Prequels (Water Overlay)

Prequel overlays can be linked to the Water Overlay to initiate particular parts of the model with more accuracy and detail. They can even be used to link result types of one Water Overlay as prequel input to another.

Name	Underlying data	Description
Terrain elevation	Water Prequel	Datum of the terrain
Surface level	Water Prequel	Datum of the surface water level
Groundwater depth	Water Prequel	Depth of the watertable
Groundwater	Water Prequel	Datum of the watertable
Unsaturated fraction	Water Prequel	Fraction of maximum storage capacity the unsaturated zone which is filled with water.
