Assessment of Soil Erosion Using USLE Technique: A Case Study of Mysore District, Karnataka, India

Abstract

The present study has been conducted to assess the soil erosion in Mysore district in Karnataka, India. The most widely used Universal Soil Loss Equation (USLE) method has been adopted for the analysis. The USLE method performs based on the five parameters such as, rainfall factor, soil factor, length and slope factor and conservation practice factor. Each necessary numerical data have been obtained from the concerned organization and satellite images have been downloaded from appropriate websites. The spatial data have been manipulated and analyzed using GIS while the numerical data have been analyzed using MS-Excel. The result of study represents that, most of the area is covered by very light erosion followed by very severe erosion.
