Unsaturated fraction prequel (Water Overlay)

Name	Prequel	Description
Unsaturated fraction prequel	UNSATURATED_FRACTION	Used for initializing the saturation of the unsaturated zone in the underground.

Notes

• The values in this prequel grid are clamped between 0 and 1. No data values are not allowed, but negative values are interpreted as zero saturation.
