Utilizing Geographic Information System for Prediction of Soil Erosion in Sono Sragen Catchment Area
Problem statement: Embung is a small dam created by manmade lakes and used to catch water during rainy season for an irrigation source. In Sragen area, Embung Sono is one of around twenty embung that used to catch rain water for irrigation. Soil erosions in catchment area are potential to reduce water capacity of the embung. Although many embung have been constructed in Sragen areas, the numbers of soil erosion in catchment area of embung are not well considered. Approach: Soil erosion in the Sono catchment area was analyzed using Geographic Information System (GIS) and Universal Soil Loss Equation (USLE) method. Results: The result showed that total number of soil erosion in the Sono catchment area is 63.50 ton/ha-year and categorized in moderate classified. Value of Sediment Delivery Ratio (SDR) for catchment was 0.34. Empirical equation proposed by Renfro, Vanoni and USDA were also used to analyze the SDR value. Conclusion: It was found that USDA is the best method that can be used to predict soil erosion in Sragen area. It means the crop management and environmental conservation in Sono catchment need to be improved.
