Recently, locally heavy rainfall occurs frequently at highly urbanized area, and causes serious personal accidents, so importance of flood forecasting system is growing in order to reduce damage of inundation. However, flood forecasting that secured lead-time for evacuation is extremely difficult, because the rainfall flows out rapidly. In order to develop a real-time flood forecasting method for locally heavy rainfalls in urban drainage areas, we have developed flood forecasting models with two types of simplified overland surface and have evaluated these models through case studies in an actual basin. As a result, we confirmed that the simplified models had enough flood prediction accuracies in practical use. Furthermore, the computational time decreased by applying simplified models; therefore, the effectiveness of proposed simplifying flood forecasting model was indicated.
