|Abstract: ||Abstract: In this paper, we investigate the hydrodynamic efficiency
of normal incident waves interacting with an absorbing system.
The wave absorbing system consists of a submerged permeable structure filled with rock, a solid back wall, and a submerged horizontal or slightly inclined porous plate. Using a linear
wave theory assumption, a multi-domain BEM (MBEM) model
was created to calculate and discuss the reflection coefficients,
free surface wave profiles, total wave force on the solid wall,
and the horizontal and uplift forces acting on the porous plate
of the water waves from several properties of the breakwater.
The numerical model was calibrated using previous numerical
studies to act as limiting cases for a partially submerged impermeable structure and a horizontal porous plate with a solid
back wall. The accuracy of the solution is demonstrated by comparing the numerical values with those obtained from other
analytical solutions. From the numerical results, the wave dissipation effect from the permeable rock-filled structure was
found to perform better than expected when compared to an
impermeable structure. In the case of a horizontal porous plate,
the smaller submergence depth of the plate results in a smaller
reflection coefficient. The larger the porous effect parameter,
the smaller the value of the reflection coefficient and the larger
the porous effect parameter, the greater the ability of the porous plate to reduce the uplift forces.
