Outline of Final Research Achievements

Dense pyroclastic flows were modeled under the shallow layer approximation, where a granular friction model with a dimensionless number related to physical parameters of the flow (friction angles, grain-size, flow velocity and thickness) was employed. When the model was applied to actual examples of pyroclastic flows, the model could successfully reproduce the major characteristics of the deposits such as distribution and shape. This study showed the importance of introducing the granular friction law into numerical models when we analyze formation processes of pyroclastic flow deposits, and assess pyroclastic flow behaviors and resultant hazards.
