N2 - This study describes a numerical simulation method for dyke breach process due to overflow based on Moving Particle Semi-implicit (MPS) method. The MPS method was developed for incompressible flow with free surface. In the MPS, fluids and geomaterials to be analyzed are represented by particles, and the governing equations describing the mechanical behavior are discretized by particle interaction models. Since MPS method does not need grids, it can be applied to large deformation behavior such as dyke breach process. The MPS method was extended by adding a simple erosion model for simulating breach process of dyke due to overflow. The simulation results for breach process of the dyke by the MPS method were compared with the corresponding observation data to verify the applicability of the MPS method presented in this study.
