Karst hydrogeology

The unsaturated zone above the water table

Vadose means above the water table, in the unsaturated zone where the rock's openings hold both air and water and gravity pulls water downward toward the saturated zone below. Caves formed here, vadose passages, are cut by water flowing with a free surface, like an underground stream in air, so they tend to incise as narrow canyons and potholes rather than the rounded tubes of fully flooded phreatic development. Ford and Williams and White set the vadose zone against the phreatic zone in describing how caves develop. The referent is the unsaturated flow regime above the water table and the passages it shapes.[1][2]

Unit
The unsaturated zone above the water table and the passages cut within it
Recovery means
Not applicable
Measured by
Distinguished from the phreatic zone by free-surface flow features such as canyon incision and vadose entrenchment above the water table
