Notes
- A discharge area always forms the basis of a watershed. Directional water flow (or the steepness in the terrain) 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.
