Experimental velocities and accelerations in very steep wave events in deep water
John Grue,Atle Jensen +1 more
TL;DR: In this article, the entire experimental velocity and acceleration fields in the six steepest cases of a campaign of totally 122 large wave events in deep water are documented, where totally 36000 experimental velocity vectors are put on non-dimensional form using a suitable reference velocity defined by ϵg/k, where k and ϵ are obtained as follows: from the wave record at a fixed position the local trough-to-trough period, TTT and the maximal elevation of the event above mean sea level, ζm are defined.

A modified nonlinear Schrödinger equation for broader bandwidth gravity waves on deep water
TL;DR: In this article, the modified nonlinear Schrodinger equation of Dysthe is extended by relaxing the narrow bandwidth constraint to make it more suitable for application to a realistic ocean wave spectrum.
Method for Calculating Forces Produced by Irregular Waves
TL;DR: In this article, a new method is described and evaluated for calculating wave forces on offshore structures based on an extension of Airy theory for two-dimensional waves and uses a linear filtering technique to calculate wave forces as a function of time for wave profiles of arbitrary shape and length.

U. Brinch-Nielsen,I.G. Jonsson +1 more
TL;DR: In this article, the authors derived fourth order evolution equations for three-dimensional Stokes waves on arbitrary water depth and demonstrated that dimensionless water depth as well as wave steepness influences the applicability of the deep water stability expressions.
