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.
