Bottom pressure prequel (Water Overlay): Difference between revisions

Revision as of 11:36, 12 January 2024

Name	Prequel	Underlying data	Unit	Range	No data	Description
Bottom Pressure	BOTTOM_PRESSURE	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.

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.
This prequel can also have multiple input frames. In this case the values will be updated linear throughout the simulation period. For example 5 input frames over a 10 day simulation period result in a new value every two days.
Note: Input frames are not linked to the overlay's output timeframes.
