Abstract
In this study, we attempted to simulate the phenomenon that the debris flow is flowing down from the dangerous mountain on the 2 dimensional mesh space by using the multi-agent system. This is possible to set up some elements in the debris flow with more practicable method by using the multi-agent system than the numerical simulation. And so, it is possible to control the movement of each element in the debris flow by some simple local rules. It is easy to understand and modify the parameters in the local rules.
