Recently, we often experience a localized torrential rain whose intensity is much larger than the design intensity for drainage network systerm. In such a case, severe damage of inundation is expected especially in urban area. In order to reduce the magnitude of damage, the information obtained by numerical simulation is so effective. Recently, the authors have started the attempt for a real-time forecast of inundation as well as the localized torrential rain. In this paper, two numerical prediction techniques in each field were summarized. Numerical simulation of inundation was newly attempted by using the observed mesh-data of rain, and the discussion about the results of prediction was also conducted.
