| Outline of Final Research Achievements |
Two layer model which has laminar debris flow near bed surface and turbulent mud flow on the laminar flow (and laminar bed load near bed surface and turbulent suspended flow on the laminar flow) is developed and derived a formula of the layer thickness of the laminar debris flow. These models are introduced the general coordinate horizontal two dimensional bed deformation model. The bed deformation model is applied to the mud flow phenomena which was occurred in Izuoshima Island and debris flow phenomena which was occurred in Yagi 3 chome, Asa Minamiku, Hiroshima.
