Groundwater level is calculated per cell.

WHunderground = Wsat / WSP
WLunderground = WHunderground + Hsurface - GBDM

Where:

  • WLunderground = The groundwater level, relative to datum. Also known as the watertable.
  • WHunderground = The height (column) of the saturated zone.
  • Wsat = The amount of water in the saturated zone. The height of the water column if the equivalent amount of water was placed on the surface.
  • Hsurface = The surface height in the cell, relative to datum.
  • GBDM = The GROUND_BOTTOM_DISTANCE_M (effectively available height in the underground model).
  • WSP = The WATER_STORAGE_PERCENTAGE of the underground terrain type.
