Cover Story: The work focuses on comparing the effects of the wave spectrum, computed using the discrete interaction approximation (DIA) and the Webb–Resio–Tracy (WRT) methods, on statistical wave properties such as skewness and kurtosis. In addition, the minimum spatial domain size required to obtain meaningful statistical wave properties is investigated. The results indicate that the spatial domain should be at least 10 times the wavelength to obtain meaningful statistical values. The results suggest that selecting a more computationally expensive WRT method does not affect the statistical values to a great extent. The most noticeable effect is due to the energy dissipation filter that is applied. Hence, more accurate energy dissipation mechanisms due to wave breaking are needed. View this paper.
