Available in PDF, EPUB and Kindle. Book excerpt: Recent advances have been made in the specification of a shallow-water self-similar spectral form. This spectral form, referred to as the TMA spectrum, substitutes an expression for the shallow-water equilibrium range into the JONSWAP equation for spectral energy density. The JONSWAP parameters are empirically defined through examination of over 2,800 wind sea spectra obtained at various depths and locations. This spectral form is intended to describe single-peaked wind seas which have reached a growth equilibrium in finite depth water. The purposes of this report are to summarize the recent advances, to discuss the range of practical usage, and to provide engineering examples using these new formulations. (Author).
