Flood is one of the repeatedly occurring natural disaster that brings on the detrimental impact on humans, property and environment. Frequent flood has been a major issue in almost all states of India. The importance of flood maps in governing strategies for flood risk management is of prime importance. Maps are not just for defining and communicating flood risks, but also for regulating them and for rationalizing the inevitable limits and failures of those controls. In this paper a continuous hydrological and hydraulic model has been implemented for mapping the flood caused by Baitarani River of Odisha, India. A long rainfall time series is fed into the continuous rainfall- runoff model producing discharge, which is given as an input into the 2-Dimensional hydraulic model, FLO-2D. SRTM 90 DEM data, Land use/Land cover map (LULC), soil texture data of the basin area are used to compute the topographic and hydraulic parameters. Flood inundation was simulated using the FLO-2D model and based on the flow depth, Hazard zones are specified. The result of the study shows that FLO-2D model is an utile tool for creating the inundation maps. An approach has been made for assessing the risk of flooding and proper management will help in mitigating the flood. However the current results have not been compared with literatures since much work with the model was not found. The automated procedure for mapping and the details of the study can be used for planning flood preparedness in worst affected area.
