In this paper, the Coulomb-damping friction is considered in the problem of the wave-seabed interaction in a porous seabed of finite thickness. A closed-form analytical solution will be presented here. In the model, we couple the water waves and porous seabed with a complex wave number. Thus, the effects of soil properties on the wave characteristics can be examined. The numerical results indicate that the coulomb-damping friction significantly affects the wave-induced pore pressure in a finer seabed (such as fine sand and clay). Also, the wave characteristics have been significantly affected by the wave-induced seabed response.In this paper, the Coulomb-damping friction is considered in the problem of the wave-seabed interaction in a porous seabed of finite thickness.
