Recently, an interior water inundation disaster is increasing in an urban flood type. It is known that there is a limit in hard facilities. Therefore, it is needed that is publishing of a hazard map, various interior water inundation analysis models are proposed, and also reported as soft measures. However, there are few examples of the report supposing the inundation zone of high accuracy. This study demonstrated inundation mechanism of a detailed river and sewerage of urban area by anumerical model. A using model in study is called as NILIM. This NILIM model connected with the flood analysis which used two-dimensional unfixed style model of ground surface flow and hydraulics analysis such as sewerage. In the simulation of a typhoon No. I I in 1993, inundation zone of approximately 60% toward total flood area has appeared again by using NILIM. In the simulation of a typhoon No.18 in 1982, an interior water inundation was happened at the every place because of it was the flood control plan in a exceed precipitation.
