. Damage prog[r]ession on rubble-mound breakwaters. Rubble mound breakwaters; Breakwaters; Coastal engineering; Flumes; Hydrodynamics. Figure Photograph of model structures before testing In armor stabihty experiments, breakwater crest heights are usually set high enough to prevent overtopping from influencing the stability, unless overtopping is the focus of the study or the breakwater is low crested. But the composite downslope weight of upslope armor units generally contributes to the stabiUty of the armor layer and increases as the slope lengthens; although under some conditions, longer armor layers can have a tendency to buckle or slide. Just considering stone stability, for a given wave height, taller structures are typically more stable, with respect to main armor stability, than short structures. But, in the prototype, the cost of the breakwater is kept to a minimum by setting the breakwater crest height such that minor overtopping is allowed for a design wave condition. Thus, experimenting with non-overtopped structures that have high crest heights typically will not be conservative with respect to 55.
