The RMA2 Nodal Transition (Marsh Porosity) dialog is used to define the RD Card: Automatic Roughness Coefficient Assignment by Depth. See the section "Wetting and Drying", "Elemental Elimination", "Marsh Porosity", and DA and DM Card descriptions in the RMA2 model documentation for more information. The following parameters can be set in the Nodal Transition (Marsh Porosity) dialog:

  • Minimum Land Elevation
    • Distance below each node's bathymetry value
    • Constant elevation, independent of nodal bathymetry
  • Transition range of distribution
  • Minimum wetted surface area factor
