Ground water (Water Overlay)
|GROUND_WATER||nominal value||Whether and how water in the underground is simulated during the calculation.||Infiltration Only|
|0.||None: No infiltration, no groundwater flow, no underground evaporation.|
|1.||Complete: Full groundwater simulation, including infiltration, flow, and evaporation|
|2.||Infiltration only: Water can Infiltrate into the unsaturated zone only, but no further underground flow or underground evaporation is simulated. The unsaturated zone is simulated to have infinite capacity.|
- Groundwater Overlays have the underground model active by default. The other Water Overlay variants have the underground model set to infiltration only. This is a recommended setting, trading in an imperceptable amount of accuracy for a more performant calculation setup.
- This setting does not affect water flowing in- and out of the sewer.
