The dynamic interaction between waves and coastal structures is an ongoing challenge, and the performance of submerged breakwaters is essential for coastal protection. As physical modeling is costly and complex, this study uses Computational Fluid Dynamics (CFD) to numerically investigate wave behaviour and energy dissipation over a submerged horizontal breakwater with a 0.5-meter head above its crest. The methodology employs the FLOW-3D software, solving the Reynolds-Averaged Navier-Stokes (RANS) equations coupled with the Volume of Fluid (VOF) method for free-surface tracking. The main findings confirm the model's capability to accurately simulate wave run-up and energy dissipation. This demonstrates the utility of FLOW-3D as a dependable, cost-effective alternative to physical experimentation for optimizing submerged breakwater designs and enhancing coastal stability.
