Abstract
In this paper, we investigate wave damping caused by breakwater and mangrove using Shallow Water Equations. To derive the wave transmission coefficient, we solve the model analytically using the separation of variables approach. To solve the problem numerically, we use a staggered finite volume approach. We validate our numerical result by comparing it to the analytical solution. Furthermore, we investigate the effects of the dimension and characteristics of the breakwater and mangrove in reducing incoming wave height. We believe that this finding will aid engineers in designing the coastal protector.
