TLDR
In this paper, it was found that the spectra of the transmitted waves are generally quite different in total energy and in the frequency-wise distribution of the energy compared to the incident wave spectra.Abstract:
The results of this study have important application to the design of small boat marinas protected from incident waves by breakwaters that may be overtopped during extreme wave events. This overtopping results in transmitted waves with significantly different characteristics than the incident waves. Experiments were conducted with two different breakwater sections, regular and irregular waves, and with several depths representing storm surge effects. It was found that the spectra of the transmitted waves are generally quite different in total energy and in the frequency-wise distribution of the energy compared to the incident wave spectra. The important frequencies associated with the transmitted wave are up to twice that of the incident waves. The transmission characteristics for both regular and irregular incident waves are best defined by the root mean square of the wave amplitudes.read more

Wave parameters after smooth submerged breakwater
TL;DR: In this paper, the influence of short and long waves generated after submerged smooth structure on temporal analysis has been investigated, and it was concluded that long and short waves do not significantly influence the temporal analysis of periods.
Modelling of Wave Overtopping over Breakwater
F. Zhuang,C. Chang,J.J. Lee +2 more
TL;DR: In this article, the authors developed and implemented a numerical model for the generated velocity field in the vicinity of the shoreward face of the breakwater, which consists of two basic elements: the velocity field generated by using the potential flow theory utilizing boundary element method and the rotational velocity fields generated by the separated flow of the overtopping waves as they leave the break-water site using vorticity stream function formulation.

Transformation of statistical and spectral wave periods crossing a smooth low-crested structure
TL;DR: In this paper, a smooth submerged breakwater in a wave channel was studied to study the impact of relative submersion on the changes of statistically and spectrally defined representative wave periods as waves cross it.
