Remote sensing data and GIS techniques have been used to compute average annual soil erosion for the SA-13 watershed having area of 21,300 ha. Watershed SA - 13 of Ashti, Beed District of Maharashtra state (750 04' 55" to 750 16' 25" E longitude and 180 40' 11" to 180 56' 20" N latitude. Multidate satellite data of IRS P-6 LISS III of path 059 and row 096 with 23.5 m resolution was used. Different types of thematic maps viz., Administrative Boundary maps, Slope map, Land Use Land Cover map and rainfall maps were developed to estimate the different parameters required for the calculation of the soil erosion. Annual soil erosion was estimated using the Revised Universal Soil Loss Equation model. The watershed was divided into 15 sub-watersheds. The highest soil erosion of 9.97 t/ha/year was observed in micro-watershed number 4, whereas lowest soil erosion of 5.59 t/ha/year was observed in micro-watershed number 13. The average annual soil erosion from SA-13 watershed was found 8.2 tons/ha/year.
