Investigating spectral and experimental methods in predicting wind waves in the southern regions of Iran (case study: Asalouye port)

sea level rise due to wind are one of the most important phenomena in marine environments that are effective in the coastal and offshore processes. This paper discusses methods to evaluate the accuracy of experimental and spectral methods in predicting wind waves in Asaluyeh port. Empirical methods including SMB, SPM, CEM and Jonswap and Spectral methods include Bretschneider, Mitsuyasu, Pierson-Moskowitz, Jonswap, ISSC spectrum were considered to evaluted the mentioned waves. The results show that Jonswap method among experimental methods in duration of ۶ hours is the most appropriate method to determine the wave profile in Asaloyeh port. Furthermore by comparing spectral methods it was found the Bretschneider, Mitsuyasu and Pierson-Moskowitz spectrum show lowest error in the calculation of Hm۰ nd fp. To better match the measured spectra, their coefficients were corrected and after height value was calculated using each spectrum. Then, using corrected and uncorrected spectra, directional spectra of the region were plotted.
