There are a few modes available for the [[Water Module]], dictating how to handle groundwater:
{{nominal list|zeroindex=true
* '''None'''. No [[infiltration model (Water Overlay)|infiltration]], no groundwater flow, no [[evaporation model (Water Overlay)|underground evaporation]].
||None: No [[infiltration model (Water Overlay)|infiltration]], no groundwater flow, no [[evaporation model (Water Overlay)|underground evaporation]].
* '''Complete''' Full groundwater simulation, including [[infiltration model (Water Overlay)|infiltration]], flow, and [[evaporation model (Water Overlay)|evaporation]]
||Complete: Full groundwater simulation, including [[infiltration model (Water Overlay)|infiltration]], flow, and [[evaporation model (Water Overlay)|evaporation]]
* '''Infiltration only''' Water can [[infiltration model (Water Overlay)|Infiltrate]] into the unsaturated zone only, but no further underground flow or [[evaporation model (Water Overlay)|underground evaporation]] is simulated. The unsaturated zone is simulated to have infinite capacity.

Icon Attribute Unit Range Description Default value
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.

Notes

  • 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.
