Abstract: Increased human activity, growing demands and limitations in water supply have made it absolutely necessary to pay greater and closer attention to the management of water resources. Water engineers and scientists are confronted with challenges of sustainable development and have the responsibility to meet these challenges, both at the macro-level of overall demand and supply and at the micro-level, by designing, operating and maintaining water resources with the objective of local sustainability. The present study aims to study the water balance of a watershed located in Khuldabad, Aurangabad, and Maharashtra, India. Digital Elevation Model (DEM), boundary map, land use map, soil map and weather data of the study area are the inputs to QSWAT. QGIS 2. 6. 1 Brighton was used to developed DEM and thematic maps, such as soil map, Land use Land Cover map of study area. The analysis has been carried out by using QSWAT1. 2 for time period of 33 year from 1979 to 2012. Daily data of precipitation, temperature, radiation, wind velocity and solar has been processed on monthly basis. The delineated watershed is divided into 14 sub basins. SWAT output gives the simulated result for hydrological parameter in graphical and numerical format. The SWAT output can be effectively visualized by SWAT Check 1. 2. Hydrological components of sub basins are obtained on monthly basis using SWAT Check. The output of one sub basin is presented graphically and statistically. The total area under the 14 sub basins is 19. 90 km2. The average monthly basin values of rainfall, surface runoff, water yield, sediment yield, evapotranspiration and potential evapotranspiration are obtained for the basin using SWAT Check
