In this study, an investigation is carried out to analyze the interaction between water waves and rectangular porous breakwater placed over sloped and impermeable seabed under the influence of ocean currents. By considering two different cases (a) wave scattering (b) wave trapping, the behaviour of different wave transformation characteristics is analyzed in present study. The impact of important physical and structural parameters such as the friction coefficient, sloping angle of the seabed, porosity of the breakwater, and ocean currents to comprehend various phenomena related to wave and breakwater interaction in the presence of the uniform ocean currents is analyzed. The boundary element method-based numerical technique is used to solve the associated boundary value problem. The porosity of the breakwater is modeled using the Sollitt and Cross model (Sollitt and Cross in Wave reflection and transmission at permeable breakwaters, 1972) of water wave passes through thick porous structures. The results demonstrate that due to the shift in incident wave frequencies, there are shifts in the curves of wave transformation characteristics. To assure the stability of the breakwater, the results for wave load also demonstrated with numerous values of structural and physical parameters.
