This is the final report of the study titled “Use existing data on available digital elevation models to prepare useable tsunami and storm surge inundation risk maps for the entire coastal region”.  This report contains the inundation risk maps of tsunami and storm surge for the coastal region of Bangladesh. The risk maps have been developed based on the simulation results of tsunamis and storm surges and the updated Digital Elevation Model. This report has been finalized after incorporating the comments received from the International Workshop on “Tsunami Hazard Assessment and Management in Bangladesh” held on 21-22 January 2009 and the TAG meeting held on 28 March 2009.
