%X The identification of flood vulnerability zone is very essential to minimize the damage associated with  the flood. The present study adopted the Hydrodynamic modeling technique for the identification of flood  vulnerability zones in lower Damodar river of eastern India. Preprocessing of data and preparation of various  input geometry data (river network, bank line) for the hydrodynamic model were done in an ArcGIS  environment with the help of high resolution satellite imagery and field survey. Model was calibrated for  the Manning’s coefficient of roughness (n) and validated with ground data and field photographs highresolution,  the efficiency of the model was estimated by the index of agreement ‘‘d” which clearly shows  good agreement between model data and observed data. Based on the model output flooding hotspots  were demarcated. It was observed that areas downstream to the bifurcation point of the Damodar river  are more vulnerable to flooding.
%Z The fieldwork carried out and high-resolution DEM data procurement  were funded by FRS project (FRS (120)/2017-18/ME) of  Dr. V.V. Govind Kumar, IIT(ISM), Dhanbad. Authors sincerely  acknowledge Damodar Valley Corporation Maithon, Central Water  Commission (CWC), Irrigation and Waterways Directorate, Government  of West Bengal for providing the essential data for the study  and technical support received from faculty of IIT(ISM) Dhanbad  and DHI India regarding MIKE HYDRO RIVER hydrodynamic model.
