Process description
| Processes represented by 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. |
| Key physical parameters & equations: | The equations are from Albertson et al. (1950) and Syvitski et al. (1988). |
