### Abstract

A numerical scheme has been developed to simulate the propagation of water waves over a rigid porous bed. The governing equations for the fluid in the water region are the Navier-Stokes equations. In the governing equations for the motion of a viscous fluid in the porous bed, both the inertial and viscous forces are taken into account. The boundary conditions on the free surface and at the interface of the water and the porous bed are exact. The incoming waves were generated by a piston type wavemaker set up in the computational domain. The numerical results were verified by comparison with the experimental data. The main characteristics of the flow fields in both the water region and the porous bed are discussed by specifying the velocity fields. The effects of a dimensionless parameter, which represents the ratio of the interfacial force to the inertial force acting on the porous fluid, on the wave height attenuation were studied and discussed.

N2 - A numerical scheme has been developed to simulate the propagation of water waves over a rigid porous bed. The governing equations for the fluid in the water region are the Navier-Stokes equations. In the governing equations for the motion of a viscous fluid in the porous bed, both the inertial and viscous forces are taken into account. The boundary conditions on the free surface and at the interface of the water and the porous bed are exact. The incoming waves were generated by a piston type wavemaker set up in the computational domain. The numerical results were verified by comparison with the experimental data. The main characteristics of the flow fields in both the water region and the porous bed are discussed by specifying the velocity fields. The effects of a dimensionless parameter, which represents the ratio of the interfacial force to the inertial force acting on the porous fluid, on the wave height attenuation were studied and discussed.
