Effects of spectrum band width on the distribution of wave heights and periods

A theoretical expression for the joint distribution of crest-to-trough wave heights and zero up-crossing periods is developed from a modified extension of presently available results relevant to wave envelopes and periods under narrowband conditions. The resulting probability structure, in particular, the marginal density for crest-to-trough heights is explored explicitly with respect to effects associated with the spectrum band width. Results are given to show that the Rayleigh distribution, which is often used in predicting crest-to-trough heights, can not be regarded as accurate. The analysis is extended further to restate and establish the validity of an approximate expression for the distribution of crest-to-trough heights, which was suggested in a previous study.
