Minamata City had heavy rains on July 20, 2003. As a result, a large-scale of landslide occurred on right-hand side slope of a mountain river in Minamata City. The landslide changed into debris flow and moved down the mountain river. In the downstream reach at mild slopes, the debris flow caused sediment deposition and moved over river bank. In order to measure such disaster we have to know the detail of the debris flow behavior. The purpose of the present study is to propose a debris flow simulation model for the mountain river and investigate the process of the debris flow disaster. We can see that the damage to the houses on the right-hand side of the river reach was serious because of the larger drag force.
