The 2011 T_hoku earthquake showed that even the most sophisticated defenses like the massive Kamaishi bay breakwater were insufficient to prevent catastrophic flooding of the coast line. This paper will deal with the Fluid-Structure Interaction (FSI) simulation of a breaking tsunami induced flooding wave upon a coastal infrastructure. It will examine methodically the problem from simulating the tsunami induced wave slamming and flooding of a building, to the impact upon a typical Liquid Natural Gas container and finally the large scale simulation of the event on a coastal installation like a nuclear power plant. It will be shown that the basic technological capabilities needed for the realistic simulation of the tsunami induced flooding events are available in the Virtual Performance Solution (VPS) suite of codes from ESI Group and that assessment of coastal protection against flooding due to tsunamis has become feasible.
