Ground water (Water Overlay)

Attribute	Unit	Description
GROUND_WATER	nominal value	Whether and how water in the underground is simulated during the calculation.

Possible values

• 0: No infiltration, no groundwater flow, no underground evaporation.
• 1: Full groundwater simulation, including infiltration, flow, and evaporation
• 2: Infiltration only, but no underground flow or underground evaporation.

Notes

• Groundwater Overlays have the underground model active by default. The other Water Overlay variants have the underground model set to infiltration only.
• This setting does not affect water flowing in- and out of the sewer.
