This event hasnt been ran since like... at least 5 years ago lol that's why there aren't any practice tests out there.

and robotman09 please upload them ASAP. It would be greatly appreciated =]

Does anyone know of a good resource to learn about "Interpretation of fresh water features shown on USGS topographic maps". It's the first thing on the rules sheet so i figure it's pretty important...
Also the hydraulic radius in the Chezy equation is just the depth right?

THANK YOU!

Do you think there's anything else we need to know about that in general?

what would probably happen is that they give us a topo map of a certain area and ask us to identify certain freshwater features and where they're located or whatever. So learn how to use a topographic map if you don't already.

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
Let's see if this will work.

https://netfiles.uiuc.edu/valocchi/cee457/gw_geol.html The 1st image shows an artesian aquifer
Ok 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?

uh I'm pretty sure it's that all artesian wells are drilled into artesian aquifers, or aquifers that are trapped within two layers of impermeable bedrock. However, a flowing artesian well is located BELOW the potentiometric surface, so therefore the pressure of the artesian aquifer causes it to continue to flow freely. However, a non-flowing artesian well is just a regular well that taps into an artesian aquifer, not a normal aquifer.

what's the difference between a confined aquifer and an artesian aquifer? As far as I know, they're pretty much the same thing, but then why would they have different names?
edit: neeevermind got it =D
