Abstract
It is important to known the movement of large drift, i.e. automobiles, in tsunami and its collision behavior to tsunami evacuation tower, a facility used to protect the safety of life and property in the tsunami-affected areas. For this purpose, laboratory experiments with 80 automobiles colliding with both Bridge type of tsunami tower (with a large distance between pillars) and Conventional tsunami tower (with beams between pillars) are carried out. In addition, a numerical model based on 3D Lattice Boltzmann Method (LBM) is developed for simulating the behavior of drifting automobiles due to tsunami inundation.
