Describe processes represented by the model	This driver program solves the equations describing horizontal velocities in a buoyant, turbulent, plane jet issuing in a normal direction from a coast into a large volume of still fluid. Sedimentation under the jet is modelled using a hemipelagic rain formulation, bedload dumping, and downslope diffusion due to slides, slumps and turbidity currents.
Describe key physical parameters and equations	The equations are from Albertson et al. (1950) and Syvitski et al. (1988).
