Modelling Linear Water Waves with porous media

I'm fairly new to COMSOL Multiphysics so I apologise for my ignorance.
I am wanting to model linear water waves passing over/through porous media (e.g. a porous breakwater). I was given a model that uses both Moving Mesh (ALE) and the Incompressible Navier-Stokes (ns) application modes. However, I am unable to see where to put parameters such as porosity.
I would like to achieve something similar to Martinelli found at: www.comsol.com/papers/1564/
However I would like the breakwater to be fixed, submerged and to be porous.
I have also noticed that the Earth Sciences module has Brinkman Equations which state they can be used for modelling porous media. I have tried this application mode to no avail and get the error message "Failed to evaluate expression for manual time step".
I was wondering if the Incompressible Navier-Stokes application mode (under COMSOL Multiphysics > Fluid Dynamics) could be used to model a porous breakwater?
Thank you in advance!
