Abstract

This study investigates numerically 3-D flow characteristics and wave height distribution around permeable submerged breakwaters. At first, the 3-D numerical model, which is able to consider the flow through a porous medium with inertial, laminar and turbulent resistance terms and determine the eddy viscosity with the sub-grid scale turbulence model, is newly proposed. The numerical model is validated in 3-D wave field by comparing with existing experimental data for wave transformation around permeable submerged breakwaters. And then, using the numerical results the 3-D flow characteristics around submerged breakwaters are examined in relation to wave period and crown depth. Moreover, the wave height distribution and wave set-up around them are also discussed as well the distribution of wave breaking points over the crest.
