Hello Dane can you please help me out. In the dupuit equation, does the radius of influence (call it r1) correlate to new height (y1) =initial height minus draw down? That is what I thought but the solution correlate y1 to the well radius. Which seems like an error. Your help would be greatly appreciated.
Im a bit confused on your question, but the Dupuit equation relates how much drawdown is produced in an observation well (y1) located some distance (r1) from the pumping well.
I have a question,I was born raised and still do and my family bought this property in the 40s and it got many criks on it that normally only ran when it would rain. There is one spring and concrete spring house my great uncle built. But my question is I built a home on a a piece of it 2 hills over and never had no springs on it till last March I found water flowin out and upon further investigation I now have 3 sweet little springs of water that flows more then enough water to where we completely unhooked from Patoka lake water that turned aweful to the best cold water I ever had and share to people when they need it. I wonder why after all them years it just now started showing? And instead of digging a well down through the ground I went in horizontal and 8 feet in or so it's opens up more and more daily. All I do is scoop out the silt sometimes. The Crick bottom I'll the way down to like a sandstone slate look and you could drive through it now no more rocks but that layer is about 10or15 feet below where we get the water. And some are even higher.the hole we use is about a foot and a half or 2with like a shale ceiling and sandstone bottom and gets lots wider as it goes back it's very pretty to look at I just don't get under it cause I have to shore some of the ground around it. I haven't measured the flow per gallon in a while but once couple months ago we measured it and and it was way less then now I'm sure of it so will the more it washes small rocks and silt out does that mean I'll keep getting more water? Thanks from French Lick In.
That’s interesting, I wonder if those springs will continue to flow. It may be that a nearby water well stopped pumping at some point and now you’re seeing the water table recover. Are you near any neighbors that have wells, or do you have one? It sounds like the springs are located at a geologic contact between two units- that’s typical for springs, that contact acts as a conduit for groundwater flow to the surface. Did you guys have a lot of precipitation in the year before the springs started flowing? I probably wouldn’t bet the farm on them flowing year round in the future if they just showed up recently. I would take flow measurements every month and record them and see what the flow is doing. If you want more help I’d be happy to help out, you can always email me at dane.m.andersen@gmail.com
