Floods emerge due to various reasons depending on the climate, vegetation cover and geology prevailing in that area. The threats to floods are prejudiced by the rate and alacrity of rural land runoff within the watershed. Proper flood management system must be executed to tone down the flood induced hazards. This paper focuses on simulation of hydrograph by integrating Remote Sensing (RS), Geographic Information System (GIS) and hydrological models. SCS curve number method is employed to determine the right curve number of the Dasarikuppam sub watershed, a rural watershed in Chennai which defines the runoff potential. A simplified procedure is adopted to generate flood inundation hydrograph using Shuttle Radar Topography Mission (SRTM) Digital Elevation Model (DEM), hydrologic soil group number, land use and rainfall data. Results suggest that combination of RS, GIS and hydrological model is reasonable, reliable and flexible when compared with traditional solutions.
