Interaction of Wind Waves With Vertical Wall
Publication: Journal of Waterway, Port, Coastal, and Ocean Engineering
Volume 114, Issue 5
Abstract
A modification of the linear wave theory of the interaction between wind‐induced waves and an infinite vertical wall is presented. As the free surface fluctuates with time, a point fixed in space in the vicinity of the mean water level is not submerged at all times but emerges from the water in some phases of the wavy motion. The modification consists of taking into account this effect, which is referred to in this paper as the emergence effect. Its influence is essential when determining the stochastical characteristics of pressures and forces on the vertical wall. Numerical results for the mean value and variance of the dynamic pressure and force induced by wind waves are obtained and presented graphically. Comparisons are made with the case in which the free surface fluctuation phenomenon is ignored. Inclusion of the free surface fluctuation phenomenon appreciably changes the mean value and variance of the pressure and force relative to the unmodified theory. The difference is most pronounced at points near the mean water level.
