“…The behavior of transmission, reflection, and energy dissipation coefficients in relation to breakwater performance has been investigated in various publications. It has been demonstrated that the porous-effect parameter plays a major role in attenuating wave energy [22], and comparisons between perforated and nonperforated solutions have shown similar hydrodynamic performance in terms of the wave reflectivity coefficient and transmission characteristics [23]. These findings indicate that perforated semicircular breakwaters not only attenuate waves but also create a favorable environment for biological activity.…”

This experimental study investigated the hydrodynamic performance of the first free-surface semicircular breakwater supported on piles under regular waves. The research focused on SCB models with porosity levels of 0%, 9%, 18%, and 27%. Experimental tests were conducted in a wave flume to evaluate the transmission (CT), reflection (CR), and energy dissipation (CL) coefficients of the SCB models. Wave disturbance coefficients (CF) in front of the breakwater and within the breakwater chamber (CC) were also examined. Horizontal wave loading was measured using normalized force coefficients (Fn), including force coefficients of wave crests (Fn,c) and wave troughs (Fn,t). Empirical formulas were proposed to provide a quick estimate of the hydrodynamic performance, showing good agreement with the measured data. The findings highlight the impact of varying porosity levels on wave attenuation, with the impermeable SCB model (0% porosity) exhibiting superior performance compared to the perforated SCB models. This research contributes valuable insights into optimizing SCB model design and enables efficient estimation of its hydrodynamic performance under regular wave conditions. The results provide valuable guidance for the design and implementation of SCB structures, enhancing their effectiveness in wave attenuation applications.

Based on the assumption of linear potential flow theory, the scattering problem of a composite breakwater placed in front of an impermeable back wall is theoretically investigated. The velocity potential in each subregion is found using the eigenfunction expansion method. The boundary conditions of the porous region are treated using Darcy’s law. The semi-analytical solution of a composite breakwater placed in front of an impermeable back wall is then obtained based on the matching conditions of the boundaries of the different regions. The effects of different parameters on the wave loads and wave amplitudes are investigated. In addition, to better understand the performance of the composite breakwater, the scattering problem of the composite breakwater without considering an impermeable back wall is also investigated. The correctness of this theoretical model is verified by comparing the results with previous work. Based on the results of hydrodynamic calculations and analysis of various aspects of a composite breakwater placed in front of an impermeable back wall, the study of the effect of a composite breakwater placed in front of an impermeable back wall allows us to propose a long-term and cost-effective solution for the protection of various marine facilities from wave attacks.
