A numerical model based on multi-domain boundary element method (BEM) is developed to study the gravity wave interaction with a horizontally submerged wavy porous plate. The boundary condition on the porous barrier is considered a quadratic pressure drop to incorporate the effect of wave height on the wave energy dissipation directly. The performance characteristics of the wavy porous plate are studied by analysing the hydrodynamic coefficients of the breakwater for different physical parameters. Numerical results demonstrate that wavy porous plate improves the energy dissipation and reduce wave transmission compared against the conventional flat plate. The increase in wave energy dissipation is governed by the ripple amplitude and the number of ripples. The proposed model is expected to act as an effective wave barrier in the attenuation of wave energy for the creation of a tranquillity zone in the marine environment for water depths ranging from intermediate to deep waters.
