Parameter-free higher-order Schrodinger systems with weak dissipation and forcing
Jack Keeler, Alberto Alberello, Ben Humphries +1
The higher-order nonlinear Schrodinger equation (Dysthe's equation in the context of water-waves) models the time evolution of the slowly modulated amplitude of a wave-packet in di…

On the stability of fully nonlinear hydraulic-fall solutions to the forced water-wave problem
Jack S. Keeler, Mark G. Blyth
Two-dimensional free-surface flow over localised topography is examined with the emphasis on the stability of hydraulic-fall solutions. A Gaussian topography profile is assumed wit…

Exact solutions for submerged von Kármán point vortex streets cotravelling with a wave on a linear shear current
Jack Keeler, Darren Crowdy
New exact solutions are presented to the problem of steadily-travelling water waves with vorticity wherein a submerged von Kármán point vortex street cotravels with a wave on a lin…
