土石流の挙動に関する解析と磁界を用いた計測システム [in Japanese] Simulation and sensing system for behavior of mudflow [in Japanese]
Access this Article
In Japan, there are many precipitous mountains. Because of it, mudflow often occurs in rainy and typhoon season. Countermeasure for mudflow is required as soon as possible, but prediction system of mudflow has not been established yet. The purpose of this study is to establish the simulation of mudflow that is useful for countermeasure for mudflow. In flowing mudflow, boulder comes floating and it moves ahead of a flow. This phenomenon has been confirmed and published. But it has not been figured out. In this paper, this phenomenon is reproduced by the DEM simulation. And, the new measurement method for verifying the validity of a simulation is proposed. Electromotance is used for this system to be able to sense position of invisible boulder.
