A accurate numerical simulation of flood and the resulting inundation map is useful for the planning of hazard prevention. An hour-by-hour report and prompt prediction of actual flood is also important to reduce the damages, although numerical model for prompt prediction of flood is not investigated sufficiently. In this paper, accurate and low-cost numerical model is developed. This model adopts the topography-fitted grid system; hence number of grid decreases to 1/7 in comparison to the rectangular grid system. The present model makes the prompt prediction of flood possible. In addition, the application system is developed by combing the geographical information system and the present numerical model for flood inundation. This system has the functions of viewer of numerical results, calculation of flooded area and number of damaged houses and finding the route of refuge.
