CFD Simulations of Wave Propagation and Shoaling over a Submerged Bar

The wave propagation over a submerged bar is simulated using the open source CFD model REEF3D and the numerical results are compared to the experimental data. The transformation of the wave resulting in higher harmonics in the wave train is observed as the wave propagates over the crest of the bar. The difference between the wave transformation processes for two different incident wave heights is studied. The higher incident wave height shows more shoaling than the lower incident wave height. The numerical results show a good agreement with the experimental data.
