Wave overtopping discharge on rubble mound breakwaters influences the rear slope stability as well as safety of operations and installation on and behind the breakwater. Typically, the overtopping discharge is measured on the rear part of the crest, but rear slope stability might also be dependent on the water passing through the crest. For studying operations behind the breakwater most important is the overtopping over the crest. The influence of crest permeability on the wave overtopping has so far not been fully understood. In the present paper, the influence of a permeable crest is investigated trough new model tests.
