Models being tested use a variety of hydrodynamic approaches together with variations in treatment of suspended and bedload sediment transport. Models are can be thought of as being categorized across both variables, and are thus indicated below by two category numbers. Models are grouped according to

Hydrodynamic approach

  1. Depth-integrated 2D models (hydrostatic or weakly dispersive)
  2. 3D models (hydrostatic or non-hydrostatic)

Treatment of sediment transport

  1. Bedload transport retained or neglected
  2. Turbulent diffusion of suspended sediment retained or neglected

The set of models being tested includes:
