Wave transmission coefficient reduction by wooden fences

In this study, we investigate the efficiency of wooden fences in reducing wave amplitude using a modified version of the Linear Shallow Water Equations. The resulting model is solved analytically and numerically to obtain the wave transmission coefficient. We apply a staggered finite volume method to obtain the numerical solution of the model, which is subsequently validated through comparison with the analytical solution of the equations and experimental data from a previous study. The validated scheme is then employed to simulate the wave attenuation of wooden fences. We anticipate that this method will prove valuable in the construction of coastal defense systems, particularly for the protection of mangroves. •A shallow water equation has been successfully used to investigate wave attenuation by wooden fences.•An analytical wave transmission coefficient is obtained using separation variable method.•This coefficient is inversely proportional to the friction factor cf and the thickness of wooden fences.•This wooden fences are proven to able to reduce wave height that is useful to protect mangroves.
