Simulation of Propagation and Run-Up of Three Dimensional Landslide-Induced Waves Using a Meshless Method

Abstract

Abstract:In this study, a meshless numerical model for the simulation of tsunamis generated by submerged landslides was developed. The phenomena were treated as free surface potential flows governed by the Laplace equation. By using a predictor-corrector time marching approach, the time dependent problem was transformed to a series of boundary value problems (BVP) while at each time step the BVP was solved by a meshless method which employed local polynomial collocation accompanying the weight-least-squares (WLS) approach. The model was validated by comparing the results with experimental data and other numerical results. Then, simulations were carried out in a widened numerical wave flume for the observation of edge waves along the shore.

Hsiao et al [3] developed a meshless numerical model for simulating tsunamis generated by submerged landslides. Karahan et al [4] evaluated the potential landslide area of impulse waves using 3D numerical simulation-based models for the Tersun Dam reservoir.…”
