dc.description.abstract The spectral characteristics of shallow water waves with significant wave height more than 2m based on the data collected along the Indian coast are examined. It was found that the value of Joint North Sea Wave Project (JONSWAP) parameters (alpha and lambda) increases with significant wave height and mean wave period and decreases with spectral peak period. The estimated average value (0.0027 and 1.63) of the JONSWAP parameters, alpha and lambda were less than the generally recommended values of 0.0081 and 3.3, respectively. By carrying out a multi-regression analysis, an empirical equation is arrived relating the JONSWAP parameters with significant wave height, peak wave period and mean wave period. It was found that the Scott spectra underestimate the maximum spectral energy of high waves. The study shows that the measured wave spectra can be represented by JONSWAP spectra with the JONSWAP parameters estimated based on the equation proposed in this paper.
