Abstract: In this paper, it has been studied using simulation to investigate the effect of berm width on wave run-over over berm breakwaters using a computer-aided design (CAD) and Computational Fluid Dynamics (CFD) software. The direct application of the Navier-Stokes equations in the berm width, is used to provide a more reliable approach to simulating the wave-run over Berm breakwaters. A well-tested Reynolds-averaged Navier-Stokes (RANS) Volume Fluid (VOF) code (Flow-3D) was adopted for CFD computations. The computed results were compared with theoretical data to verify the validity of the model. Numerical results showed that simulation method can provide accurate results for wave bump breakwaters. The main variables are in the simulation: berm width, slope, front breakwater, period and wave height response, depth of stagnation. A total of 320 tests have been performed to cover the impact of these parameters. After review, it was shown that the structural parameters of the berm width have influenced the hydraulic parameters such as the wave wind and due to increased berm width, waves run-up decreases. Also, the wave height and period increases, the amount of wave run-over over berm breakwaters will increase.
