Slope slides, dry rock avalanches and debris flows frequently take place in mountainous areas following strong earthquakes. Various types of flow analysis have been made based on a continuous medium. But, as the rocks and soil which are contained in rock avalanches and debris flows, are discontinuous not continuous materials. We have developed a modification of Distinct Element Method in which the effect of water present between particles is taken into account. By using the extended DEM for debris flows, we could follow their flow processes and compare them with those of the dry rock avalanches. In addition, we obtained simulation results that explain the flow behaviors when the flow makes an impact with dam wall and the deposition process. キーワード（英）： - 記事区分： - 区分 　　　　論文集
