Because debris flow which can become a trigger of landslide-induced tsunami is solid-liquid multiphase flow, its configuration varies with concentration and density of solid phase. As a model of debris flow, a rigid body, higher density fluid and non-Newtonian fluid have been treated in previous simulations. While in the previous studies by the MPS method, a non-Newtonian fluid model have applied to only single phase flow analysis. Therefore, in this study, a non-Newtonian fluid model coupled with Newtonian fluid model is developed. This model is applied to landslide-induced tsunami simulation and its validity is examined.
