| Abstract | Bangladesh is considered to be a country worstly affected by recurring floods with devastating dimensions exposing the national economy in the hands of nature. Complete flood control in the geographical context, particularly in the deltaic form of Bangladesh is not at all a feasible option. Structural methods of flood protection are neither economically viable nor these are environment friendly. Therefore, non-structural methods are becoming popular in mitigating flood disaster. A good way to prevent/ reduce damages occurred from flood is to develop a Flood Forecasting and Warning System in the affected area. This study aims to fulfill such requirement by the extensive use of GIS, providing spatial information for assessment of flood vulnerability. A methodology has been developed by integrating Hydrodynamic Model MIKE 11 and GIS. The MIKE 11 flood forecasting system comprising of three modules of NAM, HD and FF is used for flood foresting. A Geographic Information System (GIS) is a powerful tool for describing, analyzing, modeling and integrating spatial data with other related inf01mation such as topographic, thematic and attribute information. It offers new opportunities to develop and implement a user-friendly, interactive decision support system for flood forecasting and identifying the affected areas using dynamic spatial modeling to find out safer location for evacuation. The study concludes that an effective Warning System can release warning in advance, say 72hrs, 48hrs and 24hrs. It can change the existing scenario substantially and render informed decision making in adopting proper measures towards disaster preparedness, mitigation, control, planning and management. |
