Abstract

The evaluation of wave-induced pore pressures and effective stresses in a porous seabed near breakwater heads is important for coastal engineers involved in the design of coastal structures. Most previous studies have been limited to two-dimensional (2D) or three-dimensional (3D) cases in front of a breakwater. In this paper, a three-dimensional numerical model for the wave-induced seabed response around breakwater heads is developed. The 3-D wave model was based on the Navier-Stoke equation with wave generation model. The seabed is simulated by the Biot’s poro-elastic dynamic model. Both models are linked together to form the PORO-WSSI (3D) model. Based on the newly model, the soil permeability and the degree of saturation significantly affect the wave-induced oscillatory pore pressures.
