I think this shows it a bit more clearly, it is just that is is under the water table, however this picture shows it as a non-artesian aquifer. If this is something else, can someone clarify the potentiometric surface.
**EDIT: In this case, the water table and potentiometic surface are the same, although potentiometric surface would be more appropriate, because it is only in unconfined aquifers that they are truly synonyms.**[/quote]
I thought potentiometric surfaces only applied to confined aquifers. Once again I'm confused
Also what should we know about "stream gauging and monitoring"?
