* The result displayed is in terms of water height. In the underground, water in the unsaturated zone is assumed to be equally spread across the entire height of the unsaturated zone. The displayed result is the height of the water column if the water from the unsaturated zone were to be placed on the surface.  
* The displayed result is the height of the water column below the surface. It is the sum of the amount water in the saturated zone and the unsaturated zone, where the amount is represented as the water column. This value can be used to validate water balances and comparisons with values such as water on surface, rain, seepage and evaporation.
* In the underground, water in the unsaturated zone is assumed to be equally spread across the entire height of the unsaturated zone.  
* To obtain the amount of water in the saturated zone, the Water datum height is converted using the surface datum height, the underground depth and the water storage percentage.

 GROUND_LAST_STORAGE m (mm)¹ Last The (effective) amount of water in both the underground unsaturated and saturated zone.

¹ the units between () are as displayed in the 3D client. If exported to GeoTiff the SI-convention is used: meters (m) and seconds (s).

Notes

  • The displayed result is the height of the water column below the surface. It is the sum of the amount water in the saturated zone and the unsaturated zone, where the amount is represented as the water column. This value can be used to validate water balances and comparisons with values such as water on surface, rain, seepage and evaporation.
  • In the underground, water in the unsaturated zone is assumed to be equally spread across the entire height of the unsaturated zone.
  • To obtain the amount of water in the saturated zone, the Water datum height is converted using the surface datum height, the underground depth and the water storage percentage.
