Ground water level area (Subsidence Overlay)

Ground water level areas are areas which can be used to define the initial ground water level, when detailed raster data of ground water depths is not available.

Icon	Key	Unit	Range	Description	Default value
	HI_GROUND_WATER_LEVEL	m + datum		The yearly high (average) ground water level in this area. Note that this is the ground water level (datum), not the ground water depth.	n/a
	LOW_GROUND_WATER_LEVEL	m + datum		The yearly low (average) ground water level in this area. Note that this is the ground water level (datum), not the ground water depth.	n/a

Notes

• Water level areas and subsidence areas can also be ground water level areas at the same time.
