Ground water (Water Overlay)

Attribute	Unit	Description
GROUND_WATER	nominal value	Whether water in the underground is simulated during the calculation. If this is deactivated, surface and underground infiltration, and underground evaporation do not occur. Water flowing in- and out of the sewer are still simulated when sewers are present.

Possible values

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

Notes

• Groundwater Overlays have the underground model active by default. The other Water Overlay variants have the underground model disabled by default.
