Bottom pressure prequel (Water Overlay)

Name	Prequel	Underlying data	Unit	Range	No data	Description
Seepage p	SEEPAGE_P	Water Prequel		-1000000 to 1000000	Clamped to range	A grid of values containing the head of the ground water pressure caused by ground water in higher regions outside the project area.

Notes

• The unit is: Groundwater head of higher regions. (m + datum)
• The values in this prequel grid are clamped between -1000000.0 and 1000000. No data values are therefore not allowed.
