In this paper, an integrated model for ocean waves propagating over a submerged coastal structure, based on COMSOL Multiphysics, is presented. In the model, Navier-Stoke Equation is solved for the wave propagation and Biot’s poro-elastic model is solved for the porous seabed. The new feature of this model is to integrate both wave and soil models into one model. This can be achieved within COMSOL Multiphysics, but will be a very challenging task with the conventional models. In this paper, we first present the model of ocean wave generation over a porous seabed, which has been limited to linear wave loading and de-coupled approaches in the past, but now we can handle the case of non-linear wave over a porous seabed. Then, we further consider two coastal engineering problems: (1) ocean waves propagating over a submerged breakwater on a porous seabed; and (2) waves over a moving structure on a porous seabed, which can be applied to wave energy converter.
