Lattice Boltzmann Method (LBM) is the one of the new and efficient Computational Fluid Dynamics (CFD) solvers. It has become an alternative powerful method compared with the other conventional CFD solvers. In the current study, we developed a robust tsunami simulation model by applying enhanced LBM for shallow water equations with treatments of the bed slope in the external force term in the Lattice Boltzmann equation.
The proposed model is verified by the comparison with the conventional tsunami numerical model which is based on the Finite Difference Method (FDM). As a result, LBM results are in good agreement with the FDM results. The results imply that LBM based on shallow water equations has sufficient applicability of tsunami propagation and inundation.
