases, the population of selected breeding and resting bird species is counted to follow the development of the population. The development of biotopes and plant communities is followed in a 130ha area. The exact methods of monitoring could not be identified in the available documentation<br />
<br />
==Expectations and Response==<br />
<br />
It is expected that the side channel will improve the local ecology. It will provide flow-dependent habitats which are sensitive to wave damage. The new habitats provide nursery grounds for fish like bullhead, houting and spined loach. It will also be a resting place for many species of wading and water birds. The removal of obstructions in the floodplain will improve the local flood discharge.<br />
<br />
Since the project is finished in 2015, no response can be described.<br />

The channel is uniform and fixed to improve navigability of the river and the waves generated by the passing ships damage habitats on the banks of the river. This channelization has deteriorated the dynamics of the river system and their related habitats.<br />
<br />
<br />
==Global objectives==<br />
<br />
The global objective of this restoration project is the creation of a shallow water zone in connection with the Rhine with a discharge gradient while protected from waves from passing ships.<br />

<br />
==Measures selection==<br />
<br />
A side channel will be constructed which should have permanent flow. Gravel extraction lakes will be connected to the side channel. An inlet construction will be made to control the flow and to prevent impairments of the main channel. Another inlet construction is made in the Melkstalldamm to connect the upstream half of the side channel with the downstream half. This dam cannot be removed as it serves as the access road to grasslands used by farmers. An unused military road will be relocated to make the connection to the other side of the side channel possible.<br />
<br />
==Monitoring==<br />
<br />
In 2004, a survey of the current biotope types was made as part of the feasibility study. A post-monitoring will be carried out to establish if the goals have been reached and what the impact is on the main course, the other land uses in the forelands and the flood water level. In the individual project phases, the population of selected breeding and resting bird species is counted to follow the development of the population. The development of biotopes and plant communities is followed in a 130ha area. The exact methods of monitoring could not be identified in the available documentation<br />
<br />
==Expectations and Response==<br />
<br />
It is expected that the side channel will improve the local ecology. It will provide flow-dependent habitats which are sensitive to wave damage. The new habitats provide nursery grounds for fish like bullhead, houting and spined loach. It will also be a resting place for many species of wading and water birds. The removal of obstructions in the floodplain will improve the local flood discharge.<br />
<br />
Since the project is finished in 2015, no response can be described.<br />

==General description==<br />
<br />
The site Bislich-Vahnum is located between Rhine km 823.50 and 827.00 close to the town of Bislich. The floodplain is part of the protected Natura 2000 site named “Naturschutzgebiet Rheinaue Bislich-Vahnum”. This nature site has RAMSAR and SPA designations due to its variety of river and alluvial habitats. There is still a lack of spawning grounds and breeding habitats for several rheophilic and migratory fish species.<br />
<br />
<br />
==Pressures and Drivers==<br />
<br />
The drivers in the Rhine near Bislich-Vahnum are navigation, flood protection and urbanization. The town of Bislich is situated in the natural floodplain and is protected by a dike that serves as the boundary of the Bislich-Vahnum floodplain. Navigation plays an important role in the current shape of the river. The channel is uniform and fixed to improve navigability of the river and the waves generated by the passing ships damage habitats on the banks of the river. This channelization has deteriorated the dynamics of the river system and their related habitats.<br />

==General description==<br />
<br />
The Drau river is the fourth longest tributary of the Donau with a length of 707 km. The source of the river is in the Italian municipality Toblach where it continues its flow through Austria, Slovenia, Croatia and Hungary. The mouth of the river in the Donau is near the city of Osijek. <br />
<br />
The Upper Drau in Austria is an European protected area with the largest grey alder riparian forests of Austria and over 140 species of birds, including 51 red-listed species. The LIFE project ‘Life vein – Upper Drau River’ was carried out to counteract the trend of too narrow channels that are vulnerable for erosion and flooding by widening the river. Location Amlach/St. Peter is close to the village of Unteramlach and St. Peter, downstream of Spittal an der Drau.<br />
<br />
==Pressures and Drivers==<br />
<br />
The Upper Drau is the last free-flowing, not dammed stretch of the river Drau. Nevertheless, human activity has changed the river and its floodplains. When a rail road line was build through the valley in 1870, regulatory procedures were carried out in order to reduce the flood danger and to expand intensive agricultural lands and settlements. The embankments created a narrow channel which suffered from bed erosion. The river bed deepened and wetlands and agricultural lands went dry with the sinking groundwater level. The stability of bank protection structures also suffered from the erosion.<br />
<br />
==Global objectives==<br />
<br />
The project has 4 global objectives<br />
<br />
* Further stabilization of the Drau river bed through widening and strengthening of bed load influx from tributary brooks.<br />
* More pristine, dynamic shaped river habitats<br />
* Improved information and visitor management on site<br />
* International cooperation with the respective authorities of the Drau neighboring states<br />

<br />
Amlach/St. Peter before (2009) and after completion in 2011. Taken from Life vein – Upper Drau River (2011)<br />
<br />
==Measures selection==<br />
<br />
In Amlach/St. Peter, the river bed was widened with 20 meters by moving 60,000 cubic meters of soil and gravel. New wetlands and water bodies were constructed, as well as a new side channel.<br />
<br />
==Monitoring==<br />
<br />
''Pre-restoration monitoring''<br />
<br />
A pre-restoration monitoring scheme was carried out to assess the current state of the location. The monitoring focuses on:<br />
<br />
* Habitats and animals on the Habitat and Birds Directive<br />
* Fish (presence of species and number of individuals)<br />
* Carabid beetles and other macro-invertebrates (number of species)<br />
* Amphibians (number of individuals)<br />
* River morphology (soil depth and flow velocity)<br />
<br />
<br />
''Post-restoration monitoring''<br />
<br />
The same indicators used in the pre-restoration monitoring were monitored during the post-monitoring program in 2010 and 2011<br />
<br />
<br />
==Expectations and Response==<br />
<br />
It was expected that the new, large side channel would create a valuable sanctuary for many types of fish and amphibians. Two hectares of floodplain forest is expected to develop in the coming decades.<br />
<br />
''Ecology''<br />
The synopsis of the monitoring carried out in 2010 and 2011 do not show the monitoring results for the location Amlach/St. Peter for fish. The results of the monitoring for the combined projects of the LIFE project and the older GBK Obere Drau project show that the Grayling (Thymallus thymallus) has increased considerably with a doubling of the caught biomass, but it is still below the values measured in the end of the 1980s. Two species that show no improvement are the Danube salmon (Hucho hucho), which is close to complete extinction in the Upper Drava and self-sustaining reproduction could not be determined. The presence of common nase (Chondrostoma nasus) could only be determined by few individuals, but the population has not improved. <br />
<br />
Also for macro-invertebrates no results for the individual project Amlach/St. Peter were presented in the synopsis, but for all the projects 5 new species of spider and 8 species of carabid beetles were found of the total 130 species. Overall, the species richness of spiders and carabid beetles with specialized floodplain species returns.<br />
<br />
The number of amphibian species rapidly increased from 1 to 6 species.<br />
<br />
''Hydro-Morphology''<br />
<br />
A short period after the river widening in Amlach/St. Peter was completed, hydro-morphological processes affected the system strongly. The river bed responded to the discharge relief of the side channel with large sedimentation of 15 cm. The side channel was widened due to bank erosion to 7 meters and in the upstream part shows many sand and gravel banks. <br />
<br />
==Cooperation==<br />
<br />
The project was carried out by the Federal Ministry of Agriculture, Forestry, Environment and Water Management in cooperation with the Carinthian State Government and Torrent and avalanche control, section Carinthia. <br />
<br />
The main stakeholders were the land owners of the agricultural lands bordering the Drau river. <br />
<br />
==Communication==<br />
<br />
The communication with stakeholders and the general public was diverse. The project was opened with a large ceremony with a large attendance from the general public and politicians. A total of 70 project team meetings, 13 action days and 25 excursions were carried out.<br />

==General description==<br />
<br />
The Drau river is the fourth longest tributary of the Donau with a length of 707 km. The source of the river is in the Italian municipality Toblach where it continues its flow through Austria, Slovenia, Croatia and Hungary. The mouth of the river in the Donau is near the city of Osijek. <br />
<br />
The Upper Drau in Austria is an European protected area with the largest grey alder riparian forests of Austria and over 140 species of birds, including 51 red-listed species. The LIFE project ‘Life vein – Upper Drau River’ was carried out to counteract the trend of too narrow channels that are vulnerable for erosion and flooding by widening the river. Location Obergottesfeld is one of the project areas where the river was widened.<br />
<br />
<br />
==Pressures and Drivers==<br />
<br />
The Upper Drau is the last free-flowing, not dammed stretch of the river Drau. Nevertheless, human activity has changed the river and its floodplains. When a rail road line was build through the valley in 1870, regulatory procedures were carried out in order to reduce the flood danger and to expand intensive agricultural lands and settlements. The embankments created a narrow channel which suffered from bed erosion. The river bed deepened and wetlands and agricultural lands went dry with the sinking groundwater level. The stability of bank protection structures also suffered from the erosion.<br />
<br />
==Global objectives==<br />
<br />
The project has 4 global objectives<br />
<br />
* Further stabilization of the Drau river bed through widening and strengthening of bed load influx from tributary brooks.<br />
* More pristine, dynamic shaped river habitats<br />
* Improved information and visitor management on site<br />
* International cooperation with the respective authorities of the Drau neighboring states<br />
<br />

Obergottesfeld before and after the construction of the measures<br />
<br />
[[File:Obergottesfeld before after.JPG|500px|Image: 500 pixels]]<br />
<br />
==Measures selection==<br />
<br />
At Obergottesfeld, a part of the floodplain was given back to the river. The agricultural land made way for a side channels, oxbow lakes and standing bodies of water. A tributary was also widened to give it more space during a flood event. This improved the water retention in that area, as the river was free to flood the wider floodplain. Hidden built-in breakwaters were constructed to protect the banks during floods.<br />
<br />
==Monitoring==<br />
<br />
''Pre-restoration monitoring''<br />
<br />
A pre-restoration monitoring scheme was carried out to assess the current state of the location. The monitoring focuses on:<br />
<br />
* Habitats and animals on the Habitat and Birds Directive<br />
* Fish (presence of species and number of individuals)<br />
* Carabid beetles and other macro-invertebrates (number of species)<br />
* Amphibians (number of individuals)<br />
* River morphology (soil depth and flow velocity)<br />
<br />
''Post-restoration monitoring''<br />
<br />
The same indicators were monitored during the post-monitoring program. Since it was combined with an earlier LIFE project, the monitoring for fish, macro-invertebrates, most of the river morphology was not done in Obergottesfeld since it was not yet finished. Only amphibians and the flow velocity were measured. No further monitoring results could be found for Obergottesfeld.<br />
<br />
==Expectations and Response==<br />
<br />
The exact response of the measures on Obergottesfeld are not known because the latest found monitoring report was from 2011, the same year the Obergottesfeld project was finished. It is known that the flow velocity in the main channel decreased because of the side channel and there was a high number of individuals of amphibians.<br />
<br />
==Cooperation==<br />
<br />
The project was carried out by the Federal Ministry of Agriculture, Forestry, Environment and Water Management in cooperation with the Carinthian State Government and Torrent and avalanche control, section Carinthia. <br />
<br />
The main stakeholders were the land owners of the agricultural lands bordering the Drau river. <br />
<br />
==Communication==<br />
<br />
The communication with stakeholders and the general public was diverse. The project was opened with a large ceremony with a large attendance from the general public and politicians. A total of 70 project team meetings, 13 action days and 25 excursions were carried out.<br />

Rosenheim before and after the construction of the measures<br />
[[File:Rosenheim before after.JPG]]<br />
<br />
==Measures selection==<br />
<br />
At location Rosenheim (see figure above), a new side channel (1) and wetland ponds (5) were constructed. The side channel was fitted with steep banks on one side of the channel (3). An dead side channel was reconnected to the Drava (2) and a gravel bank was made (4).<br />
<br />
==Monitoring==<br />
<br />
''Pre-restoration monitoring''<br />
<br />
A pre-restoration monitoring scheme was carried out to assess the current state of the location. The monitoring focuses on:<br />
<br />
* Habitats and animals on the Habitat and Birds Directive<br />
* Fish (presence of species and number of individuals)<br />
* Carabid beetles and other macro-invertebrates (number of species)<br />
* Amphibians (number of individuals)<br />
* River morphology (soil depth and flow velocity)<br />
<br />
<br />
''Post-restoration monitoring''<br />
<br />
The same indicators used in the pre-restoration monitoring were monitored during the post-monitoring program in 2010 and 2011.<br />
<br />
==Expectations and Response==<br />
<br />
It was expected that new habitats would develop by the natural dynamics in the widened river section. The animal species would benefit from the new aquatic habitats. At the same time, the flood protection was improved by bank stabilization and a higher retention area. <br />
<br />
''Ecology''<br />
The synopsis of the monitoring carried out in 2010 and 2011 do not show the monitoring results for the location Rosenheim for fish. The results of the monitoring for the combined projects of the LIFE project and the older GBK Obere Drau project show that the Grayling (Thymallus thymallus) has increased considerably with a doubling of the caught biomass, but it is still below the values measured in the end of the 1980s. Two species that show no improvement are the Danube salmon (Hucho hucho), which is close to complete extinction in the Upper Drava and self-sustaining reproduction could not be determined. The presence of common nase (Chondrostoma nasus) could only be determined by few individuals, but the population has not improved. <br />
<br />
Also for macro-invertebrates no results for the individual project Rosenheim were presented in the synopsis, but for all the projects 5 new species of spider and 8 species of carabid beetles were found of the total 130 species. One of these species was the spider Arctosa cinerea, a species strictly related to gravelly-sandy river banks and nearly extinct in Austria. In Rosenheim, a new population of a few individuals was sighted. <br />
<br />
The number of amphibian species rapidly increased from 3 to 6 species with numerous sightings of adult Yellow-Bellied Toad (Bombina variegata). Close to location Rosenheim, slow worm (Anguis fragilis), grass snake (Natrix natrix) and Aesculapian Snake (Zamenis longissimus) were sighted. <br />
<br />
''Hydro-morphology''<br />
<br />
In Rosenheim, a sediment deficit is prevalent, causing deepening of the soil of 12 cm. This is less than when the old state of the river (29 to 23 cm). Only a small extent of the dynamic morphological processes took place at Rosenheim, due to the low sediment input into the widened section. This reduces the effectiveness of the measures. A reason for the high sediment deficit could be the tributary of the Möll river upstream. The tributary enlarges the discharge of the Drava, but does not transport the needed sediment.<br />
<br />
<br />
==Cooperation==<br />
<br />
The project was carried out by the Federal Ministry of Agriculture, Forestry, Environment and Water Management in cooperation with the Carinthian State Government and Torrent and avalanche control, section Carinthia. <br />
<br />
The main stakeholders were the land owners of the agricultural lands bordering the Drau river. <br />

==General description==<br />
<br />
The Drau river is the fourth longest tributary of the Donau with a length of 707 km. The source of the river is in the Italian municipality Toblach where it continues its flow through Austria, Slovenia, Croatia and Hungary. The mouth of the river in the Donau is near the city of Osijek. <br />
<br />
The Upper Drau in Austria is an European protected area with the largest grey alder riparian forests of Austria and over 140 species of birds, including 51 red-listed species. The LIFE project ‘Life vein – Upper Drau River’ was carried out to counteract the trend of too narrow channels that are vulnerable for erosion and flooding by widening the river. Location Rosenheim is close to a town of Drauhofen, St. Gertraud and Rosenheim. <br />
<br />
<br />
==Pressures and Drivers==<br />
<br />
The Upper Drau is the last free-flowing, not dammed stretch of the river Drau. Nevertheless, human activity has changed the river and its floodplains. When a rail road line was build through the valley in 1870, regulatory procedures were carried out in order to reduce the flood danger and to expand intensive agricultural lands and settlements. The embankments created a narrow channel which suffered from bed erosion. The river bed deepened and wetlands and agricultural lands went dry with the sinking groundwater level. The stability of bank protection structures also suffered from the erosion.<br />
<br />
==Global objectives==<br />
<br />
The project has 4 global objectives<br />
<br />
* Further stabilization of the Drau river bed through widening and strengthening of bed load influx from tributary brooks.<br />
* More pristine, dynamic shaped river habitats<br />
* Improved information and visitor management on site<br />
* International cooperation with the respective authorities of the Drau neighboring states<br />
<br />
==Specific objectives==<br />
<br />
No specific objectives could be found in the available project documents<br />
<br />
==Success Criteria==<br />
<br />
No success criteria could be found in the available project documents<br />
<br />
==Site description==<br />
<br />
==Measures selection==<br />
<br />
At location Rosenheim, a new side channel and wetland ponds were constructed. The side channel was fitted with steep banks on one side of the channel. An dead side channel was reconnected to the Drava and a gravel bank was made.<br />
<br />
==Monitoring==<br />
<br />
''Pre-restoration monitoring''<br />
<br />
A pre-restoration monitoring scheme was carried out to assess the current state of the location. The monitoring focuses on:<br />
<br />
* Habitats and animals on the Habitat and Birds Directive<br />
* Fish (presence of species and number of individuals)<br />
* Carabid beetles and other macro-invertebrates (number of species)<br />
* Amphibians (number of individuals)<br />
* River morphology (soil depth and flow velocity)<br />
<br />
<br />
''Post-restoration monitoring''<br />
<br />
The same indicators used in the pre-restoration monitoring were monitored during the post-monitoring program in 2010 and 2011.<br />
<br />
==Expectations and Response==<br />
<br />
It was expected that new habitats would develop by the natural dynamics in the widened river section. The animal species would benefit from the new aquatic habitats. At the same time, the flood protection was improved by bank stabilization and a higher retention area. <br />
<br />
''Ecology''<br />
The synopsis of the monitoring carried out in 2010 and 2011 do not show the monitoring results for the location Rosenheim for fish. The results of the monitoring for the combined projects of the LIFE project and the older GBK Obere Drau project show that the Grayling (Thymallus thymallus) has increased considerably with a doubling of the caught biomass, but it is still below the values measured in the end of the 1980s. Two species that show no improvement are the Danube salmon (Hucho hucho), which is close to complete extinction in the Upper Drava and self-sustaining reproduction could not be determined. The presence of common nase (Chondrostoma nasus) could only be determined by few individuals, but the population has not improved. <br />
<br />
Also for macro-invertebrates no results for the individual project Rosenheim were presented in the synopsis, but for all the projects 5 new species of spider and 8 species of carabid beetles were found of the total 130 species. One of these species was the spider Arctosa cinerea, a species strictly related to gravelly-sandy river banks and nearly extinct in Austria. In Rosenheim, a new population of a few individuals was sighted. <br />
<br />
The number of amphibian species rapidly increased from 3 to 6 species with numerous sightings of adult Yellow-Bellied Toad (Bombina variegata). Close to location Rosenheim, slow worm (Anguis fragilis), grass snake (Natrix natrix) and Aesculapian Snake (Zamenis longissimus) were sighted. <br />
<br />
''Hydro-morphology''<br />
<br />
In Rosenheim, a sediment deficit is prevalent, causing deepening of the soil of 12 cm. This is less than when the old state of the river (29 to 23 cm). Only a small extent of the dynamic morphological processes took place at Rosenheim, due to the low sediment input into the widened section. This reduces the effectiveness of the measures. A reason for the high sediment deficit could be the tributary of the Möll river upstream. The tributary enlarges the discharge of the Drava, but does not transport the needed sediment.<br />
<br />
<br />
==Cooperation==<br />
<br />
The project was carried out by the Federal Ministry of Agriculture, Forestry, Environment and Water Management in cooperation with the Carinthian State Government and Torrent and avalanche control, section Carinthia. <br />
<br />
The main stakeholders were the land owners of the agricultural lands bordering the Drau river. <br />
<br />
==Communication==<br />
<br />
The communication with stakeholders and the general public was diverse. The project was opened with a large ceremony with a large attendance from the general public and politicians. A total of 70 project team meetings, 13 action days and 25 excursions were carried out.<br />
<br />

==General description==<br />
<br />
The Drau river is the fourth longest tributary of the Donau with a length of 707 km. The source of the river is in the Italian municipality Toblach where it continues its flow through Austria, Slovenia, Croatia and Hungary. The mouth of the river in the Donau is near the city of Osijek. <br />
<br />
The Upper Drau in Austria is an European protected area with the largest grey alder riparian forests of Austria and over 140 species of birds, including 51 red-listed species. The LIFE project ‘Life vein – Upper Drau River’ was carried out to counteract the trend of too narrow channels that are vulnerable for erosion and flooding by widening the river. Location Obergottesfeld is one of the project areas where the river was widened.<br />
<br />
<br />

<br />
==Site description==<br />
<br />
==Measures selection==<br />
<br />
At Obergottesfeld, a part of the floodplain was given back to the river. The agricultural land made way for a side channels, oxbow lakes and standing bodies of water. A tributary was also widened to give it more space during a flood event. This improved the water retention in that area, as the river was free to flood the wider floodplain. Hidden built-in breakwaters were constructed to protect the banks during floods.<br />
<br />
==Monitoring==<br />
<br />
''Pre-restoration monitoring''<br />
<br />
A pre-restoration monitoring scheme was carried out to assess the current state of the location. The monitoring focuses on:<br />
<br />
* Habitats and animals on the Habitat and Birds Directive<br />
* Fish (presence of species and number of individuals)<br />
* Carabid beetles and other macro-invertebrates (number of species)<br />
* Amphibians (number of individuals)<br />
* River morphology (soil depth and flow velocity)<br />
<br />
''Post-restoration monitoring''<br />
<br />
The same indicators were monitored during the post-monitoring program. Since it was combined with an earlier LIFE project, the monitoring for fish, macro-invertebrates, most of the river morphology was not done in Obergottesfeld since it was not yet finished. Only amphibians and the flow velocity were measured. No further monitoring results could be found for Obergottesfeld.<br />
<br />
==Expectations and Response==<br />
<br />
The exact response of the measures on Obergottesfeld are not known because the latest found monitoring report was from 2011, the same year the Obergottesfeld project was finished. It is known that the flow velocity in the main channel decreased because of the side channel and there was a high number of individuals of amphibians.<br />
<br />
==Cooperation==<br />
<br />
The project was carried out by the Federal Ministry of Agriculture, Forestry, Environment and Water Management in cooperation with the Carinthian State Government and Torrent and avalanche control, section Carinthia. <br />
<br />

==General description==<br />
<br />
The Drau river is the fourth longest tributary of the Donau with a length of 707 km. The source of the river is in the Italian municipality Toblach where it continues its flow through Austria, Slovenia, Croatia and Hungary. The mouth of the river in the Donau is near the city of Osijek. <br />
<br />
The Upper Drau in Austria is an European protected area with the largest grey alder riparian forests of Austria and over 140 species of birds, including 51 red-listed species. The LIFE project ‘Life vein – Upper Drau River’ was carried out to counteract the trend of too narrow channels that are vulnerable for erosion and flooding by widening the river. Location Obergottesfeld is one of the project areas where the river was widened.<br />
<br />
<br />
==Pressures and Drivers==<br />
<br />
The Upper Drau is the last free-flowing, not dammed stretch of the river Drau. Nevertheless, human activity has changed the river and its floodplains. When a rail road line was build through the valley in 1870, regulatory procedures were carried out in order to reduce the flood danger and to expand intensive agricultural lands and settlements. The embankments created a narrow channel which suffered from bed erosion. The river bed deepened and wetlands and agricultural lands went dry with the sinking groundwater level. The stability of bank protection structures also suffered from the erosion.<br />
<br />
==Global objectives==<br />
<br />
The project has 4 global objectives<br />
<br />
* Further stabilization of the Drau river bed through widening and strengthening of bed load influx from tributary brooks.<br />
* More pristine, dynamic shaped river habitats<br />
* Improved information and visitor management on site<br />
* International cooperation with the respective authorities of the Drau neighboring states<br />
<br />
==Specific objectives==<br />
<br />
No specific objectives could be found in the available project documents<br />
<br />
==Success Criteria==<br />
<br />
No success criteria could be found in the available project documents<br />
<br />
==Site description==<br />
<br />
==Measures selection==<br />
<br />
At Obergottesfeld, a part of the floodplain was given back to the river. The agricultural land made way for a side channels, oxbow lakes and standing bodies of water. A tributary was also widened to give it more space during a flood event. This improved the water retention in that area, as the river was free to flood the wider floodplain. Hidden built-in breakwaters were constructed to protect the banks during floods.<br />
<br />
==Monitoring==<br />
<br />
''Pre-restoration monitoring''<br />
<br />
A pre-restoration monitoring scheme was carried out to assess the current state of the location. The monitoring focuses on:<br />
<br />
* Habitats and animals on the Habitat and Birds Directive<br />
* Fish<br />
* Carabid beetles and other macro-invertebrates<br />
* Amphibians<br />
* River morphology<br />
<br />
The exact methods of monitoring could not be found in the available documents<br />
<br />
''Post-restoration monitoring''<br />
<br />
The same indicators were monitored during the post-monitoring program. Since it was combined with an earlier LIFE project, the monitoring for fish, macro-invertebrates, most of the river morphology was not done in Obergottesfeld since it was not yet finished. Only amphibians and the flow velocity were measured. No further monitoring results could be found for Obergottesfeld.<br />
<br />
<br />
==Expectations and Response==<br />
<br />
The exact response of the measures on Obergottesfeld are not known because the latest found monitoring report was from 2011, the same year the Obergottesfeld project was finished. It is known that the flow velocity in the main channel decreased because of the side channel and there was a high number of individuals of amphibians.<br />
<br />
==Cooperation==<br />
<br />
The project was carried out by the Federal Ministry of Agriculture, Forestry, Environment and Water Management in cooperation with the Carinthian State Government and Torrent and avalanche control, section Carinthia. <br />
<br />
The main stakeholders were the land owners of the agricultural lands bordering the Drau river. <br />
<br />
==Communication==<br />
<br />
The communication with stakeholders and the general public was diverse. The project was opened with a large ceremony with a large attendance from the general public and politicians. A total of 70 project team meetings, 13 action days and 25 excursions were carried out.<br />
<br />

==General description==<br />
<br />
Polder Altenheim is a 520 ha floodplain in the Upper Rhine (Rhine km 278 till 284) near the village of Altenheim. The floodplain has functioned as a controlled water retention area since 1987. Later, ecological flooding was introduced to restore the flood plain nature. 65 days per year river water is allowed to enter Polder Altenheim. It is now one of the oldest natural flood protection projects in Europe<br />
<br />
<br />
==Pressures and Drivers==<br />
<br />
The Upper Rhine suffers from hydrological regime modifications by artificial barriers upstream and downstream of Polder Altenheim. These barriers, along with channelization and embankments were built in order to control flooding of settlements in the floodplains of the Upper Rhine and for generating hydropower. The weirs now have a negative effect on the flood protection, since they impound the river blocking the discharge during high water events. <br />
<br />
<br />
==Global objectives==<br />
<br />
The global objectives were two sided. First, the projects initial goal was to restore the flood water retention capacity of the Upper Rhine to pre-weir conditions. Later, the restoration of typical Rhine floodplain nature in Polder Altenheim was added as global objective.<br />
<br />
<br />
==Specific objectives==<br />
<br />
The specific objectives for Polder Altenheim could not be found in the project documents and the question was not answered by the project manager in time. There are possible objectives for flood protection as well as some ecological targets concerning habitats, but this remains uncertain.<br />
<br />
<br />
==Success Criteria==<br />
<br />
No success criteria were mentioned in the project documents.<br />
<br />
<br />
==Site description==<br />
<br />
[[File:Map polder altenheim.JPG ]]<br />
<br />
==Measures selection==<br />
<br />
To improve the water retention capacity while retaining a natural flooding frequency, two polders (Altenheim II and Altenheim I) are connected to the main river by a controlled inlet. These inlets are designed to flood parts of the polders 65 days per year. When there is a higher discharge of once per 10 years, the polders will automatically flood to increase the retention capacity of the river. The outlet of Polder Altenheim I is connected to the retention area, Kulturwehr Kehl/Straßburg. In the polder, the dynamics caused by the ecological flooding are allowed to shape the habitats.<br />
<br />
<br />
==Monitoring==<br />
<br />
''Pre-restoration monitoring''<br />
<br />
No evidence for pre-restoration monitoring could be found in the project documents<br />
<br />
''Post-restoration monitoring''<br />
<br />
In 1993 till 1996, a large monitoring program was carried out in Polder Altenheim. In this program, the quantitative changes of reeds and forests, the number of species and presence of species of macro-invertebrates (Carabidae, land snails, spiders, grasshoppers, bees, female mosquitos), the number of caught fish, the number of caught individuals of birds, small mammals and amphibians and number of breeding pairs of birds, the total flooded area in different discharge scenarios and changes in characteristics of the soil and groundwater were measured from 1993 till 1996.<br />
<br />
<br />
==Expectations and Response==<br />
<br />
It was expected that the ecological flooding regime has a positive effect on the floodplain habitats. The flood retention capacity of the Upper Rhine is enlarged and at the same time a recreation area for the local residents is created.<br />
<br />
''Ecology''<br />
<br />
The response of the ecology was positive. The ecological flooding saw an increase in reeds, floodplain forest and other characteristic species of the floodplain. Typical mammal species of the floodplain also increased in the zones which were affected by ecological flooding, like the harvest mouse (Micromys minutus) which inhabits reed marches and the common shrew (Sorex araneus) and the wood mouse (Apodemus sylvat) that live in the Alder forests. The number of typical flood plain bird species also benefited from the ecological flooding. For example, the number of breeding pairs of Common Kingfisher (Alcedo atthis) increased from 4 breeding pairs in 1988 to 9 breeding pairs in 1996. Amphibians also increased in numbers between the start of Polder Altenheim as retention area in 1988 and the last monitoring event in 1996. The European tree frog (Hyla arborea), an species on the red list in Germany and a characteristic floodplain species, increased rapidly in numbers from a few individuals to 28 calling males in 1996. In 1998, the numbers increased to 100 calling males. The percentage of rheophilic fish species, Dace (Leuciscus leuciscus), Stone loach (Barbatula barbatula) and chub (Leuciscus cephalus) increased from a maximum of 5% in 1993 to 10 to 15% in 1996. The macro-invertebrates showed a positive response to the measures. The population size increased and habitats were recolonized. <br />
<br />
''Social-economic factors''<br />
<br />
The ecological flooding had no negative effect on the areas outside of the floodplain and the water retention during high discharges function well. The effects on other land uses were not described in the monitoring report.<br />
<br />
<br />
==Cooperation==<br />
<br />
The project was part of the Integriertes Rheinprogramm and was constructed by Wasser-und Schifffahrtsamt Freiburg in cooperation with Landes Baden-Württemberg<br />
<br />
==Communication==<br />
<br />
The communication strategy of Polder Altenheim could not be found in the available documents<br />
<br />
<br />
==Funding==<br />
<br />
The total costs of building the controlled inlets and the ecological monitoring were 28 million Euro which was financed by the Federal State and the National government.<br />

In this program, the quantitative changes of reeds and forests, the number of species and presence of species of macro-invertebrates (Carabidae, land snails, spiders, grasshoppers, bees, female mosquitos), the number of caught fish, the number of caught individuals of birds, small mammals and amphibians and number of breeding pairs of birds, the total flooded area in different discharge scenarios and changes in characteristics of the soil and groundwater were measured from 1993 till 1996.<br />
<br />
<br />
==Expectations and Response==<br />
<br />
It was expected that the ecological flooding regime has a positive effect on the floodplain habitats. The flood retention capacity of the Upper Rhine is enlarged and at the same time a recreation area for the local residents is created.<br />
<br />
''Ecology''<br />
<br />
The response of the ecology was positive. The ecological flooding saw an increase in reeds, floodplain forest and other characteristic species of the floodplain. Typical mammal species of the floodplain also increased in the zones which were affected by ecological flooding, like the harvest mouse (Micromys minutus) which inhabits reed marches and the common shrew (Sorex araneus) and the wood mouse (Apodemus sylvat) that live in the Alder forests. The number of typical flood plain bird species also benefited from the ecological flooding. For example, the number of breeding pairs of Common Kingfisher (Alcedo atthis) increased from 4 breeding pairs in 1988 to 9 breeding pairs in 1996. Amphibians also increased in numbers between the start of Polder Altenheim as retention area in 1988 and the last monitoring event in 1996. The European tree frog (Hyla arborea), an species on the red list in Germany and a characteristic floodplain species, increased rapidly in numbers from a few individuals to 28 calling males in 1996. In 1998, the numbers increased to 100 calling males. The percentage of rheophilic fish species, Dace (Leuciscus leuciscus), Stone loach (Barbatula barbatula) and chub (Leuciscus cephalus) increased from a maximum of 5% in 1993 to 10 to 15% in 1996. The macro-invertebrates showed a positive response to the measures. The population size increased and habitats were recolonized. <br />
<br />
''Social-economic factors''<br />
<br />
The ecological flooding had no negative effect on the areas outside of the floodplain and the water retention during high discharges function well. The effects on other land uses were not described in the monitoring report.<br />
<br />

==Cooperation==<br />
<br />
The project was part of the Integriertes Rheinprogramm and was constructed by Landes Baden-Württemberg<br />

==General description==<br />
<br />
The Hampshire Avon catchment is on of the most bio diverse catchments in the UK, with over 180 species of aquatic plants, 37 species of fish and a wide range of aquatic invertebrates. The river has a high input from chalk-rich water from springs in the headwaters. Therefore the catchment is a Special Area of Conservation (SAC), which is part of the Natura 2000 network. As a calcareous river, it is an important habitat for several endangered species like Atlantic salmon (Salmo salar), bullhead (Cottus gobio), brook lamprey (Lampetra planeri), sea lamprey (Petromyzon marinus) and Desmoulin’s whorl snail (Vertigo moulinsiana). The vegetation community consists of a Ranunculion fluitantis /Callitricho-Batrachion community.<br />
<br />
Location Seven Hatches is located close to the confluence of the river Wylye and the Nadder. Several impoundments are present on the site. First it is characterized by the presence of a large radial sluices replacing the original hatches that gave this location its name. Just above the sluices, the river splits into two channels, the main Wylye also known as the ‘Union’ and the ‘Butcher Stream’. Next to the sluices, the footings of a railway bridge upstream and a tractor bridge downstream are present. A small chalk stream called Law’s Ditch flows into the Wylye below the railway crossing, but it is culverted underneath the Butcher Stream for 600 meters.<br />
<br />
==Pressures and Drivers==<br />
<br />
A conservation strategy has been written for the Avon River and its tributaries in 2003. In this document, the main pressures on the ecosystem of the Avon are pollution, fisheries (both commercial and recreational) and flood defence. These pressures come from a variety of drivers, namely agriculture, industry, fisheries, recreation and flood protection. Historical dredging has damaged the river ecosystem by destruction of habitats, loss of lateral connectivity, silting up of clean gravel habitats and unnatural river flows. At location Seven Hatches, the impoundments caused by the sluices, the footing of the railway bridge and the footing of the tractor bridge have resulted in siltation due to slower flows. In combination with the historical dredging, this has lead to a loss of hard bed structures, over widening of the channel and the creation of raised floodplains. The hydrological connectivity with the floodplain has been lost and the grazing pressure of livestock has damaged riparian vegetation structures and caused erosion at some sites.<br />
<br />
<br />
==Global objectives==<br />
<br />
The global objective of the STREAM demonstration project is to restore the River Avon Special Area of Conservation (SAC) and Special Site of Scientific Interest (SSSI) to favourable conditions while addressing wider biodiversity issues outside the protected areas. Another important objective is increasing public awareness for the importance of the river and valley as natural heritage by improving public access.<br />
<br />
==Specific objectives==<br />
<br />
The location of Seven Hatches had several specific objectives:<br />
<br />
* Modify the operation of the Seven Hatches sluices, reducing height by an average of 0.15 metres, thus increasing ecological connectivity between reaches and improving upstream habitat quality.<br />
<br />
* Restore the historic bed level and increase the heterogeneity of bed morphology in previously dredged reaches by the reclamation and re-introduction of excavated gravel/stone bed material<br />
<br />
* Narrow overwide channels where necessary, in order to re-establish a sinuous channel of appropriate cross-sectional area with respect to present day hydrographs<br />
<br />
* Increase the amount of large woody debris in the channel in order to increase both the availability of this habitat type and morphological diversity of the channel<br />
<br />
* Break out and remove the tractor bridge footings and replace with a single span bridge. To remove the impounding effect of the structure<br />
<br />
* Enhance the availability and quality of habitat for SAC species and habitats, in particular:<br />
** Bullhead (Cottus gobio) (increased diversity of hard bed, particularly pools during winter and riffle/fast glides during summer and increased large woody debris for, particularly, juveniles)<br />
** Brook lamprey (Lampetra planeri) (increased availability of well sorted, fine sediment in shaded, marginal areas with large woody debris for ammocoetes and gravel/sand dominated shallows <40 cm deep for spawning adults)<br />
** Salmon parr (Salmo salar) (increased availability of coarse substrate, with overhead cover and woody debris lodged in the channel)<br />
** Desmoulin’s whorl snail (Vertigo moulinsiana) in the marginal zone of the channel<br />
** The Ranunculus community as a result of increased heterogeneity in velocity and bed morphology<br />
<br />
==Success Criteria==<br />
<br />
In the original bidding document a value for the minimal increase in spawning habitat was given, but the exact value is not known. There was also a target for increasing hydro-morphological diversity, but no exact value was given. No other clear qualitative or quantitative success criteria for other hydro-morphological, biological or flood protection targets were defined for the project.<br />
<br />
==Site description==<br />
<br />
==Measures selection==<br />
<br />
The Seven Hatches restoration site was divided in 7 reaches. No measures were planned for reach 1 and 7. In reach 2, 4 and 6, deflectors are installed to narrow the channel. The deflector in reach 2 will be based on a D-shaped outlined with wooden stakes and then filled with brushwood. In reach 4, the deflector is made with large woody debris and in reach 6, tree deflectors are constructed. Next to the deflectors, gravels are also imported in reach 4 and trees are removed. It was planned to re-grade existing banks, but this was later cancelled due to the limited machine access and minimal effect on the hydrology. Fences are used to prevent grazing of the banks by livestock. Native trees are planted to compensate for the removal of unsuitable tree species. It was planned to replace the tractor bridge, but this was later cancelled due to limited effect on the hydrology. It was planned to lower the sluices at Seven Hatches (reach 3) with an average of 0.15 meters, but this was later cancelled to protect salmon habitat upstream and fear for flooding problems in the Witton area. <br />
<br />
<br />
==Monitoring==<br />
<br />
''Pre-restoration monitoring''<br />
<br />
In Seven Hatches, a detailed pre-restoration monitoring scheme was implemented. The detailed assessment method consists, namely physical biotope mapping, river corridor survey, macrophyte survey, cross-sectional mapping, depth/velocity/substrate survey, fisheries survey and repeat fixed point photography. The exact methods are described in the Monitoring Protocol.<br />
<br />
''Post-restoration monitoring''<br />
<br />
The post-restoration monitoring occurred 18 months after the project was finished. The monitoring methods were the same as the pre-restoration assessment. <br />
<br />
Separate from the LIFE project in Seven Hatches some invertebrate monitoring was conducted before and after the measures, but the results of this survey was not reported in the project reports.<br />
<br />
==Expectations and Response==<br />
<br />
It was expected that the measures would have a positive effect on the river ecology, especially on bullhead, brook lamprey and salmonids due to the introduced hard bed substrates. A greater heterogeneity in substrates was expected which would result in re-establishment of Ranunculus and other macrophyte species. The increased hydrological continuity with the floodplain and exclusion of cattle benefits the riparian zone and typical riparian species. <br />
<br />
<br />
''Ecological Response''<br />
<br />
A total of 58 macrophyte taxa were recorded during the assessment of 5 transects. No invasive species were found and only one negative indicator Fennel pondweed was found. The key species brook water-crowfoot and hemlock water dropwort were only minimally present with less than 5% coverage. The most dominant species were Reed sweet grass and branched bur-reed with both species taking 10% of the coverage. <br />
<br />
Compared to the pre-restoration state, the reach has less brook water-crowfoot and a strong increase in the negative indicator Fennel pondweed. A fewer number of taxa were observed and a reduced number of species were recorded as covering more than 5% of the channel. It was concluded that temporary disturbance caused by the construction of the measures could be the cause of this decrease. The installation of fences did increase marginal vegetation growth at some cross sections. <br />
<br />
The fish survey 11 species of fish were caught in 2008 compared to 10 in 2006. There was an large increase in salmon, trout and bullhead, but a decrease in lamprey and minnow. The higher flow conditions in 2008 could be the reason why there was more bullhead and salmon, who prefer swift flowing water, and lamprey and minnow, who prefer more shallow water.<br />
<br />
<br />
''Hydro-morphological Response''<br />
<br />
The physical biotopes mostly glide and a few pools, observed in 2008 were the same as in 2006, with the exception of the created riffles. The riffles had an impact on the sediment regime, with more localized areas of sediment deposition and transport. The exclusion of livestock also decreased the input of fine sediment and an increase in sediment trapping margin vegetation. <br />
<br />
The physical channel form was significantly changed by the measures. The depth decreased where the bed of the channel had been raised. However, the higher water level in 2008 minimized the decrease in water depth even at the riffles. Also the change in velocity was minimal due to the higher discharge in 2008 compared to 2006. There was however more coarse material and less coverage of silt. <br />
<br />
The complete dataset and more detailed information can be found in the report ‘Physical and biological monitoring of STREAM restoration projects: Year three report’<br />
<br />
<br />
''Social-economic Response''<br />
<br />
The impact of the measures on socio-economic aspects like flood protection are not monitored and therefore unknown. The Hampshire Avon Catchment Flood Management Plan published in 2009 indicates that the area of Seven Hatches is on the border between the Salisbury area with policy 5, Areas of moderate to high flood risk where we can generally take further action to reduce flood risk, and the Upper Avon, Wylye sub area with policy 6, Areas of low to moderate flood risk where we will take action with others to store water or manage run-off in locations that provide overall flood risk reduction or environmental benefits. There are therefore still problems with flood protection that have to be addressed.<br />
<br />
==Cooperation==<br />
<br />
The project was carried out by Natural England in cooperation with the Environment agency, Wiltshire Wildlife Trust, Hampshire & Isle of Wight Wildlife Trust, Wessex Water and the River Restoration Centre (Advisory role).<br />
<br />
The local stakeholders where the local landowners, tenant farmers and the fishing clubs that owned the fishing rights<br />
<br />
<br />
==Communication==<br />
<br />
During the planning phase, the public was informed via public meetings and press releases in the newspapers and magazines. The stakeholders had to accept the concept design in the project bid and during the project there was constant contact with the stakeholders. Concerns or criticisms were investigated and the project changed when the criticisms were verified. At the end of the project a conference was held for all stakeholders and general public to show them the end results of the project in their area.<br />
<br />
==Funding==<br />
<br />
The total costs of the project were £1 million pounds. 40% of this total costs was paid for by the European Union via LIFE subsidies. The rest of the costs were paid for by the state, a water company and 2 wild life trusts.<br />

==General description==<br />
<br />
The Hampshire Avon catchment is on of the most bio diverse catchments in the UK, with over 180 species of aquatic plants, 37 species of fish and a wide range of aquatic invertebrates. The river has a high input from chalk-rich water from springs in the headwaters. Therefore the catchment is a Special Area of Conservation (SAC), which is part of the Natura 2000 network. As a calcareous river, it is an important habitat for several endangered species like Atlantic salmon (Salmo salar), bullhead (Cottus gobio), brook lamprey (Lampetra planeri), sea lamprey (Petromyzon marinus) and Desmoulin’s whorl snail (Vertigo moulinsiana). The vegetation community consists of a Ranunculion fluitantis /Callitricho-Batrachion community.<br />
<br />
<br />
Location Hale is located in the Lower Avon area, just upstream of the town of Fordingbridge.<br />
<br />
==Pressures and Drivers==<br />
<br />
A conservation strategy has been written for the Avon River and its tributaries in 2003. In this document, the main pressures on the ecosystem of the Avon are pollution, fisheries (both commercial and recreational) and flood defence. These pressures come from a variety of drivers, namely agriculture, industry, fisheries, recreation and flood protection. Historical dredging has damaged the river ecosystem by destruction of habitats, loss of lateral connectivity, silting up of clean gravel habitats and unnatural river flows. At the location of Hale, the river is fast flowing with little flow variability within the channel. Historical land drainage works by dredging has made the channel too wide and deep with deposited spoil on the right and left banks. The hydrological connection with the floodplain was lost. The floodplains were used as grazing areas for cattle and sheep, slowing the development of a vegetation community which could facilitate a stable narrowing of the channel. In addition, the submerged macrophyte diversity is poor with a few dominating species. <br />
<br />
Due to the dredging, the river bed is dominated by poorly sorted fine gravel and sand, a substrate with very limited spawning opportunities and fry habitat for salmonid species. Since there was a lack of riparian shrubs and trees, there was very little large woody debris present in the stream and little shading.<br />
<br />
==Global objectives==<br />
<br />
The global objective of the STREAM demonstration project is to restore the River Avon Special Area of Conservation (SAC) and Special Site of Scientific Interest (SSSI) to favourable conditions while addressing wider biodiversity issues outside the protected areas. Another important objective is increasing public awareness for the importance of the river and valley as natural heritage by improving public access.<br />
<br />
==Specific objectives==<br />
<br />
The restoration works at location Hale had several specific objectives:<br />
<br />
* Re-energise the reach by providing variations in flow characteristics and channel dimensions (improve channel structure)<br />
<br />
* Increase both the heterogeneity of bed morphology and margins in previously dredged reaches (improve substrate structure)<br />
<br />
* Increase the availability of suitable spawning habitat for salmon, bullhead and brook lamprey<br />
<br />
* Increase the amount of woody debris in the channel in order to increase both the availability of this habitat type and morphological diversity of the channel<br />
<br />
* Enhance the availability and quality of habitat for, in particular<br />
** Bullhead (Cottus gobio) (increased diversity of hard bed, particularly pools during winter and riffle/fast glides during summer and increased large woody debris for, particularly, juveniles)<br />
** Brook lamprey (Lampetra planeri) (increased availability of well sorted, fine sediment in shaded, marginal areas with large woody debris for ammocoetes and gravel/sand dominated shallows <40 cm deep for spawning adults)<br />
** Salmon parr (Salmo salar) (increased availability of coarse substrate, with overhead cover and woody debris lodged in the channel)<br />
** Desmoulin’s whorl snail (Vertigo moulinsiana) in the marginal zone of the channel<br />
** The Ranunculus community as a result of increased heterogeneity in velocity and bed morphology<br />
<br />
==Success Criteria==<br />
<br />
In the bidding documents for the permits, there was a criteria value of spawning habitats. There was also the criterion to increase morphological diversity, but this was not quantified by a value<br />
<br />
==Site description==<br />
<br />
==Measures selection==<br />
<br />
Location Hale was divided in 7 reaches. No measures were planned for reach 1 and reach 7. At two locations (Reach 2 and 4) 30-40 meter spawning riffles were created using existing and imported gravels. The existing gravels are used to create a stable crest. Gravels are placed on top and below the crest of the riffle to provide a suitable depth for spawning. <br />
<br />
<br />
In two reaches (Reach 4 and 6) upstream current deflectors were constructed to create a varying flow and to narrow the channel. These deflectors are made of large tree limbs set at angles between 30° and 60° and are 12-15 meters in length. The tree limbs are secured to prevent washing away.<br />
<br />
<br />
Woody debris is added at all reaches (except reach 1 and 7). In reach 2, native trees were planted to serve as future source of woody debris. Temporary fencing is placed to protect the trees from graving by livestock. In the other reaches, trees were coppiced or pollarded to get woody debris in the stream. In reach 5, the woody debris was used to install a tree kicker.<br />
<br />
==Monitoring==<br />
<br />
''Pre-restoration monitoring''<br />
<br />
At location Hale, a rapid assessment survey was done during pre- and post-monitoring. The rapid assessment survey consists of a physical biotope survey where biotopes were mapped and a river corridor survey to assess vegetation. The assessment is based on expert judgment, although the method has possibilities to add qualitative and quantitative results of analysis undertaken for particular elements. The pre-monitoring effort was to record the hydro-morphological and biological conditions of the site before any measures where taken.<br />
<br />
''Post-restoration monitoring''<br />
<br />
The post-monitoring occurred two years later using the same monitoring techniques. The results are compared to see if the restoration measures had any effect on the site.<br />
<br />
==Expectations and Response==<br />
<br />
The positive results of the restoration measures mostly involve the expected increase of flow variability by the reshaping of the channel. The created riffles were expected to promote local sediment transport and flow variability which results in a change of substrate composition of the river bed from sand/silt dominated to gravel/pebbles dominated. Growth of Ranunculus and other aquatic plants should be increased on the riffles. The riffles also provide a suitable spawning habitat for salmon (S. salar) which would have positive results on the population size of this species. <br />
<br />
<br />
The planted trees would increase habitat for terrestrial invertebrates and nesting birds. Large woody debris deflectors at reach 6 would promote geomorphological processes like sedimentation of silt. Brook lamprey (L. planeri) should benefit from the increased habitat opportunities created by the woody debris. The improvement of the vegetation should develop habitat suitable for Desmoulin’s whorl snail (V. moulinsiana).<br />
<br />
<br />
''Ecological response''<br />
<br />
Fish, macro-invertebrates and phytoplankton were not surveyed, so the effect of the restoration measures on these biological quality indicators is not known. Barble has been seen to be spawning on the riffles, but this was not an official part of the monitoring process.<br />
<br />
<br />
The vegetation structure and species diversity appears to be similar to the pre-monitoring. Water crowfoot (Ranunculus penicillatus) occurs intermittently along the channel. No other macrophytes are found in the post-monitoring. In the pre-montoring, horned pondweed (Zannichellia palustris) was present in the river. <br />
<br />
<br />
The riparian buffer zone varies from narrow to non-existent in case of grasslands which support sheep and cattle grazing. Upstream broadleaved woodland is present on the left bank with sycamore (Acer pseudoplatanus) and ash (Fraxinus excelsior) with occasional willow (Salix sp.) and English oak (Quercus robur). On the left bank, reeds like reed sweet grass (Glyceria maxima), common reed (Phragmites australis) and reed canary grass (Phalaris arundinacea) are present with occasional hawthorn (Crataegus monogyna) and bramble (Rubus fruticosus agg.). Downstream, both banks have similar vegetation. Dominant species are reed sweet grass (G. maxima) and common nettle (Urtica dioica) with other species like yellow flag iris (Iris pseudacorus), reed canary grass (P. arundinacea), bramble (R. fruticosa), water mint (Mentha aquatic), great willow herb (Epilobium hirsutum), branched bur-reed (Sparganium erectum) and occasional alders (Alnus glutinosa).<br />
<br />
<br />
''Hydro-morphological response''<br />
<br />
The dominant physical biotope at the Hale site was glide. At the start of the last meander bend, a deep pool was observed. Upwelling was observed at two locations. It should be noted that the discharge and water levels were high and this could have obscured localised diversity created by the restoration measures. The two areas of upwelling can be related to the large riffle upstream of the first upwelling area and the woody debris deflectors within the second upwelling area. <br />
<br />
Due to the high water level during the post-monitoring, the influence of the restoration measures on the patterns of sediment deposition in the channel bed could not be assessed. Bank erosion at meander bends is reduced due to increased marginal vegetation and local exclusion of livestock by through fencing. <br />
<br />
<br />
''Socio-economic response''<br />
<br />
The impact of the measures on socio-economic aspects like flood protection are not monitored and therefore unknown. There was speculation that the increase in marginal vegetation cover is related to the sustained higher water levels in 2007 and 2008 at the time of the survey. The Hampshire Avon Catchment Flood Management Plan published in 2009 indicates that the area of Hale has sufficient flood risk management, but could be improved to cope with future climate change.<br />
<br />
==Cooperation==<br />
<br />
During the planning phase, the public was informed via public meetings and press releases in the newspapers and magazines. The stakeholders had to accept the concept design in the project bid and during the project there was constant contact with the stakeholders. Concerns or criticisms were investigated and the project changed when the criticisms were verified. At the end of the project a conference was held for all stakeholders and general public to show them the end results of the project in their area.<br />
<br />
==Funding==<br />
<br />
The total costs of the project were £1 million pounds. 40% of this total costs was paid for by the European Union via LIFE subsidies. The rest of the costs were paid for by the state, a water company and 2 wild life trusts.<br />

==General description==<br />
<br />
The Hampshire Avon catchment is on of the most bio diverse catchments in the UK, with over 180 species of aquatic plants, 37 species of fish and a wide range of aquatic invertebrates. The river has a high input from chalk-rich water from springs in the headwaters. Therefore the catchment is a Special Area of Conservation (SAC), which is part of the Natura 2000 network. As a calcareous river, it is an important habitat for several endangered species like Atlantic salmon (Salmo salar), bullhead (Cottus gobio), brook lamprey (Lampetra planeri), sea lamprey (Petromyzon marinus) and Desmoulin’s whorl snail (Vertigo moulinsiana). The vegetation community consists of a Ranunculion fluitantis /Callitricho-Batrachion community.<br />
<br />
<br />
Location Hale is located in the Lower Avon area, just upstream of the town of Fordingbridge.<br />
<br />
==Pressures and Drivers==<br />
<br />
A conservation strategy has been written for the Avon River and its tributaries in 2003. In this document, the main pressures on the ecosystem of the Avon are pollution, fisheries (both commercial and recreational) and flood defence. These pressures come from a variety of drivers, namely agriculture, industry, fisheries, recreation and flood protection. Historical dredging has damaged the river ecosystem by destruction of habitats, loss of lateral connectivity, silting up of clean gravel habitats and unnatural river flows. At the location of Hale, the river is fast flowing with little flow variability within the channel. Historical land drainage works by dredging has made the channel too wide and deep with deposited spoil on the right and left banks. The hydrological connection with the floodplain was lost. The floodplains were used as grazing areas for cattle and sheep, slowing the development of a vegetation community which could facilitate a stable narrowing of the channel. In addition, the submerged macrophyte diversity is poor with a few dominating species. <br />
<br />
Due to the dredging, the river bed is dominated by poorly sorted fine gravel and sand, a substrate with very limited spawning opportunities and fry habitat for salmonid species. Since there was a lack of riparian shrubs and trees, there was very little large woody debris present in the stream and little shading.<br />
<br />
==Global objectives==<br />
<br />
The global objective of the STREAM demonstration project is to restore the River Avon Special Area of Conservation (SAC) and Special Site of Scientific Interest (SSSI) to favourable conditions while addressing wider biodiversity issues outside the protected areas. Another important objective is increasing public awareness for the importance of the river and valley as natural heritage by improving public access.<br />
<br />
==Specific objectives==<br />
<br />
The restoration works at location Hale had several specific objectives:<br />
<br />
* Re-energise the reach by providing variations in flow characteristics and channel dimensions (improve channel structure)<br />
<br />
* Increase both the heterogeneity of bed morphology and margins in previously dredged reaches (improve substrate structure)<br />
<br />
* Increase the availability of suitable spawning habitat for salmon, bullhead and brook lamprey<br />
<br />
* Increase the amount of woody debris in the channel in order to increase both the availability of this habitat type and morphological diversity of the channel<br />
<br />
* Enhance the availability and quality of habitat for, in particular<br />
** Bullhead (Cottus gobio) (increased diversity of hard bed, particularly pools during winter and riffle/fast glides during summer and increased large woody debris for, particularly, juveniles)<br />
** Brook lamprey (Lampetra planeri) (increased availability of well sorted, fine sediment in shaded, marginal areas with large woody debris for ammocoetes and gravel/sand dominated shallows <40 cm deep for spawning adults)<br />
** Salmon parr (Salmo salar) (increased availability of coarse substrate, with overhead cover and woody debris lodged in the channel)<br />
** Desmoulin’s whorl snail (Vertigo moulinsiana) in the marginal zone of the channel<br />
** The Ranunculus community as a result of increased heterogeneity in velocity and bed morphology<br />
<br />
==Success Criteria==<br />
<br />
In the bidding documents for the permits, there was a criteria value of spawning habitats. There was also the criterion to increase morphological diversity, but this was not quantified by a value<br />
<br />
==Site description==<br />
<br />
==Measures selection==<br />
<br />
Location Hale was divided in 7 reaches. No measures were planned for reach 1 and reach 7. At two locations (Reach 2 and 4) 30-40 meter spawning riffles were created using existing and imported gravels. The existing gravels are used to create a stable crest. Gravels are placed on top and below the crest of the riffle to provide a suitable depth for spawning. <br />
<br />
<br />
In two reaches (Reach 4 and 6) upstream current deflectors were constructed to create a varying flow and to narrow the channel. These deflectors are made of large tree limbs set at angles between 30° and 60° and are 12-15 meters in length. The tree limbs are secured to prevent washing away.<br />
<br />
<br />
Woody debris is added at all reaches (except reach 1 and 7). In reach 2, native trees were planted to serve as future source of woody debris. Temporary fencing is placed to protect the trees from graving by livestock. In the other reaches, trees were coppiced or pollarded to get woody debris in the stream. In reach 5, the woody debris was used to install a tree kicker.<br />
<br />
==Monitoring==<br />
<br />
''Pre-restoration monitoring''<br />
<br />
At location Hale, a rapid assessment survey was done during pre- and post-monitoring. The rapid assessment survey consists of a physical biotope survey where biotopes were mapped and a river corridor survey to assess vegetation. The assessment is based on expert judgment, although the method has possibilities to add qualitative and quantitative results of analysis undertaken for particular elements. The pre-monitoring effort was to record the hydro-morphological and biological conditions of the site before any measures where taken.<br />
<br />
''Post-restoration monitoring''<br />
<br />
The post-monitoring occurred two years later using the same monitoring techniques. The results are compared to see if the restoration measures had any effect on the site.<br />
<br />
==Expectations and Response==<br />
<br />
The positive results of the restoration measures mostly involve the expected increase of flow variability by the reshaping of the channel. The created riffles were expected to promote local sediment transport and flow variability which results in a change of substrate composition of the river bed from sand/silt dominated to gravel/pebbles dominated. Growth of Ranunculus and other aquatic plants should be increased on the riffles. The riffles also provide a suitable spawning habitat for salmon (S. salar) which would have positive results on the population size of this species. <br />
<br />
The planted trees would increase habitat for terrestrial invertebrates and nesting birds. Large woody debris deflectors at reach 6 would promote geomorphological processes like sedimentation of silt. Brook lamprey (L. planeri) should benefit from the increased habitat opportunities created by the woody debris. The improvement of the vegetation should develop habitat suitable for Desmoulin’s whorl snail (V. moulinsiana).<br />
<br />
‘’Ecological response’’<br />
Fish, macro-invertebrates and phytoplankton were not surveyed, so the effect of the restoration measures on these biological quality indicators is not known. Barble has been seen to be spawning on the riffles, but this was not an official part of the monitoring process.<br />
<br />
Vegetation<br />
<br />
The vegetation structure and species diversity appears to be similar to the pre-monitoring. Water crowfoot (Ranunculus penicillatus) occurs intermittently along the channel. No other macrophytes are found in the post-monitoring. In the pre-montoring, horned pondweed (Zannichellia palustris) was present in the river. <br />
<br />
The riparian buffer zone varies from narrow to non-existent in case of grasslands which support sheep and cattle grazing. Upstream broadleaved woodland is present on the left bank with sycamore (Acer pseudoplatanus) and ash (Fraxinus excelsior) with occasional willow (Salix sp.) and English oak (Quercus robur). On the left bank, reeds like reed sweet grass (Glyceria maxima), common reed (Phragmites australis) and reed canary grass (Phalaris arundinacea) are present with occasional hawthorn (Crataegus monogyna) and bramble (Rubus fruticosus agg.). Downstream, both banks have similar vegetation. Dominant species are reed sweet grass (G. maxima) and common nettle (Urtica dioica) with other species like yellow flag iris (Iris pseudacorus), reed canary grass (P. arundinacea), bramble (R. fruticosa), water mint (Mentha aquatic), great willow herb (Epilobium hirsutum), branched bur-reed (Sparganium erectum) and occasional alders (Alnus glutinosa).<br />
<br />
Hydro-morphological response<br />
<br />
The dominant physical biotope at the Hale site was glide. At the start of the last meander bend, a deep pool was observed. Upwelling was observed at two locations. It should be noted that the discharge and water levels were high and this could have obscured localised diversity created by the restoration measures. The two areas of upwelling can be related to the large riffle upstream of the first upwelling area and the woody debris deflectors within the second upwelling area. <br />
<br />
Due to the high water level during the post-monitoring, the influence of the restoration measures on the patterns of sediment deposition in the channel bed could not be assessed. Bank erosion at meander bends is reduced due to increased marginal vegetation and local exclusion of livestock by through fencing. <br />
<br />
Socio-economic response<br />
<br />
The impact of the measures on socio-economic aspects like flood protection are not monitored and therefore unknown. There was speculation that the increase in marginal vegetation cover is related to the sustained higher water levels in 2007 and 2008 at the time of the survey. The Hampshire Avon Catchment Flood Management Plan published in 2009 indicates that the area of Hale has sufficient flood risk management, but could be improved to cope with future climate change.<br />
<br />
==Cooperation==<br />
<br />
During the planning phase, the public was informed via public meetings and press releases in the newspapers and magazines. The stakeholders had to accept the concept design in the project bid and during the project there was constant contact with the stakeholders. Concerns or criticisms were investigated and the project changed when the criticisms were verified. At the end of the project a conference was held for all stakeholders and general public to show them the end results of the project in their area.<br />
<br />
==Funding==<br />
<br />
The total costs of the project were £1 million pounds. 40% of this total costs was paid for by the European Union via LIFE subsidies. The rest of the costs were paid for by the state, a water company and 2 wild life trusts.<br />

==General description==<br />
<br />
Meinerswijk is a floodplain situated in the centre of the city of Arnhem. The brick industry has had a big influence on the area by sand and clay extraction. In 1988 the municipality decided to develop Meinerswijk into a freely accessible nature area as part of Plan Ooievaar. The floodplain is an important recreational area for the city and it is a unique nature area in the center of a highly urbanized area. <br />
<br />
Meinerswijk has been chosen as one of the areas that have to be developed to improve the flood protection scheme described in the Room for the River plans. The river bend at Meinerswijk is a bottleneck for river flow due to the urban development in large parts of the original floodplain. Improving the possibilities for water retention during peak flows is essential to lower the water level near the city of Arnhem and further downstream during high water conditions.<br />
<br />
<br />
==Pressures and Drivers==<br />
<br />
Urbanization and industry have played a large role in the current look of Meinerwijk. For the brick industry clay and sand was extracted from the flood plain, creating deep pools. In the 70s some of these pools were filled up with garbage from the city. Currently, Meinerswijk is an important recreation area with elements of the historical IJssel line. The river itself has been channelized for navigation and has 3 large weirs downstream to create a regulated flow to increase the discharge in the IJssel. <br />
<br />
==Global objectives==<br />
<br />
The global objectives of the construction in Meinerswijk is to improve the distribution of flood discharge in the Waal, Nederrijn and IJssel and to preserve and improve the robust flood plain nature with low dynamic groundwater-fed pools and marshes from Meinerswijk to Bakenhof. <br />
<br />
<br />
==Specific objectives==<br />
<br />
The normative high water level of the Nederrijn should be reduced with 7 cm in 2015. <br />
<br />
For ecology no specific objectives were made. The current protected habitats had to be sustained.<br />
<br />
==Success Criteria==<br />
<br />
The criterion for flood protection is that the normative high water level of the Nederrijn should be reduced with 7 cm. This criterion was set up in the national Room for the River program and is therefore obligatory by law.<br />
<br />

<br />
[[File:Map Meinerswijk.JPG|600px|Image: 600 pixels]]<br />
<br />
==Measures==<br />
<br />
To reach the flood protection criteria, measures were taken to increase the flood retention capacities of Meinerswijk. In the figure above, each measure is showed by a number. The banks at the upstream part of Meinerswijk (1) are raised with 50 cm to compensate for the sedimentation caused by the redesign of the Noorderlijke Rijnkade (A). Between the John Frost Bridge and the ASM harbor (2), rubble used for bank fixation is removed to improve the discharge to the Green River during high water. The largest measure is the creation of a Green River (3), a side channel that connects to the main channel during high water. In normal discharge conditions, the Green River is fed by groundwater and creates a nice marsh/reed habitat for typical riverine species. To ensure proper discharge, the shrub vegetation is maintained by mowing and extensive grazing. A drainage ditch (4) is filled up and more shrubs are removed near the Uitweg (5) to improve the discharge of the Green River. A part of the summer levee (6) near the Plas van Bruil is lowered for quicker inundation. Further downstream, a permanent side channel is made (7) which is not connected to the Plas van Bruil. This side channel is an important site for recreation. Also the Sleuteldam, a cultural heritage, will be restored (8).<br />
<br />
<br />
==Monitoring==<br />
<br />
<br />
''Pre-restoration monitoring''<br />
<br />
A standard species survey for species of the birds/habitat directive and red list species has been carried out as part of the permits process.<br />
<br />
<br />
''Post-restoration monitoring''<br />
<br />
No post-restoration monitoring was planned in the project. Rijkswaterstaat will be responsible for maintaining the roughness by monitoring the vegetation. The ecological monitoring will probably be outsourced by the municipality.<br />
<br />
==Expectations and Response==<br />
<br />
The project will be finished in 2015, so an exact response on the measures cannot be given.<br />
<br />
''Ecology''<br />
<br />
It is expected that the ecological potential of the area will be increased. The Green River will create more groundwater dependent habitats which are essential for many species. Habitats that are already present will be preserved. Discharge into the floodplain at high water is improved which will benefit habitats and species that are dependent on more dynamic conditions created by flooding. <br />
<br />
''Flood Protection''<br />
<br />
The measures are designed to lower the normative high water level in the Nederrijn. It is therefore expected that the objective will be reached and that the people and properties near the Nederrijn are protected.<br />
<br />
''Recreation''<br />
<br />
The creation of more recreational infrastructure and the expected more attractive habitats will give a positive boost on recreation for the citizens of Arnhem.<br />
<br />
''Navigation''<br />
<br />
Some of the measures can have a negative impact on navigation, but this is compensated in other areas of the project area. Overall, it is expected that navigation will have no hindrance of the new situation in the floodplain<br />
<br />
<br />
==Cooperation==<br />
<br />
The project is carried out by Rijkswaterstaat in cooperation with Provincie Gelderland, Gemeente Arnhem, Waterschap Rivierenland and Staatsbosbeheer. GMB Civiel-Van Oord is the contractor.<br />
<br />
There is cooperation with stakeholders during the project process. The main stakeholders are internal stakeholders in Rijkswaterstaat, mainly other divisions that represent navigation. Also a cooperation of local residents, Vrienden van Meinerswijk, is involved in the plans via a participation process.<br />
<br />
The land of one of the bigger land owners in the area, the real estate company Phanos B.V., was avoided in the project because no agreement could be established.<br />
<br />
==Communication==<br />
<br />
Communication and participation with the local community is very important in this project and a lot of time and effort is invested to ensure a good communication. Bert Pijpers, the contact person, described the project area as an arena with 70000 onlookers on both sides. To communicate with the local stakeholders and general public, a participation process has been developed. First, a future vision of the area was developed together with the stakeholders. Direct contact was maintained by many consultation sessions and evening meetings where the stakeholders could give their opinion on the plans. The contractor was chosen because of their public friendly approach with much contact and direct action when problems arise. <br />
<br />
For further communication, a website is maintained with monthly news letters. There is also a small information center where everybody who is interested can get more information and the contractor organizes a monthly excursion for interested locals.<br />
<br />
Technical reports were publically available during the permit process, but the most recent versions are not easily available. The discussion to keep these documents available on the project website is currently ongoing.<br />
<br />
<br />
==Funding==<br />
<br />
The Meinerswijk project is part of the national Room for the River project, which has a total budget of 2.180 million Euro. The project Meinerswijk has a budget of 14 million Euro.<br />

THIS IS UNDER CONSTRUCTION<br />
<br />
==General information==<br />
The River Cole is a tributary of the Thames and flows from the spring near the town of Swindon and flows through the National Trust owned estate Coleshill until it reaches the Thames. <br />
<br />
==Drivers and Pressures==<br />
Historical management has deteriorated the ecological value of the Cole. The river was straightened for more efficient flow for water mills and later enlarged to prevent flooding of agricultural lands in the original floodplain. The connection between the floodplain and river has been lost and nearby sewage treatment plants cause organic pollution. <br />
<br />
The Cole demonstration project was part of the River Demonstration Project together with the river Skerne and river Brede projects. This collaboration between British and Danish water managers tried to apply state-of-the-art restoration techniques and to demonstrate these projects to a wider audience of European water managers.<br />
<br />
==Global objectives==<br />
The global objective of the demonstration project consists of three goals:<br />
*Restoration of river and floodplain in terms of physical features, flood storage, habitat diversity and visual appearance. <br />
*Application of innovative restoration techniques and best management practice, within a sustainable agricultural system.<br />
*Furthering of knowledge and understanding of river restoration by monitoring to a very high degree, and by practical demonstration of the results.<br />
<br />
==Specific objectives==<br />
<br />
There were no specific goals for indicators in this project. Because it was the first project of its kind, the focus was more on achieving general social and ecological success.<br />
<br />
==Success Criteria==<br />
<br />
Because the focus of the project was more on achieving general social and ecological success, no strict success criteria for indicators were used.<br />
<br />
==Measures==<br />
To restore the river, a historical buried course was excavated. This small meandering channel had more natural bed and bank structures. This new restored course was attached to the existing old course. The mill leat was preserved with intentions to restore the mill. Downstream of the mill, the bed was raised and the channel was made smaller. A few backwater pools were kept and the mature riverside trees were spared. By making the stream less deep and smaller, the hydrological connection with the floodplains improved and the flood frequency increased.<br />
<br />
[[File:Cole_measures.JPG]]<br />
<br />
==Monitoring==<br />
<br />
''Pre-restoration monitoring''<br />
<br />
Before restoration started, several indicators were monitored to see what the reference situation is for post-restoration monitoring.<br />
<br />
*Ecology<br />
**River channel vegetation was monitored qualitatively by assessing the number of species found per 500 meter channel length. <br />
**Aquatic macro-invertebrates were monitored by assessing the species richness<br />
**Fish were monitored by assessing the grams biomass per m2, fish density and species richness. <br />
**Birds were monitored by assessing the assemblage of breeding birds and abundance<br />
<br />
*Hydro-morphology<br />
**Geomorphological monitoring was carried out by mapping channel cross sections and physical habitat mapping.<br />
**The water quality monitoring was focused on suspended sediment concentration and concentration of nitrogen (total oxidized nitrogen) and phosphorus (soluble reactive phosphorous) compounds<br />
<br />
*Flood protection<br />
**The hydrological regime was monitored by modeling the flood frequency.<br />
<br />
*Social-economic factors<br />
**Economic benefits for six categories (water quality, amenity, fisheries, agriculture, flood defense and recreation) were calculated.<br />
<br />
<br />
''Post-restoration monitoring''<br />
<br />
The post-restoration monitoring consists of two methods. First, the same indicators and monitoring techniques used in the pre-restoration monitoring are repeated for post-restoration monitoring. One exception is the assessment of public perception via a questionnaire, which was only done after restoration. <br />
<br />
The other method is comparing the data to another location, in this case downstream of the river. This was done to assess the impact of the restoration on the downstream areas, but it can also be used to compare the results of the restoration between the restored site and a control site.<br />
<br />
==Expectations and Response==<br />
It was expected that the new meandering channel would provide better habitat opportunities for river species. The hydro-morphology and flood frequency in the floodplain would improve because of the more natural channel dimension. The full results can be found in the final report: The effects of river restoration on the R. Cole and R. Skerne demonstration sites: Final Report, River Restoration Centre March 1999<br />
<br />
<br />
''Ecology''<br />
<br />
'''Macrophyte''' species richness increased immediately after restoration. Marginal emergent plant species richness increased significantly, but submerged aquatic plants showed a less immediate effect. The control site downstream was not affected by the restoration works. <br />
<br />
<br />
The new channel was quickly recolonized by '''macro-invertebrates''', but the more uncommon taxa related to more mature habitats were not present yet after 1 year. Two new species were found in the restored Cole, one stonefly (Leuctra geniculata) and a caddis fly (Athripsodes albifrons)<br />
<br />
<br />
'''Fish''' biomass and density returned to pre-restoration levels, however the highest measured biomasses and densities were found just downstream of the restored reach. The species richness remained unchanged.<br />
<br />
<br />
For '''Birds''', the number of breeding wetland species did not increase 1 year after restoration. The abundance of Yellow Wagtails (Motacilla flava) increased significant. Casual inspection suggested that there was little change 2 years after restoration.<br />
<br />
<br />
''Hydro-morphology''<br />
<br />
The river length was increased by 30%. The cross-sectional area was considerably smaller and less deep. The number of natural in-channel features like riffles had increased after restoration. <br />
<br />
The suspended sediment concentration increased after the restoration works compared to upstream control sites. The nutrient concentrations showed no changes.<br />
<br />
<br />
''Flood protection''<br />
<br />
The restoration measures recreated a more natural flooding regime. Prior to restoration, flooding in the Cole was infrequent, but after restoration 10% of the floodplain is influenced by the more regular flooding regime of 17 days per year. <br />
<br />
<br />
''Social-economic factors''<br />
<br />
'''Public perception''' was measured via a questionnaire and 53% of the replyers in Coleshill mostly approved the measures while 17% strongly approved.<br />
<br />
The '''economic benefits''' of the restoration over a 25 year period was estimated to range from £38,000 to £347,000, mostly from recreation and conservation benefits.<br />
<br />
==Cooperation==<br />
The demonstration project in total was a collaboration between water managers in the UK and Denmark. However, the restoration itself was carried out by national, regional and local partners of both governmental and private sectors. The partners both worked on the river Cole and Skerne (Holmes et al., 1998). The project partners of the river Cole were:<br />
<br />
*National Rivers Authority<br />
*English Nature<br />
*Darlington Borough Council<br />
*Countryside Commission<br />
*Northumbrian Water<br />
*Department of Agriculture N. Ireland<br />
*River Restoration Centre<br />
*National Trust<br />
*Scottish Natural Heritage<br />
<br />
==Communication==<br />
<br />
The communication strategy was limited. Only the land owners were consulted on the project. The local community of a nearby village was not involved in the project. Later evaluation for public perception showed the local community felt left out of the project and a lack of interest in the overal project.<br />
<br />
==Funding==<br />
The total budget of the project submitted to the EU-LIFE project was € 1,758,621.29, because Denmark was the leading partner. The UK budget was initially set at £850,000, but increased interest and support let the total project budget grow to almost £1 million.<br />

THIS IS UNDER CONSTRUCTION<br />
<br />
==General information==<br />
The River Cole is a tributary of the Thames and flows from the spring near the town of Swindon and flows through the National Trust owned estate Coleshill until it reaches the Thames. <br />
<br />
==Drivers and Pressures==<br />
Historical management has deteriorated the ecological value of the Cole. The river was straightened for more efficient flow for water mills and later enlarged to prevent flooding of agricultural lands in the original floodplain. The connection between the floodplain and river has been lost and nearby sewage treatment plants cause organic pollution. <br />
<br />
The Cole demonstration project was part of the River Demonstration Project together with the river Skerne and river Brede projects. This collaboration between British and Danish water managers tried to apply state-of-the-art restoration techniques and to demonstrate these projects to a wider audience of European water managers.<br />
<br />
==Global objectives==<br />
The global objective of the demonstration project consists of three goals:<br />
*Restoration of river and floodplain in terms of physical features, flood storage, habitat diversity and visual appearance. <br />
*Application of innovative restoration techniques and best management practice, within a sustainable agricultural system.<br />
*Furthering of knowledge and understanding of river restoration by monitoring to a very high degree, and by practical demonstration of the results.<br />
<br />
==Specific objectives==<br />
<br />
There were no specific goals for indicators in this project. Because it was the first project of its kind, the focus was more on achieving general social and ecological success.<br />
<br />
==Success Criteria==<br />
No success criteria were found in the available documents<br />
<br />
==Measures==<br />
To restore the river, a historical buried course was excavated. This small meandering channel had more natural bed and bank structures. This new restored course was attached to the existing old course. The mill leat was preserved with intentions to restore the mill. Downstream of the mill, the bed was raised and the channel was made smaller. A few backwater pools were kept and the mature riverside trees were spared. By making the stream less deep and smaller, the hydrological connection with the floodplains improved and the flood frequency increased.<br />
<br />
[[File:Cole_measures.JPG]]<br />
<br />
==Monitoring==<br />
<br />
''Pre-restoration monitoring''<br />
<br />
Before restoration started, several indicators were monitored to see what the reference situation is for post-restoration monitoring.<br />
<br />
*Ecology<br />
**River channel vegetation was monitored qualitatively by assessing the number of species found per 500 meter channel length. <br />
**Aquatic macro-invertebrates were monitored by assessing the species richness<br />
**Fish were monitored by assessing the grams biomass per m2, fish density and species richness. <br />
**Birds were monitored by assessing the assemblage of breeding birds and abundance<br />
<br />
*Hydro-morphology<br />
**Geomorphological monitoring was carried out by mapping channel cross sections and physical habitat mapping.<br />
**The water quality monitoring was focused on suspended sediment concentration and concentration of nitrogen (total oxidized nitrogen) and phosphorus (soluble reactive phosphorous) compounds<br />
<br />
*Flood protection<br />
**The hydrological regime was monitored by modeling the flood frequency.<br />
<br />
*Social-economic factors<br />
**Economic benefits for six categories (water quality, amenity, fisheries, agriculture, flood defense and recreation) were calculated.<br />
<br />
<br />
''Post-restoration monitoring''<br />
<br />
The post-restoration monitoring consists of two methods. First, the same indicators and monitoring techniques used in the pre-restoration monitoring are repeated for post-restoration monitoring. One exception is the assessment of public perception via a questionnaire, which was only done after restoration. <br />
<br />
The other method is comparing the data to another location, in this case downstream of the river. This was done to assess the impact of the restoration on the downstream areas, but it can also be used to compare the results of the restoration between the restored site and a control site.<br />
<br />
==Expectations and Response==<br />
It was expected that the new meandering channel would provide better habitat opportunities for river species. The hydro-morphology and flood frequency in the floodplain would improve because of the more natural channel dimension. The full results can be found in the final report: The effects of river restoration on the R. Cole and R. Skerne demonstration sites: Final Report, River Restoration Centre March 1999<br />
<br />
<br />
''Ecology''<br />
<br />
'''Macrophyte''' species richness increased immediately after restoration. Marginal emergent plant species richness increased significantly, but submerged aquatic plants showed a less immediate effect. The control site downstream was not affected by the restoration works. <br />
<br />
<br />
The new channel was quickly recolonized by '''macro-invertebrates''', but the more uncommon taxa related to more mature habitats were not present yet after 1 year. Two new species were found in the restored Cole, one stonefly (Leuctra geniculata) and a caddis fly (Athripsodes albifrons)<br />
<br />
<br />
'''Fish''' biomass and density returned to pre-restoration levels, however the highest measured biomasses and densities were found just downstream of the restored reach. The species richness remained unchanged.<br />
<br />
<br />
For '''Birds''', the number of breeding wetland species did not increase 1 year after restoration. The abundance of Yellow Wagtails (Motacilla flava) increased significant. Casual inspection suggested that there was little change 2 years after restoration.<br />
<br />
<br />
''Hydro-morphology''<br />
<br />
The river length was increased by 30%. The cross-sectional area was considerably smaller and less deep. The number of natural in-channel features like riffles had increased after restoration. <br />
<br />
The suspended sediment concentration increased after the restoration works compared to upstream control sites. The nutrient concentrations showed no changes.<br />
<br />
<br />
''Flood protection''<br />
<br />
The restoration measures recreated a more natural flooding regime. Prior to restoration, flooding in the Cole was infrequent, but after restoration 10% of the floodplain is influenced by the more regular flooding regime of 17 days per year. <br />
<br />
<br />
''Social-economic factors''<br />
<br />
'''Public perception''' was measured via a questionnaire and 53% of the replyers in Coleshill mostly approved the measures while 17% strongly approved.<br />
<br />
The '''economic benefits''' of the restoration over a 25 year period was estimated to range from £38,000 to £347,000, mostly from recreation and conservation benefits.<br />
<br />
==Cooperation==<br />
The demonstration project in total was a collaboration between water managers in the UK and Denmark. However, the restoration itself was carried out by national, regional and local partners of both governmental and private sectors. The partners both worked on the river Cole and Skerne (Holmes et al., 1998). The project partners of the river Cole were:<br />
<br />
*National Rivers Authority<br />
*English Nature<br />
*Darlington Borough Council<br />
*Countryside Commission<br />
*Northumbrian Water<br />
*Department of Agriculture N. Ireland<br />
*River Restoration Centre<br />
*National Trust<br />
*Scottish Natural Heritage<br />
<br />
==Communication==<br />
<br />
The communication strategy was limited. Only the land owners were consulted on the project. The local community of a nearby village was not involved in the project. Later evaluation for public perception showed the local community felt left out of the project and a lack of interest in the overal project.<br />
<br />
==Funding==<br />
The total budget of the project submitted to the EU-LIFE project was € 1,758,621.29, because Denmark was the leading partner. The UK budget was initially set at £850,000, but increased interest and support let the total project budget grow to almost £1 million.<br />
<br />
The project budget for both the Skerne and Cole was divided in 4 elements, each with a set amount of budget.<br />
*£350,000 for construction contracts<br />
*£200,000 for pre- and post-restoration monitoring studies<br />
*£190,000 for management, promotion, compensations and administration<br />
*+/- £190,000 for survey, design, contract documentation and site supervision <br />
<br />
<br />
The EU contribution to the total project was € 749,172.67.<br />

<br />
==General information==<br />
<br />
The IJssel is one of the large branches of the Rhine. The river starts at Westervoort, near the city of Arnhem and ends in Lake IJssel. The length of the IJssel is 125 km and the average discharge is 340m3/s.<br />
<br />
==Pressures and Drivers==<br />
<br />
In the 18th century, the Pannerdensch canal was dug to facilitate year-round shipping. By law, the river minimally receives 1/9th of the total Rhine water. River bends were cut off to channelize the river and the newly acquired flood plains were cut off from the rivers influence by dikes. To keep a sustainable shipping depth, groins were constructed. In the remaining flood plains, gravel and sand abstraction created deep, isolated gravel pits with little ecological value. These measures have lead to a deterioration of typical river habitats and species.<br />
<br />
<br />
Project IJsseluiterwaarden-Olst is part of the national plan ‘Room for the River’ and has been in development since 2005. The project first started as ecological restoration project to improve the EHS (Ecologische Hoofd Structuur), but later the project was included in the Room for the River plan giving it the main goal of lowering the expected high water level in 2015.<br />
<br />
==Global objectives==<br />
<br />
With expected climate change, the current flood defense structure cannot guarantee the legal norms. Therefore, measures to give the river more room (Kernbesluit Ruimte voor de Rivier) are planned for the flood plains in the IJssel. IJsseluiterwaarden Olst is one of these projects. The measures also incorporate more room for riverine habitats in the flood plains.<br />
<br />
==Specific objectives==<br />
<br />
''Flood protection''<br />
<br />
One of the main goals of the IJsseluiterwaarden Olst project is lowering the normative high water level with 7.8 cm in 2015. <br />
<br />
<br />
''Ecological objectives''<br />
<br />
The specific ecological goals are mainly focused on preserving and creating possibilities for typical river habitat types. These types are according to the Dutch habitat list.<br />
<br />
* Preserve and improve conditions for target fish species of the Habitat Directive<br />
** H1134 European bitterling (Rhodeus sericeus amarus)<br />
** H1145 European Weather Loach (Misgurnus fossilis)<br />
** H1149 Spined Loach (Cobitis taenia)<br />
** H1163 European Bullhead (Cottus gobio)<br />
<br />
*Preserve and improve conditions for target species of the Habitat and Birds Directive<br />
** H1166 Northern crested newt (Triturus cristatus)<br />
** Migrating birds<br />
** Breeding birds<br />
<br />
*Preserve and improve habitat types from the Habitat Directive, namely <br />
** H3270 Slikkige Rivieroevers<br />
** H3150 Meren met Krabbenscheer<br />
** H6120 Stroomdalgrasland<br />
** H6430_A Ruigten en zomen<br />
** H6510_A Glanshaver- en vossenstaarthooilanden<br />
** H91F0 Zachthoutooibos<br />
** H6430C Hardhoutooibos<br />
<br />
<br />
==Success Criteria==<br />
<br />
For flood protection, the criterion that has to be reached is a decrease in normative high water level with 7.8 cm by 2015. <br />
<br />
For the ecological status, no clear criteria are mentioned.<br />
<br />
==Site description==<br />
<br />
[[File:Map IJsseluiterwaarden Olst.JPG ]]<br />
<br />
==Measures selection==<br />
<br />
The measures in the floodplain are carried out in three project areas, namely Welsumerwaard, De Roetwaarden and De Enk/De Zaaij.<br />
<br />
''Welsumerwaard''<br />
<br />
In this area, a side channel is made that consists of an isolated channel and a channel that is connected to the IJssel with a threshold of NAP +3.8 m, separated by the road to the local ferry. The area will be maintained by mowing 4x a year and extensive grazing. <br />
<br />
''De Roetwaarden''<br />
<br />
In the Roetwaarden, current inlet in the upstream sand pit is rearranged to accommodate better discharge capacity during high water and the current threshold of NAP +3.6 m is kept. A levee with trees is removed to improve the discharge. The sand pits downstream are connected to the IJssel using a regulated weir which to protect the hinterlands from water damage during high water and drought during normal water. The area is maintained by mowing.<br />
<br />
''De Enk/De Zaaij''<br />
<br />
In De Zaaij, no excavation works are planned and the current land use is mostly maintained. Closer to the Duursche Waarden, floodplain forest is allowed to develop. In the Enk, one side channel is planned, in extension of the side channel in the Roetwaarden. The side channel is 100 meters wide and has a maximum depth of NAP – 2.5 m. The surrounding land is lowered to NAP + 3.0 m and slowly increases to NAP + 5 m at the river dune of Fortmond. This creates a gradual variation in elevation gradient which is characteristic for the landscape.<br />
<br />
==Monitoring==<br />
<br />
''Pre-monitoring''<br />
<br />
For the Environmental Impact Assessment, the current state of the ecological, hydro-morphological and social-economic factors had to be determined. The exact method of acquiring the monitoring data is unknown.<br />
<br />
<br />
''Post-monitoring''<br />
<br />
Monitoring will mostly be targeted at hydro-morphological processes in the side channel, vegetation development and effects of recreation on nature. A monitoring plan for these three aspects is proposed. For vegetation development, the monitoring should first be yearly to assess how the pioneer vegetation responds and how much this affects the roughness of the floodplain. Afterwards, monitoring every six years is proposed. <br />
<br />
==Expectations==<br />
<br />
In the Environmental Impact Assessment, the impact of the measures on flood protection, hydro-morphology, ecology and social-economic factors is assessed. A summery is given here, for further details please check the document. <br />
<br />
<br />
''Ecological response''<br />
<br />
The ecological response is difficult to determine. The planned measures create 16.3 ha of side channels which increase the opportunities for habitats in and near open water. However, in large part of the current agricultural activities remain and areas are maintained by mowing. This reduces the opportunities for dynamic processes and succession. In total, 83 ha of new nature are created, but the effects the different habitattypes currently present in the area is limited. Only a positive increase of riverine forest (zachthoutooibos H91E0A) is expected. For species in the Habitat and Birds directive, neutral or positive effects are expected. Significant positive impacts are expected for Kingfisher, other fish eating birds and duck species of subfamily Aythyinae and Anatini. A slight positive impact is expected for European Bitterling (R. sericeus amarus), River Clubtail (Gomphus flavipes) and Spined Loach (C. taenia). A slight negative effect is expected for grass eating water birds, because of loss of pastures to nature development.<br />
<br />
<br />
''Hydro-morphological response''<br />
<br />
Because of the extra side channels, the main channel suffers from sedimentation between kmr 958 and 960. The total dredging volume is 6100 m3. <br />
<br />
<br />
''Flood protection response''<br />
<br />
The planned measures in combination with the desired vegetation roughness lead to a lowering of the normative high water level with 8.24 cm at river km 956.5. This leaves a 0.4 cm maintenance zone where extra vegetation development can be allowed. Downstream of the planning area, the water level increases with a maximum of 0.5 cm at river km 962.6, near the Duursche Waarden. <br />
<br />
<br />
''Social-economic response''<br />
<br />
<br />
Navigation<br />
<br />
During high or low water, transverse flows can occur when water flows between the main channel and side channels. These flows have a sudden negative effect on ships and can lead to more accidents and decrease in speed. The guideline for the flow speed is 0.15 m/s, but in some places this guideline is passed. The river authority (Rijkswaterstaat) has to assess these effects and determine further action. <br />
<br />
<br />
Agriculture<br />
<br />
To make new nature areas possible, 85 ha of agricultural land is lost, but in most of the project area the current agricultural land use can be continued. <br />
<br />
<br />
Recreation<br />
<br />
The new nature areas will be accessible for recreation. New cycling and walking paths as well as a bridge over the new side channel in De Enk will be made to further improve the recreational infrastructure. This will lead to a slight positive effect on recreation in the area.<br />
<br />
<br />
Landscape and Cultural values<br />
<br />
The measures should not have a negative effect on the typical IJssel landscape morphology. Side channels are a normal part of this landscape type, but it replaces the historical-cultural landscape structure for agriculture. Digging in the floodplains can have devastating effects on the archeological value of the area, but the exact loss of value still has to be determined by further research. <br />

==Success Criteria==<br />
<br />
For flood protection, the criterion that has to be reached is a decrease in normative high water level with 7.8 cm by 2015. <br />
<br />
For the ecological status, no clear criteria are mentioned.<br />
<br />
==Site description==<br />
<br />
==Measures selection==<br />
<br />
The measures in the floodplain are carried out in three project areas, namely Welsumerwaard, De Roetwaarden and De Enk/De Zaaij.<br />
<br />
''Welsumerwaard''<br />
<br />
In this area, a side channel is made that consists of an isolated channel and a channel that is connected to the IJssel with a threshold of NAP +3.8 m, separated by the road to the local ferry. The area will be maintained by mowing 4x a year and extensive grazing. <br />
<br />
''De Roetwaarden''<br />
<br />
In the Roetwaarden, current inlet in the upstream sand pit is rearranged to accommodate better discharge capacity during high water and the current threshold of NAP +3.6 m is kept. A levee with trees is removed to improve the discharge. The sand pits downstream are connected to the IJssel using a regulated weir which to protect the hinterlands from water damage during high water and drought during normal water. The area is maintained by mowing.<br />
<br />
''De Enk/De Zaaij''<br />
<br />
In De Zaaij, no excavation works are planned and the current land use is mostly maintained. Closer to the Duursche Waarden, floodplain forest is allowed to develop. In the Enk, one side channel is planned, in extension of the side channel in the Roetwaarden. The side channel is 100 meters wide and has a maximum depth of NAP – 2.5 m. The surrounding land is lowered to NAP + 3.0 m and slowly increases to NAP + 5 m at the river dune of Fortmond. This creates a gradual variation in elevation gradient which is characteristic for the landscape.<br />
<br />
==Monitoring==<br />
<br />
''Pre-monitoring''<br />
<br />
For the Environmental Impact Assessment, the current state of the ecological, hydro-morphological and social-economic factors had to be determined. The exact method of acquiring the monitoring data is unknown.<br />
<br />
<br />
''Post-monitoring''<br />
<br />
Monitoring will mostly be targeted at hydro-morphological processes in the side channel, vegetation development and effects of recreation on nature. A monitoring plan for these three aspects is proposed. For vegetation development, the monitoring should first be yearly to assess how the pioneer vegetation responds and how much this affects the roughness of the floodplain. Afterwards, monitoring every six years is proposed. <br />
<br />
==Expectations==<br />
<br />
In the Environmental Impact Assessment, the impact of the measures on flood protection, hydro-morphology, ecology and social-economic factors is assessed. A summery is given here, for further details please check the document. <br />
<br />
<br />
''Ecological response''<br />
<br />
The ecological response is difficult to determine. The planned measures create 16.3 ha of side channels which increase the opportunities for habitats in and near open water. However, in large part of the current agricultural activities remain and areas are maintained by mowing. This reduces the opportunities for dynamic processes and succession. In total, 83 ha of new nature are created, but the effects the different habitattypes currently present in the area is limited. Only a positive increase of riverine forest (zachthoutooibos H91E0A) is expected. For species in the Habitat and Birds directive, neutral or positive effects are expected. Significant positive impacts are expected for Kingfisher, other fish eating birds and duck species of subfamily Aythyinae and Anatini. A slight positive impact is expected for European Bitterling (R. sericeus amarus), River Clubtail (Gomphus flavipes) and Spined Loach (C. taenia). A slight negative effect is expected for grass eating water birds, because of loss of pastures to nature development.<br />
<br />
<br />
''Hydro-morphological response''<br />
<br />
Because of the extra side channels, the main channel suffers from sedimentation between kmr 958 and 960. The total dredging volume is 6100 m3. <br />
<br />
<br />
''Flood protection response''<br />
<br />
The planned measures in combination with the desired vegetation roughness lead to a lowering of the normative high water level with 8.24 cm at river km 956.5. This leaves a 0.4 cm maintenance zone where extra vegetation development can be allowed. Downstream of the planning area, the water level increases with a maximum of 0.5 cm at river km 962.6, near the Duursche Waarden. <br />
<br />
<br />
''Social-economic response''<br />
<br />
<br />
Navigation<br />
<br />
During high or low water, transverse flows can occur when water flows between the main channel and side channels. These flows have a sudden negative effect on ships and can lead to more accidents and decrease in speed. The guideline for the flow speed is 0.15 m/s, but in some places this guideline is passed. The river authority (Rijkswaterstaat) has to assess these effects and determine further action. <br />
<br />
<br />
Agriculture<br />
<br />
To make new nature areas possible, 85 ha of agricultural land is lost, but in most of the project area the current agricultural land use can be continued. <br />
<br />
<br />
Recreation<br />
<br />
The new nature areas will be accessible for recreation. New cycling and walking paths as well as a bridge over the new side channel in De Enk will be made to further improve the recreational infrastructure. This will lead to a slight positive effect on recreation in the area.<br />
<br />
<br />
Landscape and Cultural values<br />
<br />
The measures should not have a negative effect on the typical IJssel landscape morphology. Side channels are a normal part of this landscape type, but it replaces the historical-cultural landscape structure for agriculture. Digging in the floodplains can have devastating effects on the archeological value of the area, but the exact loss of value still has to be determined by further research. <br />

==General information==<br />
<br />
The IJssel is one of the large branches of the Rhine. The river starts at Westervoort, near the city of Arnhem and ends in Lake IJssel. The length of the IJssel is 125 km and the average discharge is 340m3/s.<br />
<br />
==Pressures and Drivers==<br />
<br />
In the 18th century, the Pannerdensch canal was dug to facilitate year-round shipping. By law, the river minimally receives 1/9th of the total Rhine water. River bends were cut off to channelize the river and the newly acquired flood plains were cut off from the rivers influence by dikes. To keep a sustainable shipping depth, groins were constructed. In the remaining flood plains, gravel and sand abstraction created deep, isolated gravel pits with little ecological value. These measures have lead to a deterioration of typical river habitats and species.<br />
<br />
<br />
Project IJsseluiterwaarden-Olst is part of the national plan ‘Room for the River’ and has been in development since 2005. The project first started as ecological restoration project to improve the EHS (Ecologische Hoofd Structuur), but later the project was included in the Room for the River plan giving it the main goal of lowering the expected high water level in 2015.<br />
<br />
==Global objectives==<br />
<br />
With expected climate change, the current flood defense structure cannot guarantee the legal norms. Therefore, measures to give the river more room (Kernbesluit Ruimte voor de Rivier) are planned for the flood plains in the IJssel. IJsseluiterwaarden Olst is one of these projects. The measures also incorporate more room for riverine habitats in the flood plains.<br />
<br />
==Specific objectives==<br />
<br />
''Flood protection''<br />
<br />
One of the main goals of the IJsseluiterwaarden Olst project is lowering the normative high water level with 7.8 cm in 2015. <br />
<br />
<br />
''Ecological objectives''<br />
<br />
The specific ecological goals are mainly focused on preserving and creating possibilities for typical river habitat types. These types are according to the Dutch habitat list.<br />
<br />
* Preserve and improve conditions for target fish species of the Habitat Directive<br />
** H1134 European bitterling (Rhodeus sericeus amarus)<br />
** H1145 European Weather Loach (Misgurnus fossilis)<br />
** H1149 Spined Loach (Cobitis taenia)<br />
** H1163 European Bullhead (Cottus gobio)<br />
<br />
*Preserve and improve conditions for target species of the Habitat and Birds Directive<br />
** H1166 Northern crested newt (Triturus cristatus)<br />
** Migrating birds<br />
** Breeding birds<br />
<br />
*Preserve and improve habitat types from the Habitat Directive, namely <br />
** H3270 Slikkige Rivieroevers<br />
** H3150 Meren met Krabbenscheer<br />
** H6120 Stroomdalgrasland<br />
** H6430_A Ruigten en zomen<br />

The new nature areas will be accessible for recreation. New cycling and walking paths as well as a bridge over the new side channel in De Enk will be made to further improve the recreational infrastructure. This will lead to a slight positive effect on recreation in the area.<br />
<br />
<br />
Landscape and Cultural values<br />
<br />
The measures should not have a negative effect on the typical IJssel landscape morphology. Side channels are a normal part of this landscape type, but it replaces the historical-cultural landscape structure for agriculture. Digging in the floodplains can have devastating effects on the archeological value of the area, but the exact loss of value still has to be determined by further research. <br />

==General description==<br />
<br />
The Grote Nete is a 44 kilometre long river that has its source north east of the village Hechtel and confluences with the Kleine Nete before ending in the river Scheldt. <br />
<br />
<br />
The restoration plan of the Grote Nete is part of the large Sigmaplan, a flood defence plan covering a large part of Flanders. With the increased risk of substantial flooding due to climate change, the Sigmaplan was developed to implement flood reduction measures combined with improving the ecological status of the floodplains. In this project, ecology and flood protection are equal in priority. The restoration plan is divided in three subprojects, with Tussen Hellebrug en Herenbossen as largest project. The two other projects are Ter Borght – de Merode and Het Zammelsbroek.<br />
<br />
==Pressures and Drivers==<br />
<br />
The Grote Nete has been normalised to improve the discharge and to gain extra land for agriculture and urbanization. Levees were constructed to protect the newly gained lands from flooding, but they have cut off the floodplain from the river. These pressures have deteriorated the riverine ecosystem and wetlands near the river. <br />
<br />
==Global objectives==<br />
<br />
The global objective of the project area Tussen Hellebrug en Herenbossen consists of three subgoals:<br />
<br />
* Create 650 ha of new wetland nature<br />
* Retain more water temporarily during flooding events<br />
* No chance of the surface water and groundwater level outside of the project area<br />
<br />
==Specific objectives==<br />
<br />
In the Sigmaplan, the specific objectives for ecology are based on several target species of bird and mammal. The habitats restored and/or created by the measures have to be suitable to facilitate breeding pairs or viable populations. Other target species, mainly fish species, are expected to improve because they live in the required habitat of the main target species.<br />
<br />
The main target species consist of:<br />
<br />
* Eurasian Bittern (Botaurus stellaris)<br />
* Corn crake (Crex crex)<br />
* Spotted crake (Porzana porzana)<br />
* Beaver (Castor fiber)<br />
* Eurasian otter (Lutra lutra)<br />
<br />
The ‘sub’ target species that are expected to benefit from the main target species are:<br />
<br />
* Little Bittern (Ixobrychus minutus)<br />
* Savi’s Warbler (Locustella luscinioides)<br />
* Winchat (Saxicola rubetra)<br />
* Bearded Reedling (Panurus biarmicus)<br />
* Garganey (Anas querquedula)<br />
* European River Lamprey (Lampetra fluviatilis) <br />
* Twait Shad (Alosa fallax)<br />
* Allis Shad (Alosa alosa)<br />
* Smelt (Osmerus eperlanus)<br />
* European Eel (Anguila anguila)<br />
* European Weather Loach (Misgurnus fossilis)<br />
* Spined Loach (Cobitis taenia)<br />
* European Bitterling (Rhodeus amarus)<br />
* European Bullhead (Cottus perifretum)<br />
* Wels Catfish (Silurus glanis)<br />
<br />
<br />
==Success Criteria==<br />
<br />
The criteria for success are all related to the main target species. The created habitat has to facilitate:<br />
<br />
* 6-7 breeding pairs of Eurasian Bittern<br />
* 15 – 19 breeding pairs of Corn crake<br />
* 13 – 16 breeding pairs of Spotted Crake<br />
* Several families of Beaver<br />
* Several individuals of Eurasian otter<br />
* Viable core populations of European river lamprey (Lampetra fluviatilis), twait shad (Alosa fallax), Allis shad (Alosa alosa), smelt (Osmerus eperlanus), European eel (Anguila anguila), European weather loach (Misgurnus fossilis), Spined loach (Cobitis taenia), European bitterling (Rhodeus amarus), European bullhead (Cottus perifretum) and Wels catfish (Silurus glanis)<br />

<br />
==Measures selection==<br />
<br />
To reconnect the floodplains with the river, the summer dikes are locally lowered and in 14 stretches the main channel is made shallower. This increases the groundwater level to improve the abiotic circumstances in the floodplain. The thresholds that are placed to make the channel shallower will be designed to be a spawning ground for fish. In the floodplain, agricultural or recreational infrastructure and exotic species are removed and converted into wetlands and backwaters. Where possible, side channels that are now blocked by weirs will be made open to make fish migration possible. Old meanders and backwaters are restored to function as habitat. To protect the properties and people outside of the project area, the winter dikes are strengthened. The complete list with measures of all sub-areas are described in the Natuurontwikkelingsplan Sigmaplan – Inrichting Grote Nete versie 2.<br />
<br />
==Monitoring==<br />
<br />
''Pre-restoration monitoring''<br />
<br />
A basic baseline study has been preformed to determine what habitats and target species are present. The hydrological baseline for ground- and surface water has been measured and modelled.<br />
<br />
<br />
''Post-restoration monitoring''<br />
<br />
When the project is finished, continuous monitoring of ground- and surface water is conducted. Monitoring programs to assess the development of the preferred biotopes and species of fish, birds and macro-invertebrates are planned. The exact time scale and planning is still in progress.<br />
<br />
<br />
==Expectations and Response==<br />
<br />
The measures will improve the ecological status of the Grote Nete valley. Wetlands will return and improve in quality due to the higher groundwater level in the project area. The valley will have more room for water retention during high water periods and the hydrology of areas outside of the project area will not be affected. Municipalities see opportunities for recreation, since the natural areas will be more attractive for walking and cycling, but recreation will be limited in the project area to keep disturbances to the habitats limited. 200 hectares of agricultural lands have to be removed, but the negative impact has been limited to a minimum by cooperation with the farmers to design plans that affect as little land as possible.<br />
<br />
<br />
As the project is in progress in the Environment Impact Assessment phase, no responses on the measures can be described.<br />
<br />
<br />
==Cooperation==<br />
<br />
Cooperation with stakeholders is an important pillar in the Sigmaplan. In the planning phase, a wide variety of experts, for example ecologists, landscape architects and social scientists are involved in the plan making. Representatives of the local community and land users are also part of the work group as experts to give locals the opportunity to participate in the plan making. Issues and complaints from stakeholders are resolved on individual level. The stakeholders are also engaged in the implementation phase in structural meetings. <br />
<br />
==Communication==<br />
<br />
Cooperation and community engagement is dependant on a good communication strategy. The Sigmaplan has an elaborate communication strategy to keep the local community informed on the project progress and to invite them to information markets where they can also discuss the plans. Newsletters are distributed to the local community and at certain moments in the legal procedure of the project, the project plans can be viewed and remarks can be given. <br />
<br />
<br />
In the later implementation phase, the newsletters function as information source of the projects. Structural meetings with the work group remain to discuss the progress.<br />
<br />
<br />
==Funding==<br />
<br />
The Sigmaplan is a national project and is funded by the National government. <br />
