| Outline of Final Research Achievements |
This study proposed a model equation to estimate a maximum wave overtopping rate, a significant wave overtopping rate and an averaged wave overtopping rate under wind blowing conditions. This study also evaluated the applicability of the model equation by comparing the calculated results with the measured ones that were obtained in a series of hydraulic experiments. This study confirmed that the model equation estimates those rates with good correlation in the case of an upright seawall. On the other hand, the model equation estimated the maximum wave overtopping rate with poor correlation in the case of a flared type seawall, though the equation estimated the significant wave overtopping rate and averaged one with good correlation. There is a difference in the behavior of wave uplift in front of each seawall, and the applicability of the proposed equation was affected by the correlation between the model coefficient and the wave overtopping increasing coefficient.
