Abstract
A virtual flood scenario has been constructed to investigate the overflowing process in the flooding area. The topography is constructed using the airborne LIDAR data. In addition, the frequency and scale of the flooding and the destruction condition of the flooding defensive structure are used as input to the scenarios. Through the scenario, the inundation depth with respect to time and maximum depth has been analyzed. This analysis shows the water level variation with time which show the flooding process. Moreover, a flooding map is drawn using the results from the scenario, distribution of the defensive structure, vulnerable area, and expected destruction points in the study area. It is expected that this study can be effectively used to examine the flooding process and flood disaster management. Furthermore, it could provide important basic information for the land development and the city planning of a possible flooding area.
