1. Non-erodible cell
* The hard bottom dataset value is set to the cell elevation.
2. Specified distance erodible cell
* The hard bottom dataset value is set to the cell elevation minus the specified distance associated with the polygon. For example, the cell has an elevation of -4.5 and the specified erodible distance is set to 1.0, the hard bottom value would be -5.5.
3. Specified depth erodible cell
* The hard bottom dataset value is set to the specified depth associated with the polygon. This value is interpreted as an elevation (Z).
 
 
All other cells not covered by a polygon as described above will be declared as fully-erodible.

CMS-Flow Hard Bottom Coverage

The CMS-Flow Hard Bottom Dataset tool generates a cell based dataset on a CMS-Flow grid that may be used as the hard bottom for a CMS-Flow simulation.

This tool is used with a CMS-Flow "Hard Bottom" coverage where the user can specify different types of polygons that are applied to the UGrid to create the hard bottom dataset. Guidance for setting up the Hard Bottom coverage can be found on the page, Hard Bottom Coverage.

CMS-Flow Hard Bottom Dataset Tool

Once there is a hard bottom coverage and all hard bottom polygons have been defined, the user can then run the CMS-Flow Hard Bottom Dataset Tool from the Toolbox.

Input Parameters

  • Target UGrid – The UGrid that is being used in the CMS-Flow simulation. This grid must have elevations defined at cells.
  • Input hard bottom coverage containing polygons – The hard bottom coverage.

Output Parameters

  • Hard bottom dataset name – Specify the name of the output dataset.
