Model turbulent floods with the Smagorinski large eddy closure
A. J. Roberts, D. J. Georgiev, D. V. Strunin
Floods, tides and tsunamis are turbulent, yet conventional models are based upon depth averaging inviscid irrotational flow equations. We propose to change the base of such modelli…

Model dynamics on a multigrid across multiple length and time scales
A. J. Roberts
Most methods for modelling dynamics posit just two time scales: a fast and a slow scale. But many applications, including many in continuum mechanics, possess a wide variety of spa…

Initialization and the quasi-geostrophic slow manifold
S. M. Cox, A. J. Roberts
Atmospheric dynamics span a range of time-scales. The projection of measured data to a slow manifold, , removes fast gravity waves from the initial state for numerical si…
