The purpose of this study is to clarify the characteristics of wave overtopping on gentle slope-type seawall. Therefore, experiments on wave overtopping by irregular waves were carried out for gentle slope-type seawalls. Using the results, effects of the ratio of the water depth to the wave height, the relative crown height of the seawall, the sea bottom slope and the slope gradient of the seawall on the wave overtopping rate of gentle slope-type seawalls were discussed. And, an optimum combination between slope gradient of the seawalls and sea bottom slope was examined from the wave overtopping prevention of view. In addition, frequency of appearance distribution of wave overtopping rate was also investigated.
