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 | Calculated discharge areas are gradually expanded to unassigned cells. This expansion stops when the indicated fill distance is reached. Optionally this expansion also stops at road cells, depending on the configured option LIMIT_ROAD. |
|
DISCHARGE_REMAINING_WATER | bool | description=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 cell A flow 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 | ?. |
