The Watershed Overlay's model calculations depend on a number of calculation-wide parameters. These parameters are available as attributes of the watershed overlay and can be modified as such.
| Icon | Attribute | Unit | Description |
|---|---|---|---|
|
FILL_DISTANCE | m | Discharge areas expand to unassigned cells until the fill distance is reached or, if LIMIT_ROAD is enabled, a road cell is encountered. |
|
DISCHARGE_REMAINING_WATER | bool | Create additional discharge areas for water terrains that are not connected by culverts to the general water system. Only water terrains that are larger then the configured minimal area can become independant discharge areas. |
|
CULVERT_FLOW_DIRECTION | bool | Use culvert flow direction to limit the way discharge areas are propagated. When active and water flows from cell A to cell B through a culvert, the discharge area of B is propagated to cell A when it is not yet assigned to a prioritized discharge area. |
|
MIN_AREA | m2 | A minimal area size threshold for water terrains in order to be taken into account as an independent discharge areas. |
|
LIMIT_ROAD | bool | Whether the gradual expansion of calculated watershed to unassigned cells should stop at roads. |
