This report presents the design method for mild-slope revetment by taking into account the beach evolution model. According to the previous investigations, it has been shown that it was not adequate to construct the mild-slope revetment in the beach where alongshore sediment transport is large.
In the beach investigated in this study, the change of sediment transport along a beach is seasonal. Theleft-lettore, the shoreline changes were surveyed every season over a year. The results were compared with those predicted by one-line theory and then it was clear that the severe beach erosion was induced by the wave height with the return period of 10 years. Finally, it is shown that the structure constructed in the beach side should be designed so as to be safe for the beach erosion due to the wave characteristics mentioned above.
