A Study on Estimation and Comparison of Average Annual Soil Erosion With Different Slope Length [l] and Steepness Factors[s] by Rusle Model Using Remote Sensing and Gis Technology
Year: 2015
Type: article
Abstract: In this study the author has been made an attempt using RUSLE equation in two different cases by considering L and S factors used in the equation. The present study demonstrated the discrimination of soil erosion losses with different slope length and steepness factors by the application of RUSLE equation to assess Average Annual Erosion of the Gumani watershed. The utility of high resolution DEM data to derive topography factors of Slope length (L) and Slope steepness factors (S). Preparation of land use land cover map is an important component while computing the land cover management factor and erosion control practice factor for soil loss estimation. The results showed that the Gumani watershed has an average annual soil loss grid value upto 40 t/ha/yr of case 1 and a huge variation of Soil erosion in case 2 as the maximum grid value obtaind 1160 t/ha/y. In both the cases the maximum area contributing to soil erosion from urban and fallow lands. However the steepness of slope factor(S) is higher in case of separate ‘S’ factor calculation leads to higher occurrence of erosion losses take place.
