Rock Armor Stability
Most rubble mound breakwaters are built in depth-limited breaking wave conditions. When the largest waves break before reaching the structure, most design formulas given in the literature for rock armors are not fully valid. This study focusses on the hydraulic stability of rock armors in the depth-induced breaking zone. Experimental measurements were taken without the structure, and SwanOne software was used to estimate the depth-limited incident breaking waves. Hm0 was a better wave height descriptor than H2% to estimate rock armor damage in depth-limited breaking wave conditions. The stability number (Ns) has a sixth-power relationship with dimensionless armor damage.
