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

摘要

High sea waves tend to appear in groups rather than individually. Because of thenature of wave grouping, it appears that it may be an important influence on the stability of rubble-mound structures. The research documented in this report was conducted to obtain a better understanding of the effects of wave grouping on the stability of stone armor when used on breakwater trunks. Results of this study show stability to be influenced by wave period, spectral width, and wave grouping intensity. Levels of wave grouping tested herein are achievable at some, but not all, prototype locations; therefore, results should be applied on a case-by-case basis.
