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 water depth * 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)
