Secondary Pressures of Waves Breaking on Seawall
TLDR
In this paper, the second peak pressure is studied experimentally with beaches having four different slopes and the authors found that the magnitude of second peak pressures is much lower than those of the first peak pressures.Abstract:
Secondary pressures resulting from the waves breaking on a vertical wall are studied experimentally with beaches having four different slopes. Pressure history of the wave impact consists of two distinct parts: The first peak and the second peak. The magnitudes of the second peak pressure are found to be much lower than those of the first peak pressures. The duration of the second peak pressure is considerably longer than the first peak pressure. The vertical distribution of simultaneous second peak pressure is almost linear vertically and this pressure is somewhat similar to a hydrostatic pressure. The major parameter affecting the second peak is the initial wave steepness. The effective pressure head is about the wave crest for low waves and moves below it for steep waves.read more

Breaking wave loads at vertical seawalls and breakwaters
TL;DR: In this article, the authors present recent advances in knowledge on wave loads, based on experimental work carried out in the CIEM/LIM large flume at Barcelona within the framework of the VOWS (Violent Overtopping by Waves at Seawalls) project.

Breaking wave impact on vertical and sloping coastal structures
TL;DR: In this article, the maximum and bottom impact pressure on a wall is treated statistically and the effects of the wall angle and foreshore slope on these two quantities are examined, and the results show that for practical applications, the still-water level can be taken as the acting place for the maximum pressure on the wall.

An experimental investigation of a vertical wall response to breaking wave impact
TL;DR: In this article, the authors measured the impact pressure and resulting wall deflection from breaking oscillatory waves on a vertical wall with 1/10 foreshore slope and found that the longerlasting low impact forces are more effective in producing the larger wall deflections.

Evaluation of wave impact loads on caisson breakwaters based on joint probability of impact maxima and rise times
TL;DR: A new approach to the definition of loads for use in performance design of vertical coastal structures subject to breaking wave impacts is presented and predictions of static equivalent design loads and corresponding safety factor against sliding using the proposed methodology are found to be in very good agreement with both predictions by most established deterministic methods and field observations reported in literature.

Impact pressure of breaking waves on vertical and sloping walls
TL;DR: In this article, the authors measured the impact pressure of breaking waves on vertical, 5° forward, and 5, 10, 20, 30, and 45° backward sloping walls.

Shock pressure of breaking waves on vertical walls
TL;DR: In this paper, the authors studied the impact of a breaking wave on a vertical wall with four different slopes and found that a wave having its front face parallel to the wall at the instant of impact produces the greatest shock pressures.

Shock pressure of breaking wave
TL;DR: In this article, a new air-cushion model was proposed to explain the observed properties of shock pressure, in which the new model extended from the original air cushion model of Bagnold (1939) was included.

Wave Action: In Relation to Engineering Structures
TL;DR: A PAPER on wave action in relation to engineering structures, by Major D. D. Gaillard, issued as a professional paper (No. 31) of the Corps of Engineers of the United States Army, contains a great deal of information useful to engineers engaged in designing and constructing sea defences and other works subject to wave action as mentioned in this paper.
