http://www.tulane.edu/~sanelson/images/artesian.gifOk this is kind of late but in the picture it shows a "non-flowing artesian well" but I thought that the whole point of artesian wells was that they did flow and didn't need a pump. But if this is not true then what's the difference between a "non-flowing artesian well" and a regular well that has to be pumped?Let's see if this will work.Am I the only one who can't see the "image"? Can you put just the link to the picture because the description is kinda hard to understand without it. Thanks for trying either way

hmm actually, from what I understand, artesian aquifer and confined aquifer are synonymous. Someone please correct me if I'm wrong here. Not all wells drilled into an artesian aquifer can flow freely, such as non-flowing artesian wells. The free-flowing part is all about the location of the top of the well in relations to the potentiometric surface.From what I understand, it is sort of like squares and rectangles, where one is always the other but not vice versa. Artesian Aquifers are confined aquifers that contain water than can flow through a well without the need for pumping (an artesian well).
An artesian aquifer is a special type of confined aquifer, so maybe there are some confined aquifers that do not have enough water to cause the pressure that allows it to flow upward.
I know you said you figured it out, but this could be for anyone else who has the same question, also to make sure I am understanding it correctly.
I'm pretty sure it was this:You could be right, really, but I have seen it written as:
"A special kind of confined aquifer is an artesian system, shown below. Artesian systems are desirable because they result in free flowing artesian springs and artesian wells."
It is from a somewhat reliable source, Tulane University.
Could you post the source that says that they are synonymous?
I am with you on the free-flowing vs non-free-flowing wells, and there is a chance that this could be misleading, and I would hope to know so, in order to not use it in studying.
