Goutam Kumar Das, Ramu Guchait

Abstract: Soil erosion is one of the most important environmental problems, and it remains a major threat to the land use of mountainous environment. Assessment on soil erosion hazard is essential for soil conservation plans in a mountainous region for sustainable development. RS and GIS technique has been recognized as a powerful and effective tool in detecting land-use change. Its assessment and mapping of erosion prone area are very essential for soil conservation and watershed management. The RUSLE Model has been used for the average annual soil loss of the Kharkai watershed, Jharkhand, India. To achieve the goal of the thesis, the RUSLE factors were calculated.
