To estimate the effects of small scale rain storage facilities for flood control, the model which can express inundation proccess in detail in urban area is built in this paper. The probable rainfalls are used systematically to make their effects clear. It is shown that they can control the flood significantly for rainfalls whose return period is less than 50 years. On the other hand, it is required to reinforce the drainage capacity to cope with the very heavy rainfall whose return period is more than 50 years.
