Breakwater and Revetment Armor Stability

Abstract

This Coastal and Hydraulics Engineering Technical Note (CHETN) provides improved predictive equations for coastal rubble-mound stone-armor stability. The engineering methods outlined apply to breakwaters and revetments exposed to wave loading. The stability equations are based on the concept that the maximum wave force causing armor instability is proportional to the maximum wave momentum flux near the structure toe. This concept introduces a more physics-based first principles approach to estimation of armor stability. The new equations explicitly include the effects of nearshore wave height, wave period, water depth, and storm duration as well as the characteristics of wave breaking on the structure.
