| UNSATURATED_FRACTION | fraction | The initial fraction of the maximum storage capacity of the unsaturated zone which is filled with water. | 0 |
Notes
- The maximum storage capacity of underground terrains can be configured with the Water storage percentage attribute.
- 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: Amount of water in the unsaturated zone = ground volume * WATER_STORAGE_PERCENTAGE * UNSATURATED_FRACTION.
- For example, an underground terrain with a water storage of 25% and a ground water depth of 1 m and a configured unsaturated fraction of 0.25 will result in 0.0625 meter water in the unsaturated zone. (25% of 25% of the total volume of 1 m3)
