In this paper, a linear Lagrangian numerical model is used for simulating the solitary wave propagation over the sloped sea wall, as well as the regular wave propagation over an Impermeable submerged breakwater, called the relatively compact (GCM) hydrodynamic model of relatively compact particles (WCSPH). To simulate fluid turbulence, the SPS turbulence model, which was obtained by large eddy simulation (LES) approach, was used. The results of numerical simulations were compared with laboratory experiments. Also, the results of present numerical model were compared with the numerical model Shen et al. (2004). The results shown, the WCSPH computations produce better results than those of model Shen et al. (2004), with respect to the experimental data. The results of this study show that WCSPH method provides a useful tool to investigate the wave propagation over coastal structures.

In this paper, a linear Lagrangian numerical model is used for simulating the solitary wave propagation over the vertical coastal wall, as well as an Impermeable submerged breakwater, called the relatively compact (GCM) hydrodynamic model of relatively compact particles (WCSPH). This model is two-dimensional and considers the fluid to be weakly compressible. In addition to solving theviscous fluid governing equations for velocity and density field uses the state equation for obtaining the pressure. This reduces the computational volume compared to the base method of the particle hydrodynamic model. To simulate fluid turbulence in the wave propagation process on an impermeable submerged breakwater and vertical seawall the SPS turbulence model, which was obtained by large eddy simulation (LES) approach was used. The results of numerical simulations were compared with laboratory experiments. Also, the results of present numerical model were compared with the numerical model of Rambabua and Mani (2005). The results shown, the WCSPH computations produce better results than those of model of Rambabua and Mani (2005), with respect to the experimental data. The results of this study show that WCSPH method provides a useful tool to investigate the wave propagation over coastal structures
