Unconfined Aquifers vs. Confined Aquifers
This is so helpful
I stumbled upon this whilst doing a hydrology quiz. And yes this video is 7 years old and probs not that appropriate.. But you have an attractive voice and could use that weapon to teach literally any topic for high school and college female students haha.
Wow this videos make the topics so easy to understand. thank you
Love this channel and its content!
@@erkanklc3144 thank you!
Thank you so much for explaining that . The 2d drawing really helped me understand everything much better .
Thank you!!!
Is recharge rate fixed or is it dependent on the draw down? I would think that with greater draw down youd have a steeper gradient in the cone which would lead to faster recharge. With a small draw the pressure difference isnt that great and it wouldnt draw as much water in.
I live in a cone of depression
@futurecanoe what are you doing here
Most useful and clear explanation on youtube.
Perfecto!
How about primary water? Confined?
When did mankind first realise that water was down there?
im in IIT, i have this topic in my course, thank u
Thanks, great explanation.
is there a way to calculate and estimate the level across the cone of depression?
Thank you very much. I could only understand it perfectly well after watching your video. But you didn't talk about the critical point...
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.
hi Sir, I am struggling to find a solution in my home, how can I reach you ?
So cool❤
thankkk youuuuuu
Thank you Mr! Hopefully I smash this hydrology/ hydrogeology x Biosphere exam now
Allah Ali yafakhr nassara
Thanks for the video
I am using this for a subject called "Materials in mechanical engineering" and my book that I was given sucks, you are a savior!
This is the concept
the best video ever !

❤❤❤❤❤❤
How did you come up with the 10 gpm?
Can an unconfined aquifer in a complicated topography of high and low altitude be modelled as a confined aquifer due to convergence issues?
dark magic for me, atleast it was. First year of Mechatronic and SOMEHOW I'm learning this. (p.s I live in Europe)
cool
thanks a lot
Thanks
Super❤❤
You think your smart dont you?
Reasonably smart I guess
Or increase gravity would blow up the top of confined unit
So to prevent sinkhole is by freeze the bottom and release when we need water and create sink hole
I would really appreciate an answer to this question: how can pressure head just be the distance of the water above the point? Would the volume of water pressing down on that point not also affect pressure? And the horizontal distance from one side of the container to the next? I am just super confused about the concept of water pressure, and would appreciate any resources you could direct me to.
Appreciated such clear and straightforward explanation. Many thanks!
Serious question Dane. The material bounded by both the solidus and liquidus, would you call it "mush" or "crystalline mush"?
ty hero
How can one can calculate sustainable aquifer yield or aquifer yield ?
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
Hahahha where In Somalia aboowe? Inshallah after i get my bachelors in Geology I can help with oil in rock and hit jackpot
Confined aquifer
You explain it well. How can I use vertical electrical sounding results to estimate hydraulic conductivity and transmissivity of an aquifer?
Your voice tone, a different vibe👄
Very clear explanation ever
Thank you so much, much respect You're way better than my uni professor, thanks a lot!
