RMA2 Nodal Transition (Marsh Porosity) dialog
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. This dialog is reached through the Global Methods tab of the RMA2 Model Control dialog.
The following parameters can be set in the Nodal Transition (Marsh Porosity) dialog:
- Minimum Land Elevation – This section allows one the following values to be set:
- Distance below each node's bathymetry value
- Constant elevation, independent of nodal bathymetry
- Other Parameters – The follow values can be set:
- Transition range of distribution – Default is 2.0.
- Minimum wetted surface area factor – Default is 0.02.
