Wave Motion and Seabed Response around a Vertical Structure Sheltered by Submerged Breakwaters with Fabry–Pérot Resonance

This paper presents the results from a numerical simulation study to investigate wave trapping by series of trapezoidal porous submerged breakwaters near vertical breakwater, as well seabed response around breakwater. An integrated model, based on volume-averaged Reynolds-averaged Navier–Stokes (VARANS) equations is developed simulate flow field, while dynamic Biot’s are used for simulating wave-induced response. The reflection energy over breakwaters, caused can be reserved, indicating that existence in front breakwater either provide shelter or worsen hazards Numerical examples show two different modes under Fabry–Pérot (F–P) resonance condition transformation, namely (Mode 1) and 2). distance between key parameter dominating local hydrodynamic process resultant stresses indicated more higher porosity will obviously dissipate energy, hence induce smaller force rear liquefaction area
