<p>This paper presents an analytical approaches on segregation phenomena and its occurrence condition of woody debris using DEM. In advance, a ball mill experimental device is used to observe behavior of water, dry woody debris, and woody debris. The water in the experiment make similar shape of surge observed in debris flow in situ. The woody debris cause several type of moving phenomena including segregation of woody debris. DEM is used to simulate those results. The method suggests a new model to experess water behavior. The element has a special shape like a sphere, and a constitutive law for water pressure translation mechanism and momentum following DEM. The simulation reproduces the experimetnatal results and makes clear the segregation mechanism.</p>
