Surface Definition for Grids
The 2D adjustment layer alternative editor for grids is
used to create various data sets for the surface characteristics of grids. The
following columns are available:
| Column | Description |
|---|---|
| ID | Displays the unique identifier for each element in the alternative. |
| Label | Displays the label for each element in the alternative. |
| Grid Cell Size | Enter the desired width of each square-shaped grid cell. |
| Angle | Enter the desired rotation angle of the grid. |
| Manning’s n (Default) | Sets the default Manning’s n value for all computational grid cells not otherwise defined. |
| Infiltration Mode | Choose how to define surface infiltration over the computational grid. |
| SCS CN (Default) | Sets the default SCS CN value for all computational grid cells not otherwise defined. |
| Impermeability Fraction (Default) | Sets the default Impermeability Fraction value for all computational grid cells not otherwise defined. Uses only SCS CN when value is 0. |
