Abstract

This study discusses the results of laboratory analysis to evaluate the effect of rainfall intensity, slope steepness, soil types and antecedent moisture content on sediment concentration, runoff coefficients, and sediment enrichment ratios. To achieve the objectives, laboratory experiments were conducted using FEL-3 rainfall simulator and erosion pan on 3 soil types found in Alemaya watershed, eastern Ethiopia Alemaya Black soil (Soil A), Regosols (Soil B), and Cambisols (Soil C). Results of the study indicated that the actual effect of slope as well as rainfall intensity on sediment concentration and sediment yield vary with soil types and moisture contents
