The Delineate Watershed step is used to delineate a watershed.
 
== Help ==
 
'''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.]]
