Description

<p>“Kanto-Tohoku heavy rainfall disaster on September 2015” due to an unprecedented rainfall on September 9th through 10th caused serious damage such as embankment collapse in Kinugawa River basin. Four MLIT dams in the upstream area of Kinugawa River (Ikari, Kawamata, Kawaji and Yunishigawa) contributed greatly to the flood damage reduction by implementing operations using the flood control capacity as much as possible and reducing outflow from the dams considering downstream water level and damage. The total amount stored in the dams was about 100 million m3.</p>
