Okay, I see where you are coming from, but if I may ask, is there a possibility that this website is more geared to the general public rather than people looking for more depth, possibly a depth that is reached by this event, and they are just simplifying it by implying the differences are irrelevant.

I am sure people do this, as I have seen many websites do it, I just wonder if that could be the case here.

Also, my source is not as good as I would hope, as it only says they are different, rather than showing why, so that is one of its pitfalls.

okay juuuust kidding I did some more research today and yes you're right, they're different. And I don't remember what you said the reason was but here it is:
Confined aquifers are just any aquifer that is trapped in between two layers of aquitards. However, an artesian aquifer has enough pressure that the water rises higher than usual in a well, forming a potentiometric surface, while in a normal confined aquifer the water level in a well tapped into it only rises to the top of the aquifer.
Thanks HannahD413!

That is what I thought, it had to do with pressure.

Thank you for clarifying and confirming.

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"?

Yes, well, sort of. In the case of unconfined aquifers, the potentiometic surface is the water table, in the picture, however, it is labeled incorrectly, it should be label potentiometic surface.

Where can I find a website that tells you how to interperate a topographic map :mrgreen:

Scroll down a bit and you'll get to a key for symbols and shading and stuff that can help you with interpretation.
