Spectral analysis of wind waves using field data in Strait of Hormuz

Abstract

Present study consists the analysis of extreme wind wave spectrum in Strait of Hormuz. Data was measured by Port and Maritime organization from 2009 to 2011 in “Monitoring and Modeling Study of Coastal Zone of Persian Gulf” project framework. Wave measurement instrument type was AWAC under sea equipment which has been implanted at 25m depth. Data records analyzed by computer program in STORM, MATLAB and SPSS environments for quality controlling and identifying wave spectrum characteristics like spectrum dispersal, directional spectrum, multi peak spectrum, spectrum shape, parameters of spectrum and spectral classification. Model parameters of JONSWAP and PM spectra were estimated for the observed spectra by using the least square error method.
