Summary: The most important discovery from this investigation was the multiple effects that a pocket wave absorber has in dissipating wave energy. As waves travel past the offset pocket, energy is transported laterally into the pocket via diffraction thereby reducing wave heights in the channel. However, the pocket is more effective at dissipating wave energy than pure diffraction. The pocket dissipates additional energy from the fluid motion over the sloped porous surface. When the waves flow over the sloped stone interface, energy is being dissipated both externally (surface friction) and internally (turbulent flow through the pore space). Results indicate that both contribute to energy dissipation in about the same order of magnitude, but that internal turbulence has a higher degree of variability.
