Abstract
In this paper, model test on the Tapdong's revetment at Jeju-si has been conducted to figure out the causes of frequent occurrence of wave overtopping and to suggest the action plan. In the model test, the reflection coefficients were measured according to the change of wave periods for with and without armor stones. Also, the wave overtopping rate and the wave pressures inside revetment structure for 4 types of upper block were estimated for various wave heights and wave periods, which are chosen based on the NE design wave with 50 year return period. It is found that the increase of the upper structure's height and the modification of the curved protruding shape are effective in reducing the overtopping rate.
