Influence of Wave Groups on Stability of Berm Breakwaters
Publication: Journal of Waterway, Port, Coastal, and Ocean Engineering
Volume 120, Issue 6
Abstract
The effect of wave groups on the stability of berm breakwaters was assessed in a two‐dimensional wave flume. Profiles of the structure during the various stages of reshaping were measured using a profiler developed for this study. Four gradations of armour stones were used, giving a range of uniformity coefficients () of 1.35‐5.4. The volume of stones and the initial berm width required for development of a stable profile and the extent to which the toe of the structure progressed seaward were chosen as representative parameters of the reshaped breakwater. These parameters were found to be insensitive to changes in wave groupiness factor ranging from 0.5 to 1.1. These conclusions apply to the model results undertaken for a structure having a .
