A vast amount of numerical and experimental results are presented in this final report. Numerical simulations are performed by the TUMMAC-Vot program to know the effect of Froude number on the breaking bow waves, as well as the effect of shear flow near the free-surface. The existence of a critical Froude number for the occurrence of large-scale breakers and the variation of the breaking behavior, from spilling to plunging type, due to the increase of Froude number are demonstrated. The shear flow is proved to be influential to wave-making, breaking and vortex generation. Experimental analyses are made using grid-projection method, flow visualization and turbulence measurement techniques. The experimental results partly verify the usefulness of the numerical simulation and partly indicate further complexity of the wave dynamics with turbulence.
