Water Balance Assessment Using Q-SWAT

The factors influencing decrease in water level are related to one another, such as scanty rainfall, excess evaporation, land use changes, deforestation and smaller amount of groundwater recharge which fallout into inadequate supplies in most parts of Maharashtra. To meet the demands of the area; proper planning for judicious use of limited resources is essential. The study has been carried out to determine the availability of resources in small watershed which lies in Gangapur District, Maharashtra. The analysis has been carried out by using QSWAT 1.2 for time period of 33 years from 1979 to 2012. Daily data of precipitation, temperature, radiation, wind velocity and solar radiation has been processed on monthly time scale. After proper watershed delineation; the graphical and numerical summary of the simulated results for hydrological parameters such as Actual Evapotranspiration, Groundwater Contribution, Potential Evapotranspiration and Surface runoff are represented.
