ABSTRACT: Based on double peak wave spectrum model, this paper studied three types of mixed waves of wind and swell including wind-dominated mixed wave, mixed wave of wind and swell in equal strength, and swell and swell dominated mixed wave, analyzed the spectrum morphological characteristics of the three types of mixed waves, established the random wave model, and simulated two-dimensional wave and three-dimensional wave, respectively. Moreover, the effect of water depth on waveform was researched, and the results showed that the wavelength was significantly reduced as the water depth was reduced to some extend. This paper concluded that the random wave model based on double peak wave spectrum can effectively simulate mixed wave with different ratios of wind and swell.
