Based on Forchheimer equation and potential theory, the propagation of small amplitude surface waves over a permeable bed is examined. The special linearization technique that is based on the assumption of the equivalent work (Lorentz' hypothesis) is employed in order to determine analytically the velocity field and pressure field. Demanding the continuity of pressure and velocity components at the interface, the damping factor and wave number for arbitrary permeability are found. The example calculations show that the influence of the permeability on the pressure distribution is negligibly small.
