Abstract

This paper studies, numerically, the validity of different wave height distributions and the minimum number of components needed to validate the distribution under study. Also, the effect of bandwidth of the wave spectrum is considered. Rayleigh distribution, the modified Rayleigh distribution and the Beta- Rayleigh distribution are considered in this study Introduction It was proved analytically that, if the sea surface elevation can be represented by a sum of an infinite number of harmonic components uniformly distributed about a central frequency and having the same amplitude., then the wave height can be represented by Rayleigh distribution, assuming that the bandwidth of the wave energy spectrum is narrow. It is not clear what is meant by narrow band spectrum. More clearly, what is the limit of the bandwidth that allows Rayleigh distribution to re
