==Key features of the case study==
Arroyo del Partido collects water from a watershed of 308 km<sup>2</sup> caracterized by a torrential behavior. Land use changes (and agricultural practices)and channelizations have induce problems of erosion, transport and deposition of sand.

==Monitoring before and after implementation of the project==


The Doñana 2005 programme includes several studies to know the ecosystems´condition before, during and after the actions.Among the studies figure:<br />
:* Hydrogeomorphology<br />
:* Physical and chemical quality of water and fitozooplankton<br />
:* Aquatic and terrestial vegetal communities<br />
:* Estuary and freshwater macroinvertebrates<br />
:* Vertebrate communities<br />

These studies started with the first project of the programme and lasted few years after the last one was finished.

==Extra background information==
Arroyo del Partido has been channelized its final reach for flood prevention. Removing the wall of the left margin, the expansion will allow the water to recover the original floodplain and restore the alluvial fan at its confluence with the marsh. 
The wall of the right margin is maintained and reinforced to protect the strawberry fields and other irrigation farmland. 
This action includes forestry and agri-environment measures, including restoration of the stream margins and actions in the alluvial fan to restore the natural appearance.<br /><br />
