Overview

Models being tested use a variety of hydrodynamic approaches together with variations in treatment of bottom or slide motion. 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. Nonlinear Shallow Water Equations (depth-integrated, hydrostatic)
  2. Boussinesq or depth-integrated non-hydrostatic equations
  3. 3D non-hydrostatic models (sigma-coordinate, terrain following, sparse vertical resolution)
  4. Navier-Stokes solvers

Treatment of slides

  1. Solid slide, or prescribed impermeable bottom motion
  2. Viscous fluid slide
  3. Granular or debris flow slide
  4. Multiphase - slide treated as mixture or distinct phase in variable density model
