Water is one of the necessary normal resources, without which life cannot survive. Insist of water is rising with the raise of population. We require water for farming, manufacturing, and person and livestock utilization. Therefore it is very significant to direct this very important resource with sustainable approach. Hence, we should correct supervision and growth development to return or refresh water where overflow is very far above the ground owed to a variety of topographical situation. The Runoff evaluation technique is one of the major RS & GIS tool for prioritization of watershed. Soil Conservation Service Runoff Curve Number is a quantitative descriptor of the land use/land cover, soil composite personality of breaking point and its compute straight runoff during an practical relation that requires the rainwater and watershed co-efficient namely runoff curve number. The SCS Curve Number approach to runoff quantity is naturally consideration of as a technique for generate runoff for unusual actions and not for water feature plan. The parameters were obtained with the help of Erdas Imagine, Arc GIS and MS Office. The methodology modified from SCS method for the continuing runoff opinion for each watershed is how much prioritized. The mean of the minimum flow data collected at the measurement station has been considered as baseflow of the stream in that watershed, which is an important component of total flow. The total flow of these watershed where measurement of flow data has been undertaken been identified by adding the base flow data and the runoff calculated by CN method.
