Abstract

Rainfall runoff is an important component contributing significantly to the hydrological cycle, design of hydrological structures and morphology of the drainage system. Estimation of the same is required in order to determine and forecast its effects. Estimation of Direct rainfallrunoff is always efficient but is not possible for most of the location at desired time. Use of remote sensing and GIS technology can be used to overcome the problem of conventional method for estimating runoff caused due to rainfall. In this paper, modified Soil conservation System (SCS) CN model is used for rainfallrunoff estimation that considers parameter like slope, vegetation cover, area of watershed.
