Abstract: The relationship between significant wave height and period, spectral peak enhancement factor, and directional spreading parameter of large deepwater waves around the Korean Peninsula have been investigated using various sources of wave measurement and hindcasting data. For very large waves comparable to design waves, it is recommended to use the average value of the empirical formulas proposed by Shore Protection Manual in 1977 and by Goda in2003 for the relationship between significant wave height and period. For relatively large waves, the probability density function of the peak enhancement factor γ is expressed as a lognormal distribution, with its mean value of 2.94, which is close to the value in the North Sea. The probability density function of the directional spreading parameter s max is also expressed as a lognormal distribution.
