TL;DR: In this article, the second-order, three-dimensional, finite-depth wave theory is used to investigate the statistical properties of the surface elevation and wave crests of field data from Lake George, Australia.
Abstract: The second-order, three-dimensional, finite-depth wave theory is here used to investigate the statistical properties of the surface elevation and wave crests of field data from Lake George, Australia. A direct comparison of experimental and numerical data shows that, as long as the nonlinearity is small, the second-order model describes the statistical properties of field data very accurately. By low-pass filtering the Lake George time series, there is evidence that some energetic wave groups are accompanied by a setup instead of a setdown. A numerical study of the coupling coefficient of the second-order model reveals that such an experimental result is consistent with the second-order theory, provided directional spreading is included in the wave spectrum. In particular, the coupling coefficient of the second-order difference contribution predicts a setup as a result of the interaction of two waves with the same frequency but with different directions. This result is also confirmed by numerical...

TL;DR: In this paper, exact solutions for rogue waves arising on the background of periodic standing waves in the focusing nonlinear Schrodinger equation were obtained by characterizing the Lax spectrum related to the periodic standing wave and by using the one-fold Darboux transformation.

TL;DR: High-resolution hindcast of hurricane-generated sea states and wave simulations are combined with novel probabilistic models to quantify the likelihood of rogue wave conditions and show that the largest simulated wave is generated by the constructive interference of elementary spectral components enhanced by bound nonlinearities.
Abstract: We present a study on the prediction of rogue waves during the 1-hour sea state of Hurricane Joaquin when the Merchant Vessel El Faro sank east of the Bahamas on October 1, 2015. High-resolution hindcast of hurricane-generated sea states and wave simulations are combined with novel probabilistic models to quantify the likelihood of rogue wave conditions. The data suggests that the El Faro vessel was drifting at an average speed of approximately 2.5 m/s prior to its sinking. As a result, we estimated that the probability that El Faro encounters a rogue wave whose crest height exceeds 14 meters while drifting over a time interval of 10 (50) minutes is ~1/400 (1/130). The largest simulated wave is generated by the constructive interference of elementary spectral components (linear dispersive focusing) enhanced by bound nonlinearities. Not surprisingly then, its characteristics are quite similar to those displayed by the Andrea, Draupner and Killard rogue waves.

TL;DR: In this paper, the wavelet transform over the Fourier transform was used for early detection of rogue waves in a chaotic wave field, and the triangular wavelet spectra of the rogue waves can be detected at early stages of the development of the wave.
