摘要

Identification of runoff generation areas and erosion prone zones of a watershed are important for the efficient and effective implementation of the greatest management practices for preserving the natural resources. In the present study, an effort is completed to recognize the critical erosion-prone zones of the study area by using the spatially distributed parameters liable for hazards of erosion. Remote sensing and GIS techniques were used for generating parameters with soil erodibility factor, slope factor of stream power index, Universal Soil Loss Equation, topographic wetness index for water conservation, curve number value and sediment transport index. By using supervised classification technique with a maximum likelihood technique was applied to three multi spectral bands to create the land use/land cover map and classified into six land use land cover classes. The soil-erodibility factor map was made by using soil map and K-factor values and thus divided from low priority to high.
