TL;DR: In this article, an exact breather solution of the one-dimensional focusing nonlinear Schrodinger equation with nonzero boundary conditions was shown to emerge locally, as an asymptotic structure arising from the propagation of an arbitrary large decaying pulse.

TL;DR: In this paper, the authors studied the transformation of surface envelope solitons traveling over a bottom step in water of a finite depth and derived the parameters of transmitted pulses and subsequent evolution of the pulses in the course of propagation.

TL;DR: Gouin et al. as discussed by the authors developed a highly nonlinear model for wave propagation over a variable bathymetry with HOS method, and presented a validation case to assess accuracy and efficiency of both approaches which are compared.

TL;DR: In this article, the evolution of nonlinear deep-water surface gravity waves with the envelope in the form of a large-scale rectangular barrier is investigated in a long tank, where the authors show that for a range of initial parameters, the nonlinear wave packet is not disintegrated by the Benjamin-Feir instability but exhibits a specific, strongly nonlinear modulation, which propagates from the edges of the wavepacket towards the center with finite speed.
