Performance and limitations of the Hilbert–Huang transformation (HHT) with an application to irregular water waves
Marcus Dätig,Torsten Schlurmann +1 more
TL;DR: In this article, a simple parameter study with trigonometric functions to get an idea about the numerical performance of the empirical mode decomposition (EMD) is performed, and the main results of estimating relative standardized errors made between analytically exact defined sine waves and disintegrated intrinsic functions as well as their specific influence on each other are determined.

Kinematics of extreme waves in deep water
TL;DR: In this article, the velocity profiles under crest of a total of 62 different steep wave events in deep water are measured in laboratory using particle image velocimetry, and the experimental velocities have been put on a nondimensional form in the following way: from the wave record (at a fixed point) the (local) trough-to-trough period, TTT and the maximal elevation above mean water level, hm of an individual steep wave event are identified.

Changes in the form of short gravity waves on long waves and tidal currents
TL;DR: In this article, the changes in wavelength and amplitude of the shorter wave train are rigorously calculated by taking into account the non-linear interactions between the two wave trains, and the results differ in some essentials from previous estimates by Unna.
Journal ArticleDOI
Stream function representation of nonlinear ocean waves
TL;DR: In this article, an analytical stream function expression representing a nonlinear gravity water wave is applied both to the representation of measured wave forms and also to nonlinear theoretical waves, where the stream function form is chosen so that it is a solution to the Laplace equation and the bottom boundary condition; the parameters are chosen by a numerical perturbation procedure that provides a best fit to the kinematic and dynamic free surface boundary conditions.

Steep gravity waves in water of arbitrary uniform depth
TL;DR: In this paper, the speed, momentum, energy and other integral properties are calculated accurately by means of series expansions in terms of a perturbation parameter whose range is known precisely and encompasses waves from the lowest to the highest possible.

On Modifications of the Zakharov Equation for Surface Gravity Waves.
Michael Stiassnie,Lev Shemer +1 more
TL;DR: In this paper, the Zakharov integral equation for surface gravity waves is modified to include higher-order (quintet) interactions, for water of constant (finite or infinite) depth.
Journal ArticleDOI
Phase velocity effects in tertiary wave interactions
TL;DR: In this article, it was shown that when two trains of waves in deep water interact, the phase velocity of each is modified by the presence of the other, and the change in phase velocity is of second order and is distinct from the increase predicted by Stokes for a single wave train.
