Facets:
value: at that location
type: LOCATION
Source sentences:
text: However, if water level continues to decline to a point where the potentiometric surface drops below the top of the aquifer, then the aquifer will become unconfined at that location.
text: If the potentiometric surface of a confined aquifer declines to the top of the aquifer and the aquifer becomes unconfined, then the storage coefficient actually changes in the unconfined part of the aquifer.
text: If water levels decline below the top of a confined aquifer, the aquifer becomes unconfined (that is, the upper part of the aquifer becomes partially air filled) at that location and the fluid pressure becomes zero transferring all the stress to the aquifer matrix.
