Abstract

The study was made on the effect of wave group interaction on the distribution of wave height. The interaction of two wave groups was studied on the basis of coupled nonlinear Schrödinger equations. We found that wave group interaction may cause the deviation of wave height distribution from the result of linear theory. For low and medium wave heights, in the case of nonlinearity the probability of exceedence is higher than the result of linearity. For waves with large height, in the case of nonlinearity the probability of exceedence is lower than the result of linearity. From average wave height to 1.5 times this height is the transition region. The result is in consistency with that of wind wave experiment. A parameter was introduced in studying the influence of wave group interaction on wave height distribution. It is a measure of the effect of nonlinearity on the distribution. For wind waves this parameter reflects the shape of the spectrum. The spectral shape is found to be an important factor in influencing the distribution of wave height.
