Overtopping of rubble mound breakwaters by random wave action

Prikazani su analitički modeli prelijevanja lukobrana slučajnim valovima s detaljnijom analizom Owenova modela i modela Hedgesa i Reisove. Prema ovim su modelima izvedeni izrazi za visinu krune lukobrana u funkciji dopuštenog prelijevanja, parametara lukobrana i valne klime. Pokazano je da razlike prema ovim modelima nastaju zato što se Owenovim modelom ne da odrediti nulto prelijevanje ako je visina krune veća od valnog uspinjanja, što je zadovoljeno u modelu Hedgesa i Reisove.Analytical models of overtopping of breakwaters by random wave action are presented, and a particular emphasis is placed on the Owen\u27s model and the model developed by Hedges and Reis. These models served as a basis for deriving expressions for breakwater crest height as a function of allowable overtopping, breakwater parameters and wave climate. It is demonstrated that differences between these models are due to the fact that zero overtopping can not be determined by Owen\u27s model if the crest height is greater than the wave elevation, which has been resolved in the model presented by Hedges and Reis
