Effectiveness and geomorphological impacts of check dams for soil erosion control in a semiarid Mediterranean catchment : El Cárcavo (Murcia, Spain)

Abstract

The effectiveness of transverse structures (check dams) and their effects on the morphology of ephemeral channels (ramblas) were investigated in a semiarid, highly degraded catchment. In the study area, 36 dams were surveyed, of which 29 were filled up with sediments, 2 had been destroyed and only 5 had still not completely filled with sediments. Field observations of changes in the cross-sectional shape of the stream channel, the composition of channel bed material, and bankfull stage measurements indicated that the dams cause erosion downstream
