A companion paper by Andreassen et M. (this issue) introduced and used a nonlinear, compressible, spectral collocation code to address the relative evolutions of two-dimensionM motions obtained in twoand three-dimensionM simulations of gravity wave breaking. That study illustrated the effects of instability on the wave field and mean flow evolution and suggested that two-dimensionM models are u...

Experiments on extremely steep deterministic waves generated in a large wave tank by focusing of a broadbanded wave train serve as a motivation for the theoretical analysis of the conditions leading to wave breaking. Particular attention is given to the crest of the steepest wave where both the horizontal velocity and the vertical acceleration attain their maxima. Analysis is carried out up to ...

Laser wakefield accelerators rely on the extremely high electric fields of nonlinear plasma waves to trap and accelerate electrons relativistic energies over short distances. When driven strongly enough, break, trapping a large population background that support their motion. Aside from limiting maximum field, this can lead accelerated electron bunches with energy spreads. Here, we introduce no...

In this paper, several numerical aspects of an existing model for fully nonlinear waves are improved and validated to study wave breaking due to shoaling over a gentle plane slope and wave breaking induced by a moving lateral boundary. The model is based on fully nonlinear potential flow theory and combines a higher-order Boundary Element Method (BEM) for solving Laplace’s equation at a given t...

Laboratory measurements of the fine space-time structure of short gravity-capillary waves, as well as Ku-band scattering at grazing and moderate incidence from spilling and plunging breaking waves in a wave channel are presented. Unsteady breaking waves are generated by focusing the waves in space and time. A scanning laser slope gauge was used for measuring short waves of wavelength 0.2-20cm, ...
