The grain stresses arising from interparticle interactions in a solid-liquid shear flow at high concentration and high shear rate are theoretically evaluated, based on the microscopic observations of interaction mechanism among grains. By using these results, the characteristics of debris flow such as velocity, depth and concentration are analyzed. Three series of experiments were carried out in a flume 15 cm wide, 30 cm deep and 7 m long with a transparent acrylite wall on one side.
