Abstract

This paper presents a 2D fully nonlinear numerical investigation on tsunami wave impacts on onshore structures by the meshless local Petrov-Galerkin method based on Rankine source solution (MLPG-R) and a hybrid approach QALE-FEM/StarCD, which combines the Quasi Arbitrary Lagrangian-Eulerian finite element method (QALE-FEM) based on the fully nonlinear potential theory and StarCD. Both methods are at a similar accuracy level for modeling violent wave impacts but the former has higher computational efficiency. After a preliminary study where collapsing water column is used to approximate the overtopping portion of tsunami waves, investigations considering both the wave propagation and the violent impact on structure are carried out. The effects of a water pool in reducing the tsunami wave impacts are discussed.
