Abstract
This paper presents a numerical model based on the hydrodynamic shallow water equation, which is developed for simulations of landslide-generated waves in reservoirs and bays. The Galerkin finite element method is used to determine the amplitude of the waves, which is generated by accelerating the fluid due to bottom physical displacement, the bottom friction, and impact force due to landslide. The model is verified by the good agreement between the simulation and the theoretical analysis. In order to consider the case of complex topography and practical boundaries, auto-generation method of the modified Delaunay triangulation element is applied to the numerical model. In addition, the case of a landslide into reservoir is simulated and discussed. It shows the possibility to numerically analyze the waves caused by landslide into a reservoir with complicated topography.
