Groundwater level is calculated per cell.
- WHunderground = Wsat / WSP
- WLunderground = WHunderground + Hsurface - GBDM
Where:
- WLunderground = The groundwater level, relative to datum.
- 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 terrain 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.
