Abstract:
The relationship between land attributes and soil erosion process becomes major consideration as resource conservation and development related programmes are being taken up on watershed basis. This study facilitates to obtain such land attributes like soil erodability (K), slope length and steepness (LS), cover management (C) and conservation practice (P) which acts as important input factor to estimate soil loss in selected watershed using MUSLE. The area covers 101.34 km² between 16º 15’- 16º 30’ latitudes and 77º 15’- 77º 30’ longitudes. The basic required thematic maps were obtained using Geographical information system tool with processed satellite imagery. The final results of the study gives all the five input factors map (K,LS,C,P) including soil loss map for the watershed. The result revealed that 77.49 t ha^-1yr^-1 soil losses occur from Timmapur watershed when calculated using Kirpich time of concentration.
