Effect of Ocean Current on Interaction of Water Waves with Perforated Barrier Placed Over Undulated Seabed

This study examines the dispersion of water waves by perforated surface piercing wave barriers installed over the undulated seabed under the influence of ocean current. The “boundary element method” (BEM) is applied to handle the present “boundary value problem” (BVP). In addition to this, the energy identity is derived to evaluate the dispersion of wave energy by the perforated wave barrier. Furthermore, the influence of porosity, geometrical configurations of the perforated barriers, and the undulation of the seabed on the energy dissipation are investigated. The results demonstrate that the ocean current and Keulegan-Carpenter (KC) numbers play a significant role in wave energy reflection and dissipation.
