Recently, in Tokyo, a local torrential rain more than 100mm for one hour has been happened by heat island effect. In this study, reduction effect of peak flow with increased storage capacity on the annular No.7 line underground reservoir was analyzed by simulation based on data. As regards to characteristics of rainfall distribution, it was quantitatively evaluated using runoff rate and reduction rate. As a result, difference of reduction rate was clarified by rainfall characteristics. Therefore, those influences, which characteristics of rainfall gave to reduction effect of peak flow was examined by rainfall analysis by Gumbel method. As a result, the case that heavy rain persistently from two hours for four hours has low reduction rate was led.
