DISCHARGE_AREA | boolean by presence | Identifies the Area as a unique discharge area. | n/a |
Discharge areas represent regions where rain water ends up and potentially enters the water management system to be discharged.
Notes
- A discharge area always forms the basis of a watershed. Directional water flow, or the gradient of 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 initialization step of the watershed algorithm, water cells that are not yet assigned to any discharge area are automatically assigned to one when they are connected as a neighbor or by a culvert.
