Nonlinearities due to second-order bound waves do not, on average, affect the statistics of large wave heights. Heights of waves representing approximately the largest 1/3 of waves are described quite accurately, in particular, by Boccotti's asymptot

Modulational instabilities induced by third-order nonlinear interactions among freely propagating waves can cause the statistics of various surface features to deviate significantly from the predictions based on the linear Gaussian and second-order m

We present a second-order stochastic model of weakly nonlinear waves and develop theoretical expressions for the expected shape of large surface displacements. The model also leads to an exact theoretical expression for the statistical distribution o

Theoretical distributions proposed for describing the crest-to-trough heights of linear waves are reviewed briefly. To explore the effects of nonlinearities, these are generalized to second-order waves, utilizing quasi-deterministic results on the ex

Groups of large nonlinear waves with sharper higher crests can pose hazards to ships, induce harbor resonance and cause wave-overtopping of fixed and floating structures. Past interest in wave groups has mostly been focused on the statistics and mode

Predictions of wave action on slopes, and various wave- and depth-induced processes in the surf zone rely on two principal parameters: Wave steepness and surf parameter. For irregular waves, the theoretical distributions of these parameters are not k

The least-upper-bound (lub) theory recently proposed by Tayfun and Al-Humoud as a model for the statistical distribution of nonlinear wave crests is explored further. The theoretical distribution of the lub to the largest crest in N waves is also con

The exact form of the statistical distribution of nonlinear wave crests is not known. This study proposes and develops a theoretical least upper bound (lub) distribution for large crest heights within the framework of second-order deep-water wave the

The representation of directional random waves in deep water under locally homogeneous conditions is examined in terms of the effect of second‐order nonlinearities on the wave envelope and phase. Theoretical expressions describing the joint, margin

This paper investigates the effect of third-order nonlinearities on the statistical distributions of wave heights, crests, and troughs of waves mechanically generated in a deep-water basin and simulating two crossing systems characterized by bimodal
