Abstract

Direct numerical simulation capability using a level set method is developed for the study of water surface wave interacting with bottom mud flow. Simulation of plunging breaker is performed to investigate the effect of muddy seabed on wave breaking. It is found that in the presence of mud, the intensity of wave breaking is reduced, the dissipation in water decreases, and the dissipation in mud plays an important role in wave energy evolution. Before the impingement of plunging jet on wave surface and after 2.5 wave periods when most of the wave energy is lost, dissipation in mud dominates that in water. During the wave breaking, dissipation in water increases sharply and exceeds that in mud.
