| dc.description.abstract | Soil erosion is the deterioration of soil by straight forward of the physical movement of soil elements from a given site and the main catchment problems in the high land of Ethiopia. This research mainly aims to evaluate Land use and land cover change on soil erosion using RUSLE model and to investigate land-use/land-cover changes of 20 years using satellite image of Landsat 5 TM 2000, Landsat 7 ETM+ 2015 and Landsat 8 OIL2020. RUSLE model is used on the basis of the improved procedure parameter for. To achieve Ethiopian highland conditions and the rate of annual soil loss various spatial data were collected and used this objective, Digital Elevation Model (Mdemu et al.), Google earth map, Rainfall data and Digital soil map from FAO were used. The created factors were joined organized and used to compute the potential annual soil loss in the study area. The result of this study shows that the total amount of soil loss was ranges from 0.00 to22965.3 tons/ha/yr. Besides, the average soil loss for this catchment was calculated to be 208.5ton/ha/year from an area of 43,119.45 hectares of land. Accordingly the level of soil erosion rates, the catchment divided into seven priority categories for soil conservation. An areas which are also classified, as severe to extremely sever the erosion classes which covered an area of 500.65 ha, (1.1%) of the total catchment, while high to very high erosion classes reports an area of 1971.2 ha (4.6%) and 1230.9(2.9) respectively, and which founds northeastern, south eastern, south and some central parts of the Jemma catchment. On the other hand, low erosion classes covered an area of 34359.8ha (79.7%), and moderate erosion risk class covered an area of 5057.9 (11.7%) and which founds most of the central and north western parts. To prioritize the catchment was identified based on their average annual soil loss for future intervention and soil and water conservation measures:- AS the study recommended that the rate of erosion which greater than (>45tons/ha/yr) should be given first priority during the introduction of intensive and well-designed integrated management interventions for soil conservation. | en_US |
