Abstract

The disaster of the debris flows and flood due to the localy heavy rainfall of typhoon 16_th occurred in the area of the Shigenobu River basin, Ehime Pref. on Sept. 15th, 1999. Especially, the Omotegawa River, the left branch of the Shigenobu River, was badly damaged by the hillside failures and the debris flows. However, the Sabo facilities effectively minimized the disaster.
Here, we discussed the effects of the Sabo facilities against the disaster, using the numerical calculation.
