Wave pressure reduction due to a submerged horizontal plate placed before a vertical wall was investigated both numerically as well as experimentally. Pressure-reduction due to the submerged plate for short period waves was clearly evident. For all the case studies, the optimal submergence depth was found to be equal to d = 0.20h rather than 0.45h, where h is the total water depth. However, at this depth, d = 0.20h, the pressure-reduction effect will vary according to wave conditions, the width of the plate, (l), and the distance of the plate away from the vertical wall (w). Furthermore, it was found that the wider the plates, the longer the waves that will be affected. Calculated reflection coefficients were found to be in satisfactory agreements with experiments for nonbreaking waves.

Boundary element method (BEM) is used to study wave pressure acting on a vertical quay, as well as the uplift forces on a submerged plate. The plate, placed in front of the quay, is bored with holes. The results are then compared with the case of a plate without any perforation. The results showed that: for q/h = 0.45, where q is the depth of submergence of the plate and h is water depth, wave pressure acting on the vertical quay is very similar for plates with or without borings. However, with q/h = 0.20, wave pressure on the quay is changed according to wave periods, widths of the plate, the distance of the plate away from the quay, as well as the ratio of the holes to the plate. Uplift forces exerted on the plate are indeed smaller for plates with borings than without, and decrease with increasing porous ratio. Furthermore, the uplift forces will be the same for the same porous ratios, regardless of these ratios being caused by a single or a double perforation.

Predicting the wave height from the subsurface wave pressure based on the pressure response factor and the correction factor has fundamental difficulties. The relationship between the measured wave height and the subsurface wave pressure was directly assessed in this study without resorting to the two parameters. Laboratory experiments were performed under various wave conditions. An empirical expression of the transfer function between wave height and wave pressure was obtained from these test data by dimensional analysis and regression analysis. In intermediate and deep water depth conditions, the transfer function was only a function of a nondimensional parameter which is composed of the angular frequency, the depth of the pressure sensor under the still water level and the acceleration of gravity. Finally, the empirical expression was compared with the experimental data and observational data from Hom-ma et al. (1966), Cavaleri (1978), Lee and Wang (1984), and Bishop and Donelan (1987). The empirical formula was found to be in sufficient correlation with these data.
