Abstract

Different wind wave spectrum representations for shallow water are compared from a parametric point of view, including formulations with both constant (TMA and FRF spectra) and variable (Wallops-SW and GLERL spectra) frequency exponents. The results of the research clearly show the necessity of at least four parameters in order to achieve an adequate representation of the full range of the spectrum in non-saturated or decaying seas propagating in shallow water. Furthermore, when the modelling of the high frequency range is not of special interest, the total number of independent parameters could be reduced to only three without considerable loss of accuracy. Comparisons of theoretical shallow water spectral forms with s
