We have been developing an inundation prediction system in colabolation with Ube city for these several years. This system predicts the inundation areas due to a flood of a river by a rainfall in real-time. Last year, we introduced this system the influence of the tide level that will strongly affect the possibility of the inundation. Ube city was attacked by the typhoon 9918 (T9918) last year and serious inundation damage occurred around the mouth of A river. Therefore, we started the observation of the change of the water level of A river due to rainfalls. In this study we tried to evaluate the most important factor, such as the rain fall, the tide level and the deviation of the tide level due to strong wind, that caused the inundation by using the inundation prediction system. The simulation results implied that the deviation played a very important role to cause the serious inundation.
