Abstract: 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 = 0.20/;, the pressurereduction 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.
