Scaling the Weight of Breakwater Armor Units

Publication: Journal of Waterway, Port, Coastal, and Ocean Engineering
Volume 111, Issue 3

Abstract

The use of the stability parameter for calculating the weights of armor units in models of rubble mound breakwaters is shown to have little justification. An alternative scaling method based on similarity criteria is developed and the results of the two methods are compared. It is shown that the use of the stability number causes little error but that this is fortuitous rather than physically meaningful.
