Abstract

<p> In recent years, the weather has become more extreme on a global scale, and as a result, heavy rainfall has occurred frequently in various places. Even in large cities with advanced sewerage networks, unprecedented heavy rainfall can cause flooding of rivers and flooding of inland waters. In this study, we performed a reproduction calculation using the actual rainfall data of Typhoon No. 19 in 2019 observed by XRAIN of the MLIT in Chofu City, which is the basin of the Tama River.In this study, we performed a reproduction calculation using the actual rainfall data of Typhoon No. 19 in 2019 observed by XRAIN of the MLIT in Chofu City, which is the basin of the Tama River. At the same time, we also examined how the handling of gutter pipes and gutter gates in the target area would affect the rainfall conditions at that time. In addition to this, we also deal with damage that occurred in Ota Ward and Setagaya Ward. This reproduction calculation applies the results of past calculations in the 23 wards of Tokyo, Kawasaki City, and Yokohama City to Chofu City.</p>
