Laboratory experiments were conducted in the hydraulics laboratory, school of engineering, Griffith University Gold Coast Campus. For the current study, deployed a space-averaged Navier–Stokes approach and laboratory experiments to investigate the time-dependent wave breaking processes are. The developed model is based on the smoothed particle hydrodynamic (SPH) method which is a pure Lagrangian approach and can handle large deformations of the free surface with high accuracy. Then, a weakly compressible version of the smoothed particle hydrodynamics (WCSPH) method together with a large eddy simulation (LES) approach are used to simulate the wave propagation and periodic wave breaking process over an impermeable submerged breakwater. The results of numerical simulations were compared qualitatively with those of laboratory experiments. Overall, good agreement was found between them. Also, the results of present numerical model were compared with the numerical model of Rambabo and Mani (2005). The results show, that WCSPH computations produce better results than those of Rambabo and Mani (2005), with respect to the experimental data. The results of this study also show that WCSPH method provides a useful tool to investigate the wave propagation over submerged breakwaters.
