Muraleedharan, G., Lucas, C. and Guedes Soares, C. (2023), Spectral wave energy period and peak period statistics concomitant with maximum significant wave heights, Coastal Engineering, Vol. 183, 104260
For this investigation, we employ maximum significant wave heights associated spectral wave energy periods off Aguçadoura (41.46°N, -8.85°W), off Portugal in the North Atlantic Ocean, which were generated over a period of 34 years (1979–2012) by the wave model (SWAN). Conditional Mean Functions of generalised Pareto, Erlang, and three-parameter Weibull distributions are taken into account to determine the distribution of wave energy period. The values computed from the SWAN model data are reasonably coherent with the mean, mean maximum, and most frequent maximum energy periods, as well as the average of the one-third and one-tenth of the highest energy periods projected from the models. The generalised Pareto distribution is used to develop a parametric relation (based on order statistics) that can be used to accurately predict the average of one-third of the highest wave periods. Substantial linear functional relationships exist between computed besides estimated energy period versus peak period statistics. The average of one-third of the highest energy periods to mean energy periods accurately depicts the empirical ratio of significant wave period to mean wave period of 1.2. Daily maximum significant wave heights and associated spectral wave energy periods and peak periods by WAMAN (Wave monitoring along nearshore) wave rider buoy off Kozhicode (11.2698°N, 75.6722°E), southwest coast of India in the Arabian Sea during the winter season (January 2018 to April 2018) are also subjected to Conditional Mean Function Analysis. The sample values are consistent with the population estimates of the mean and the average of the one-third of the highest wave periods. An attempt is made to approximate the range of peak periods associated with extreme significant wave heights by taking into account the steepness constraints of a wave profile and dispersion relations for spectral peak periods.
