Abstract
Recently, various numerical models for wave breaking have been presented but these models can't analyze wave transformation after wave breaking. In this study, full-nonlinear numerical analysis including wave breaking and transformation after breaking has been performed in the two-dimensional numerical wave channel, installed impermeable and permeable submerged breakwater, based on the volume of fluid method(VOF
Hirt and Nichols,1981). The results of the wave profile due to the impermeable and permeable submerged breakwater agree with experimental results of Kawasaki(1997) and Kioka(1992). Very strong nonlinear waves is occurred on the crown of the impermeable submerged breakwater and wave crest is separated after breaking. Also, return flow to incident wave direction is generated after the breaking point. Vortices are formed behind submerged breakwater, and large vorticity is occurred in the breaking point.
