Ground water (Water Overlay)
| Icon | Attribute | Unit | Range | Description | Default value |
|---|---|---|---|---|---|
| GROUND_WATER | nominal value | Whether and how water in the ground is simulated during the calculation. | Infiltration Only |
| 0. | None: No infiltration, no groundwater flow, no ground 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 ground flow or ground evaporation is simulated. The unsaturated zone is simulated to have infinite capacity. |
Notes
- Groundwater Overlays have the ground model active by default. The other Water Overlay variants have the ground model set to infiltration only. This is a recommended setting, trading in an imperceptible amount of accuracy for a more performant calculation setup.
- This setting does not affect water flowing in- and out of the sewer.
