Well explained, I'm from northern Somalia where water well is extremely valued, we have a lots of valleys in the area where i am from, so hopefully with the help of your explanation i will hit the jackpot. Thank you
Very clear explanation..thank you! Was watching a farming documentary and had to stop it to quickly refresh my understanding of acquifers. You offer such an efficient explanation I was able to waste no time in jumping back into the documentary and continuing to learn about farming! Thanks 😊
It means to say find the opening of Aquifers to pull water efficiently and utilize in a Moderate Way. And, make use of Water Conservation projects to recharge Aquifers.
Not sure if you will see this but we have a carbon capture sequestration planned for the confined Mahomet Aquifer here in illinois. Wouldn't storing co2 under an aquifer potentially cause harm to the water source??
My community has started using well water as our primary water source but the well heads aren’t rejuvenating as fast. I’m here to try figure out what else I can do
Fine work! Unfortunately my professor does not have the organization and structure this video has. He drew a graph that made little sense and had no legend. I was just looking at a bunch of dots and lines with no explanation.
How does one obtain a potentiometric/pressure reading in the water well of a confined aquifer? Does one remove the well head cap each year to see if the water level has dropped and/or risen with a string measurement or ruler? I imagine one must use professional service to ensure confined aquifer is not contaminated by doing so, either.
Yes, you can remove the well cap and use a water level tape. Usually the well will have a smaller pipe to insert the water level tape to take a measurement, that way you don't get the tape wrapped around the pump column or cables. The water level tapes are quite expensive, but you can rent them from environmental supply shops. You don't need a professional to do this, just the right equipment and decontamination procedures. Don't go sticking a contaminated tape into your well!
Good day! Tell me please, is there any information on the distribution of the depression cone in the confined aquifer? For some reason, they always depict a funnel passing through a waterproof layer. How can it spread evenly through the clay layer? It seems to me that the depression funnel in the confined horizon should be enclosed between the impermeable layers, or am I wrong? Thanks!
The monitoring wells will be installed in the permeable layers, not the clays or impermeable layers. So when you see that "funnel" or "cone", it is representing the head in the permeable layers, not the head in the clay or impermeable layers. So when you see the cone spreading through the clay layers, that just means the head in the permeable layers rises to an elevation that is the same as the impermeable layers - it does not represent head in the impermeable layers. Hope that makes sense!
@@daneandersen8181 Thanks for your reply! however, it is still unclear what a sinkhole will actually look like when pumping water from an aquifer enclosed between two impermeable layers (eg, clay). If the static water level in the well is set above the roof of the watertight layer (in the pressure well), then the water level will decrease during water intake (the static level will drop to the dynamic water level). In this case, the depression funnel, it seems to me, should not go beyond the aquifer, enclosed between the layers of clay. Or is it not so?
No, not necessarily. You could have confined conditions in a shallow aquifer, and unconfined conditions in a deeper aquifer. What really makes the difference is if the water in that aquifer is under pressure because a low permeability rock unit (e.g. clay or shale) is overlying the aquifer
@@daneandersen8181 if i dig hole up to confined aquifers and put pipe let say 60meters deep, isnt hard to pump out water using manual piston water pump?
I have a dug well and the water table is about 17 feet down and I have a water pipe at the bottom of a hill that is higher and never stops flowing. is the pipe in the side of the hill an confined aquifer and is it cleaner water ?
Hi i saw all your videos and i want say perfect....... I wanna ask for a pumping test for permeability why using piezometer and observation well rather than just observation well
A piezometer is basically an observation well. Piezometers are just small diameter wells that are mainly used for measuring water levels (the small diameter makes it cheaper to install, but you sacrifice the ability to insert a large pump into it). The main point is that during an aquifer test, you measure water levels in the well you are pumping, and any surrounding wells (which in that sense are observation wells, and could be a regular well or piezometer)
what is the thickness of unconfined aquifer ? and thickness of confined bed? or the distance between unconfined aquifer and confined aquifer? and the thickness of confined aquifer?
good job my question is can we recharge unconfined aquifer with Rooftop water in rainfall season directly through injecting method of PVC pipe upto 200 ft

gotta be one of my favorite aquifer videos on youtube
Most useful and clear explanation on youtube.
Great video mate, easy to follow and greatly explained! Earned a subscriber.
Basic enough for me to understand lol thank you
way better explained then my lecture teacher
very powerful information this will force me to have my well deepen again to collect more water
Great video! Although, i am currious. Are confined aquafers always underneath unconfined or not?
Helping me for my test,VERY helpful!
Thank you Mr Anderson
Plss keep posting more videos..
Very thorough and helpful explanation. So what then is a semi-confined aquifer?
It means to say find the opening of Aquifers to pull water efficiently and utilize in a Moderate Way. And, make use of Water Conservation projects to recharge Aquifers.
Not sure if you will see this but we have a carbon capture sequestration planned for the confined Mahomet Aquifer here in illinois. Wouldn't storing co2 under an aquifer potentially cause harm to the water source??
Very clear explanation ever
Informative.
Why would the water not rise in a confined aquifer Well to the same elevation as the head of water to the left of your diagram.
Can an unconfined aquifer in a complicated topography of high and low altitude be modelled as a confined aquifer due to convergence issues?
Thanks, you made this so easy to understand
Nice video! Very well explained! Got it! 👌👍🤗👏😀😉
there is one more well --> artesian well can u explain artesian well to?
What will be the average depth where you can find the confined acquifer?
My community has started using well water as our primary water source but the well heads aren’t rejuvenating as fast. I’m here to try figure out what else I can do

When did mankind first realise that water was down there?
Which will give more water confined aquifer or unconfined aquifer
hi Sir, I am struggling to find a solution in my home, how can I reach you ?

Thanks, great explanation.
So if we insert a peizometer in an unconfined aquifer, will the water rise above water table?
Nope! the water level in your piezometer will be the same as the water table in the unconfined aquifer
Bro great video!
How about primary water?
Confined?
So to prevent sinkhole is by freeze the bottom and release when we need water and create sink hole
Thank you.. Can I use this for teaching?
Sure!
Sir,
How to find underground confined Aquifers ?
So basically unconfined also means shallow well and confined be a deep water artisiean well?
No, not necessarily. You could have confined conditions in a shallow aquifer, and unconfined conditions in a deeper aquifer. What really makes the difference is if the water in that aquifer is under pressure because a low permeability rock unit (e.g. clay or shale) is overlying the aquifer
@@daneandersen8181 Knowledge is held, you don't know until you ask... Appreciate it, m8
Thank you Mr! Hopefully I smash this hydrology/ hydrogeology x Biosphere exam now
so unconfined and confined aquifers can be in the same location, right?
Yes, they will just be located at different depths.
@@daneandersen8181 if i dig hole up to confined aquifers and put pipe let say 60meters deep, isnt hard to pump out water using manual piston water pump?
What is a differences between Water table and water level sir
Great video
I have a dug well and the water table is about 17 feet down and I have a water pipe at the bottom of a hill that is higher and never stops flowing. is the pipe in the side of the hill an confined aquifer and is it cleaner water ?
Possibly, how far apart are the well and the hill?
Great video keep it up

Can I contact with you doctor
Thanks
what is a perched aquifer?
Tejas Patil a perched aquifer is a relatively small aquifer above a larger regional aquifer.
This is the concept
Our Aquifer is not keeping up with demands here in Honolulu - need massive desalination Plant wiki wiki!
Great!
Amazing explanation sir... Thank you
what is the thickness of unconfined aquifer ? and thickness of confined bed? or the distance between unconfined aquifer and confined aquifer? and the thickness of confined aquifer?
Sir thank you
Awesome
Thanks:)
Good job
good job
my question is can we recharge unconfined aquifer with Rooftop water in rainfall season directly through injecting method
of PVC pipe upto 200 ft
Or increase gravity would blow up the top of confined unit
sir pz begali vartion
THANK YOUUUU!!!
Hi
Confined aquifer
The only reason I want to learn this is because my exam is gonna have this on it and I didn't even know we learned it lmao
this dude sounds like Jim from the office
That's a new one but I'll take it as a compliment!
Bill O'Reilly approved! Okay.
Good information well done. Alright. Hope you get this Okay.
See South Parks Bill O'Reilly ok.
