영문 초록

A new method treating maximum wave height as random variable was proposed. The ratio of maximum wave height to significant wave height is defined as a new random variable in this study. Then, maximum wave height is expressed as a multiplication of the ratio by significant wave height. It was shown that probability density function (PDF) of the wave height ratio derived from non-breaking wave environment can be also used in describing statistical behavior of breaking waves if appropriate shape parameter for the PDF is used. It was also shown that a shape parameter can be numerically obtained by analyzing a series of waves generated by two phases Rayleigh distribution. In addition, PDFs of maximum wave height according to significant wave heights were derived, presented and compared. Some examples were used to show how those findings are reliable.
