While waves diffracted on breakwaters and multi-reflected in a harbor area act on harbor facilities, it may be difficult to estimate the progressive wave height on quay wall, which is applied to Goda formulas of wave pressure. In design of the parapet installed on quay as a countermeasure for inundation due to wave overtopping, estimation of vertical distribution of wave pressure must be required on stability check as same as design of breakwaters. Therefore, in this study, the vertical distribution of wave pressure is directly calculated by using a Boussinesq model (NOWT-PARI Ver5.2), which is widely used for harbor tranquility analysis in abnormal wave condition.
Although a newly developed wave pressure equation which is installed in the Boussinesq model can estimate the vertical distribution of dispersive wave pressure, it is realized that the model overestimates one of nonlinear standing wave pressure overall and especially around water surface and must be modified in detail to estimate wave power limitedly acting on the parapet located above settle water surface.
