Numerical study of submarine landslide generated tsunami using smoothed particle hydrodynamics method

Abstract

Submarine slide is the most serious threat on both local and regional scales. Tsunami phenomenon induced by submarine slide has put us on the challenge in understanding from generation mechanism to propagation and coastal inundation and mitigating the risk from submarine slide generated tsunami. This research presents the numerical simulation methodology by using Smooth Particle Hydrodynamics (SPH) to investigate all stages of tsunami waves with the aid of physical modeling. Results of tsunami generation, propagation, run-up, impact in experimental test are compared with the results from the numerical simulation. The comparisons of results have a slight difference. The conclusions may potentially be taken as guideline of mitigate the risk from tsunami wave.
