Abstract


In the present study, wave interaction with a fixed, partially immersed, vertical-inclined, thin breakwater (TB) is investigated numerically. Numerical results concerning wave transmission, reflection, dissipation for the vertical thin barrier case are well compared with experimental results by Isaacson et al. (1998), (impermeable-permeable thin breakwater) revealing the credibility of the wave model. Three different draughts of the vertical structure are examined for a range of wave conditions in order to study the effects off the breakwater geometry and wave conditions.. The effects of the inclination of the breakwater on its hydrodynamic characteristics (wave transmission, reflection, dissipation, velocity and turbulence kinetic energy) are also investigated. Computed velocities and turbulence kinetic energy in the vicinity of the structure indicate the effects of the breakwater inclination on the flow pattern and the turbulence structure.
