Abstract: An accurate understanding of the hydrological behavior of a watershed is important for effective management. Runoff is the most basic and important data needed when planning water control strategies/ practices, such as, waterways, storage facilities or erosion control structures. The most popular method used for runoff estimation is SCS runoff curve number method. In the present study Darewadi watershed was taken as case study for highlighting the role of GIS and RS in estimation of runoff from the watershed by SCS curve number method using OVERLAY techniques. 20 years daily rainfall data was acquired from Indian Metrological Department (IMD), Pune. The study reveals that the SCS-CN model can be used to estimate surface runoff depth when adequate hydrological information is not available.
