Discharge area (Watershed Overlay): Difference between revisions

Revision as of 11:23, 10 June 2020

A discharge area always forms the basis of a watershed. Directional water flow, or the steepness in the terrain depending on the discharge method, is backtracked to determine the watershed for a particular discharge area.
When multiple areas overlap for a particular grid cell, only the first encountered discharge area is used.
In the first step of the watershed algorithm, connected water cells that water cells will be assigned to this discharge area when they are not yet assigned to any discharge area.
