|description3=Restricted to directional data. Only water cells that intersect with a defined discharge area start as that discharge area. An additional step is added to the watershed algorithm, where discharge areas are expanded to include neighboring unassigned water cells. Discharge area can also expand to water cells that are connected by culverts. After this step, some water cells can still be unassigned. Depending on the option [[Discharge remaining water (Watershed Overlay)|Discharge remaining water]], the remaining connected water cells are assigned to newly created discharge areas. | |description3=Restricted to directional data.
