Ground bottom distance m (Water Overlay)

The ground bottom distance m setting can be configured in the Simulation Settings step of a Water Overlay wizard when the Ground water mode is set to Complete.

Icon	Attribute	Unit	Range	Description	Default value
	GROUND_BOTTOM_DISTANCE_M	m	0 to 10000	Assumed distance under the surface terrain where the bottom boundary is situated.	10

The groundwater level cannot go below this depth, relative to the surface. The maximum amount of water that can be stored underground is equal to this attribute multiplied by the local terrain's WATER_STORAGE_PERCENTAGE.

Ground bottom distance.

Notes

• A varying ground bottom distance can be configured when using a Bottom distance prequel.
