The effectiveness of check dams in stream morphology and sediment deposition (A case study: abjovan watershed, Fars province)

The effectiveness of check dams on the morphology of ephemeral channels and their impact on sediment deposition was investigated in a semiarid catchment. According to results, dams located in downstream were more effective in deposition of fine sediment than upstream dams. The results showed that dams influenced the width/depth ratios. The stream channel became wider and flatter in downstream, resulting in an increase of the volume of sediment and present of fine sediments from upstream to downstream.
