In this study, violent water induced impact problems are simulated by using incompressible SPH (ISPH) method. In the framework of ISPH method, there are several models, which have different source term in their pressure Poisson equation. The conventional source terms are velocity divergence free formulation called by "Truly incompressible SPH model" and density invariance formulation. In addition, we have proposed a relaxed density invariance formulation incorporated with divergence free term. This formulation is called 'stabilized ISPH' in this paper. Boundary condition using dummy particles with slip condition is introduced to prevent penetration and adjust wave velocity and profile compare to experimental results. The same formulation of the stabilized ISPH including the turbulence model is applied into the impact pressure evaluation for inclined dam break in two and three dimensions. Comparison between the proposed model and experimental results is performed and it has a reasonable agreement.
