Substantial runoff is a feature of the Ethiopian Nile River Basin because its soils are erodible and poorly organized, resulting in high soil loss sedimentation rates. The rate erosion basin was reported to be quite variable, which could owing methodology utilized data quality used. By reviewing recent studies, this review primarily aimed give information on range Recent studies at small waters...
One of the most vital problems in the storage and utilization of surface waters for drinking, flood control, hydropower, and agricultural purposes is that of sedimentation in reservoirs and subsequent decline of dam lifetime. The useful lifetime of a dam is defined as the time necessary for approximately 80% of the volume of its initial capacity to be filled by sediments washed in by water. It ...
The development of soil conservation plans and evaluation of spatially distributed erosion models require knowledge of rates of soil loss and sedimentation on different landscape elements and slope positions. Characterization of soil erosion rates and patterns within watersheds is important for the understanding of erosion processes and landscape evolution. Experimental data that show spatial t...
