Abstract

The armor stability of composite breakwaters has been investigated by large 3-D model experiments using oblique irregular waves. The characteristics of wave-induced flow near the mound, which directly affect the armor stability, are disclosed theoretically and numerically. The stability number of armor units in breakwater trunk, head and tail sections is formulated for oblique wave angles less than 60°. The applicability of the proposed methods is confirmed by prototype failure data, and the analyses of case studies are shown for some practical conditions.
