ESTIMATION OF OVERTOPPING RATES ON SLOPES IN WAVE POWER DEVICES AND OTHER LOW CRESTED STRUCTURES

Motivated by questions raised by developers of wave energy devices based on wave overtopping concepts, model tests have been performed to study overtopping of structures with limited draught, low crest freeboards and slope geometries designed to increase overtopping and thereby also the captured amount of wave energy. The test results have been incorporated in an existing overtopping prediction formula by application of correction factors presented in the paper.
