Sensitivity of turbulence models and grid resolution are investigated in the simulation of collapse of a water column by a three-dimensional tsunami analysis with VOF method in comparison with the previous experimental results. LES turbulence model is found as an effective model in simulation of tsunami wave run-up on shores. High mesh resolution or mesh refinement need to be adapted around walls to simulate the collision of tsunami wave on buildings and structures. The performance of the tsunami analysis is also confirmed in comparison with a tsunami run-up water tank test. A large-scale simulation is carried including a wide urban area with complex terrain. Local concentration of high wave height distribution in narrow steep terrain and inhibitory effect of buildings and structures on tsunami run-up have been found.
