==Key features of the case study==
 
:*Proximity of croplands.<br />
 
:*Demand of flood protection from the farmers.<br />
 
:*Proximity of the SCI ES4310027 'international Guadiana River. "
 
 
==Site description==
 
The Olivenza river is tributary to the Guadiana river. The area of actuation is not included in the Natura 2000 network but includes a riparian forest consisting of ash tree like the main species. The environmental value of the riparian forest may be considered for its funtions of corridor and buffer.
 
 
==Measures selection==
 
This should not figure here as a an ecological and hidromorphological restoration project. In fact, the project was design for flood protection, pursued by the construction of levees and weirs.<br />
 
Some of the measures can improve the structure and composition of the riparian vegetation: silvicultural treatments (clearing, pruning), elimination of invasive species and plantation of native species.<br />
 
To improve the hydraulic capacity of the river, as a way to prevent floodings, the woody debris have been removed from the channel, what can be considered an innapropiate measure, but understood if we consider the social context and the point of view of the farmers who cultivate at the floodplain. Also, 4.900 m<sup>3</sup> of sediments  were removed from the river channel.<br />
 
The engineering measures considered for flood protection include transversal hydrological correction works, with the construction of five weirs (0,6 m height) and longitudinal spots over 550 m.<br />

==Success criteria==
 
 
==Ecological response==
 
 
==Hydromorphological response==
 
 
==Monitoring before and after implementation of the project==
 
 
==Socio-economic aspects==
 
:*The project came up by initiative of the Comunidad de Regantes del embalse de Piedra Aguda (irrigation community).
 
 
==Contact person within the organization==
 
 
==Extra background information==
 
The General Department of Biodiversity of the Ministry of Environment made a report the 11<sup>th</sup> July of 2005 where one observation declaring that the implementation of the project would increase the artificiality of the flow regime, affecting, at the end, on the Guadiana river, where are located habitats of community interest(Pyro pastures bourgaeanae-Quercetum rotumdifoleae and Salicetum salvifoliolambertinae). <br />
 
The mitigation measures proposed by the General Department of Biodiversity were accepted by the project promoter, reducing the potential impact over these habitats.
