A description is given of a model for the prediction, in a sea state, of the onset and the fraction of impact waves on simple vertical and composite breakwaters. The starting of impacts is estimated by defining a local maximum wave height, Hbc. The percentage of breaking waves is based on the number of waves which, according to the Rayleigh distribution, would have been larger than Hbc. For the approximations introduced, the predicted fraction of breaking waves should be considered as an upper limit for the percentage of impacts. The validity of the model is confirmed by 191 irregular wave experiments.

Abstract
A description is given of a model for the prediction, in a sea state, of the onset and the fraction of impact waves on simple vertical and composite breakwaters. The starting of impacts is estimated by defining a local maximum wave height, Hbc. The percentage of breaking waves is based on the number of waves which, according to the Rayleigh distribution, would have been larger than Hbc. For the approximations introduced, the predicted fraction of breaking waves should be considered as an upper limit for the percentage of impacts. The validity of the model is confirmed by 191 irregular wave experiments.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
