Horizontal Wave Pressures Acting on the Crown Wall of Rubble Mound Structure under Monochromatic Wave Conditions: Case for the Same Level as the Freeboard and Armour Height

In Korea, there are no guidelines for estimating the wave pressure acting on the crown wall of rubble-mound structure, so indirect methods are used. The current design method calculates the horizontal wave pressure by Goda’s formula and the reduction factor of Takahashi et al. This method of estimating horizontal wave pressure has not been clearly established. Therefore, it is necessary to develop a method to directly estimating the horizontal wave pressure acting on the crown wall of rubble-mound structure. In this study, a two-dimensional physical model test under monochromatic wave conditions was performed to examine the horizontal wave pressure acting on the crown wall. Using the experimental results, an empirical formula was derived to calculate the horizontal wave pressure under monochromatic wave conditions.
