Description
The Hamada River Basin located in the west part of San'in District, suffered severe disasters from flood caused by record heavy rainfall in July 15, 1988.
The maximum amount of rainfall in Hamada Dam Control Center was recoded as 107.Omm in 1 hour, 458 mm in 24 hours. And peak discharge of inflow into Hamada Dam was observed as 585.88 m^3/s, which exceeded the value of design flood discharge, 430.0 m^3/s.
In order to clarify the flood characteristics in Hamada Dam Basin, we carried out the flood runoff analysis apllying the KWST Model which is developed as a runoff model combined kinematic wave and storage tanks.
We showed that the simulated inflow hydrogragh into Hamada Dam explained well the period of flood peak runoff. Furthermore, we estimated the flood concentration time as 116~120 minutes, and peak runoff coefficient as 0.74.
