Some part of Flood Protection Law were revised for the purpose of reducing floods in May 2005. And responsibilities for publishing the flood susceptible area were extended to the small river in an urban area. Then it is necessary to predict the flood susceptible area in the region existing small rivers. However, it is difficult to predict the area existing several rivers because they influence each other. In this study, in order to grasp the mutual influences of rivers on floods, we compared two flood analyses, one is to consider the two rivers separately, and the other is simultaneously. Aiming at the temporal change of inundation depth, there is a difference between the former analysis and the latter analysis. On the other hand, inundation area in the latter analysis is estimated by using the former analysis's result.
