| '''Stream threshold value''' – This value is used to modify the stream density. Lower values will cause the streams to be more dense while higher values will create fewer streams in the completed model.
| |
| | |
| '''Apply to Display''' – Select this button to apply the stream threshold value entered to the display.
| |
| | |
| '''Create Tc Coverage''' – If this toggle is selected, a Time Computation coverage containing an arc with the longest flow path is created after delineating the watershed and sub-basins.
| |
| | |
| '''Units''' – This button is used to define the model and computation coordinates and units. A user can turn on the option to create a Tc coverage and change which data is computed by selecting the ''Drain Data Compute Opts...'' button in the Units dialog.
| |
| | |
| '''Sub-divide Watershed''' – This button subdivides the watershed into sub-basins based on the maximum sub-basin area entered.
| |
| | |
| '''Delineate Watershed''' – This button delineates the watershed and computes each sub-basin's data based on the selected watershed delineation parameters.

| After delineating a watershed, it is possible to [[WMS:DEM Basins|manually edit the extents of the watershed.]]
