Groundwater level is calculated per cell.


= 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 WATER_STORAGE_PERCENTAGE of the ground terrain type, used here as a fraction.
= The groundwater level, relative to datum. Also known as the watertable.
= the datum height of the surface of cell c, set by the elevation or a Terrain elevation prequel.
= The ground bottom distance of the cell c, defined by a Bottom distance prequel or a general GROUND_BOTTOM_DISTANCE_M of the Water Overlay.
