Numerical Simulation of Landslide Impulsive Waves by WC-MPS Method

Numerical simulation has been widely used for solving engineering-related problems in the past few decades. Because of the flexibility, efficiency, and compatibility of numerical simulation, it has been involved in various engineering and science areas. This approach is capable of interpreting the natural phenomena, and also offering an alternative way of theoretical studies and experiments. In this study, the weakly compressible moving particle semi-implicit (WC-MPS) method is applied to simulate the impulse waves generated by landslide. During this study, the complete theory of the WC-MPS model was applied/adopted. The model was modified to simulate the impulse wave for the different landslide cases. This study includes the simulations for the submerged and un-submerged landslide cases, the introduction of deformable and solid sliding blocks, and also the first-hand comparison between WC-MPS simulation and experiments. After comparing WC-MPS simulation with experimental results for different cases, the applicability of WC-MPS method in simulating the impulse wave generated from landslide is confirmed at the end of this study.
