Rubble Mound Breakwater Failure Modes: Failure Mechanisms Observed during Model Tests
Correlations between failure modes of rubble mound breakwaters has been investigated by reviews of existing literature. The main part of the report is given by a description of observed failure mechanisms during model tests performed by DELFT HYDRAULICS. The main conclusions are: the presence of plunging waves caused by a very steep foreshore and landing on the toe structure led to huge toe structures that have to protect the armour layers; the geometry of the transition from the crest structure to the rear slope influences the stability of the crest structure; the geometry of the crest structure itself is important for the rear slope stability. Design criteria for rear slopes of berm breakwaters are given. Further, the destruction of a breakwater without a crest element, failure of a 90t blocks rear slope, and a composite breakwater is treated.
