Abstract

The evolution of waves and wave-induced currents over porous submerged breakwaters is studied by applying a numerical model based on a truncated version of Chen (2006) Boussinesq-type equations for waves and currents over porous bottoms. The equations of motion for the porous medium include an empirical Forchheimer-type term for laminar and turbulent frictional losses and an inertial term for acceleration effects following Sollitt and Cross (1972). Comparisons between simulations and new set of laboratory experimental data show excellent agreement for wave field in one-dimensional horizontal wave propagation and qualitatively good agreement for wave and current field in horizontal two-dimensional wave propagation.
