Non-Gaussian Properties of Waves in Finite Water Depth.
Abstract
As waves propagate into shallower waters, their profile changes from a Gaussian distribution to an increasingly non-Gaussian profile. The non-Gaussian properties of waves in finite water depths are analyzed through the use of a probability density function defined in closed form and that can be solved by the application of wave displacement data. Initially, the applicability of the probability density function is verified using wave data records obtained from the Coastal Engineering Research Center (CERC) at Duck, North Carolina. A broad range of sea conditions and water depths are represented to ensure the probability density function correlates well with actual histogram data over varied conditions. With the applicability verified, the probability density function is used to define criteria for the boundary where the wave field can no longer be considered Gaussian. The ability to determine when a shoaling wave profile can no longer be considered Gaussian is of paramount importance in order to ensure proper wave theories are being applied. This boundary between Gaussian and non-Gaussian wave profiles will be determined in terms of significant wave height and water depth.
