| Name | Prequel | Underlying data | Unit | Range | No data | Description |
|---|---|---|---|---|---|---|
| Min Unsaturated fraction | MIN_UNSATURATED_FRACTION | Water Prequel | 0 to 1 | Clamped to range | Used for initializing the minimal requested saturation of the unsaturated zone in the underground. |
Notes
- The values in this prequel grid are clamped between 0 and 1. No data values are not allowed, but negative values are interpreted as zero saturation.
- Note that this fraction is relative to the maximum water storage capacity of the terrain and not relative to the underground terrain volume. This amounts to the following formula:
Minimal requested amount of water in the unsaturated zone = relative ground water depth * WATER_STORAGE_PERCENTAGE * MIN_UNSATURATED_FRACTION.
