Abstract

Soil erosion is a natural process in which earth materials are entrained and transported across a given surface mainly by wind and water. Gojeb catchment is one of the catchments found in the Omo-Gibe Basin, Ethiopia with soil erosion problems. It covers 6932.345 km². The current study was undertaken with the application of RUSLE and Geographic information system (GIS) to estimate the soil erosion of Gojeb catchment and identifications of the most affected area based on severity level. To determine the parameters of RUSLE, rainfall, soil map, Landuse Landcover, Digital elevation model data’s of Gojeb catchment was collected from different sources. The rainfall Erosivity (R), soil erodibility (K), topographic (LS), land cover (C), land management (P) were combined in Arc GIS environment using RUSLE. Annual soil loss of the catchment was determined by combining all the important parameters of RUSLE. The estimated annual soil loss value in the watershed varies from 0 to 85 ton/ha/yr, with an average value of 38 ton/ha/yr. The spatial soil erosion severity of the watershed was grouped into six classes low severity class covers 31.425%, moderate severity class covers 12.5%, high severity class covers 16.75%, very high severity class covers 7.63% sever severity class covers 11.4% and very sever severity class cover 20.3% of the area depending on soil loss hazards. In Gojeb catchment concerning stakeholders, for the different districts, which have exposed to very high to extreme sever loss classes given immediate priorities to proper conservation and mitigating measures.
