Abstract
In this research, we develop mathematical model to investigate the effectiveness of embankment and vegetation on the reduction of wave run-up. We solve the model numerically using a staggered finite volume method. Wave run-up test on a sloping beach is conducted to show the accuracy of our numerical scheme. In this case, we compare our numerical results with results of laboratory experiment of Synolakis in 1987. Further, sensitivity analysis is presented to see the effect of the characteristic of the structures.
