Abstract
AbstractIn this investigation, an effort was made to model the hydrology and to identify critical erosion-prone areas of the Barakar Basin (6,293 km2) in Jharkhand state, India using the soil and water assessment tool (SWAT). This effort is helpful to select and adopt suitable soil conservation measures to reduce soil erosion. Input data include daily rainfall, and air temperature; and monthly runoff, sediment yield and reservoir inflow data of 5 years. Additional data were the topographical map, soil map, land resource data, and satellite imageries of the study area. The model was calibrated and validated for monthly inflow to the Maithon and Tilaiya Reservoirs for the periods of 1997–1999 and 2000–2001, respectively. In addition, it was also calibrated and validated for monthly runoff and sediment yield from two subwatersheds (Banha and Karso), located within Barakar Basin for the monsoon season of the same period. The calibration and validation results established good agreement (less than 10% deviat...
