Analysis of the Influence of the Different Variables Involved in a Damage Progression Probability Model

“…Some examples on this matter can be found in Carver and Wright (1991), Medina (1992), Medina and Hudspeth (1994), Melby and Kobayashi (1998)... The divider was driven into the bottom ramp and into the retaining wall.…”

Damage prog[r]ession on rubble-mound breakwaters / by Jeffrey A. Melby ; prepared for U.S. Army Corps of Engineers.

“…They simply determined Kp corresponding to the lowest stability condition over a range of typical wave periods. The Hudson equation has been extended to include the effects of irregular breaking and nonbreaking waves and wave period (Ahrens 1975, Ahrens and McCartney 1975, Carver and Wright 1991, SPM 1984, various armor layer types and armor gradation (e.g. SPM 1984), and number of waves (Medina and McDougal 1988).…”

“…Equations 3.7 and 3.8 do not indicate decreasing stability as the depth to wave length ratio decreases and the wave breaking becomes more severe. Carver and Wright (1991) showed that stability decreases dramatically with decreasing relative depth. The minimum stability condition occurs where the wave breaking is characterized by plunging to collapsing breakers at the toe of the structure.…”

Investigation of Wave Grouping Effects on the Stability of Stone- Armored, Rubble-Mound Breakwaters

“…Previous breakwater stability investigations conducted by Carver (1983) and Carver and Wright (1991) have shown that relative depth (d/L) and relative wave height (H/d) ore two of the most important dimensionless variables influencing breakwater stability with minimum stability occurring at the lower values of d/L and higher values of H/d, i.e., longer Chapter 1 Introduction wave periods in shallower water. Therefore, initial tests were conducted with period depth combinations that are in the minimum stability range.…”
