Groundwater level is calculated per cell.

Where:

  • = The groundwater level, relative to datum. Also known as the watertable.
  • = The height (column) of the saturated zone.
  • = 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.
  • = The surface height in the cell, relative to datum.
  • = The GROUND_BOTTOM_DISTANCE_M (effectively available height in the underground model).
  • = The WATER_STORAGE_PERCENTAGE of the underground terrain type, used here as a fraction.
