Description :
In this study, reservoir sedimentation and corresponding catchment attribute data were used to investigate the major factors controlling sediment yield variability in a mountainous dryland region of northern Ethiopia. Sediment yield data were acquired for representative 11 catchments above reservoirs. The results show that terrain form, gully erosion, surface hydrology, and land cover explain most of the variability in sediment yield among the catchments.
