A numerical model is developed to simulate landslide-generated tsunamis. This numerical model is based on the Large Eddy Simulation (LES) approach, solving three-dimensional filtered Navier-Stokes equations. While the Smagorinsky subgrid scale (SGS) model is employed for turbulence closure, the Volume of Fluid (VOF) method is used to track the free surface and shoreline movements. A numerical algorithm describing the movements of a solid landslide is also developed. The numerical results are compared with laboratory experimental data (The benchmark problem 4). A very good agreement is shown for the time histories of runup and generated waves. Based on the numerical results, the detailed 3D complex flow patterns, free surface and shoreline deformations are further analyzed.
