In flooding, dry land capable for residential, agricultural and other economic activities is being submerged by over flow of water. This causes lost to life and property along the river basin. Effective management of these disasters by decision maker required accurate information about the vulnerable areas. Remote Sensing and GIS can be used for generation of flood vulnerability map. The method was capable of integrating the entire flood risk areas using GIS based model to provide rational and non-biased approach for making decisions in flood disaster. An attempt made to apply modern techniques like GIS and Remote Sensing for the mapping of flood prone zones risk areas. For this study, Satellite imagery was used to classify the study area into water body, open land, vegetation and built up areas while SRTM data was used for the production of slope map, drainage network, flow accumulation map, fill map and DEM of the study area from which the flood vulnerability map was produced. The contour map depicts the terrain nature of the environment has a low levelled ground and relatively flat terrain. Effective landuse planning, creation of a computerized GIS database for the flood prone areas and a detailed flood risk assessment and mapping are required to minimize the harmful effects of flood hazard.
