The variability of the large-amplitude internal wave field on the Australian North West Shelf
Internal waves Solitary waves Internal tide Continental slope Australian North West Shelf (14–221S, 114–1261E)
2015/6/30
Observations are presented of large-amplitude internal waves (LAIWs) generated by the steepening of the internal tide on the Australian North West Shelf (NWS) over a 4-month period extending from stro...
Patch behaviour and predictability properties of modelled finite-amplitude sand ridges on the inner shelf
Patch behaviour predictability properties modelled finite-amplitude sand ridges inner shelf
2009/11/2
The long-term evolution of shoreface-connected sand ridges is investigated with a nonlinear spectral model which governs the dynamics of waves, currents, sediment transport and the bed level on the in...
A simple nonlinear model of the generation of Kelvin waves is presented and applied to internal Kelvin waves in Lake Michigan. It is shown that a Kelvin wave which has a wavelength longer than the Ros...
