Applicability of Numerical Simulations for Ductility Design of Breakwaters against Mega Tsunami

The design to strengthen coastal defence structures with their ductility is going to be employed. This study applies three different numerical models; CADMAS-SURF2D-OpenFOAM and MPS, to verify their accuracy compared with the hydraulic experiments of breakwaters under tsunami load and to clarify their applicability for ductility design. In case that tsunamis overflow crown heights of breakwaters extremely, it was suggested that tsunami velocity behind breakwaters could not be simulated accurately by CADMAS-SURF2D, while OpenFOAM and MPS had good agreement with experimental results. It was also found that numerical results may lead to underestimate necessary weights of armor blocks.
