Key features of the case study

Arroyo del Partido collects water from a watershed of 308 km² 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

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.
