Smoothed Particle Hydrodynamics (SPH) is an attractive mesh free numerical method for simulating nonlinear wave structure interaction problems. This paper presents a comparative study between weakly compressible and truly incompressible SPH schemes for violent wave impact on fixed structures. For this purpose, the well known benchmark problem of two-dimensional (2D) dam break flow has been considered. The Pressure Poisson Equation (PPE) in the Incompressible SPH (ISPH) scheme utilizes a mixed source term, which has evidently improved the numerical stability. A 2D Numerical Wave Tank (NWT) is developed based on Weakly Compressible SPH (WCSPH) scheme to study wave impact due to interaction of nonlinear water waves with a vertically composite breakwater.
