wow , u make it easy to understand. thank u
Do you teach courses please send the link if its possible.
Mam please continue to talk abt groundwater
Your explanation is short and nice..Please explain unit hydrograph..and drainage system in detail.. shivaji University from Maharashtra (india)
dum
which sensor is used
That is why buy drinking water and wash body better than taking shower soon draw too much water in large city like new York, LA, Houston, Chicago vv
Would you please send me more info about groundwater ?
Amazing video😀
Thanks
Could you please make a video on storativity and specific storage?
That's why small wells nearby a big well don't work because they're in the cone of depression created by the big well 🙂🤸♀
IDK AQ
Thanks you
Nice...
i like
Interesting - thanks
4 a long time i was thinking the water underground was in flat level now i know! thnks
I love it the video
THANKS
شكرا
Is there any way to find a confined aquifers? This will helps to find the points to dig the well. Can you explain the tools which helps to find confined aquifers?
Hi Vineesh, first we have to drill a well and see where we find water and when we start drilling through another layer of sediment or rock this area will produce no water. Sometimes when we are drilling we will get a big gush of water when we hit a confined aquifer because that water is under pressure. At this point we have to record how many feet we have drilled. Once we drill multiple wells we can compare where we found water and at what depth. After that we use modeling to give us an estimate or where confined aquifers are and how deep they are. As far as tools most drillers use a large drill tip that also shoots out water (or air) which breaks apart the bedrock and pushes any fragments to the surface. This is called a mud or air rotary drill. Hope this helps!

Wunderbar! Danke schön für die praktische Informationen
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!
Hi, great question! We actually made a video on this. Here is the link: kzread.info/dash/bejne/g56it7FpodSvpZs.html In an unconfined aquifer the draw down will look like a funnel but when we are pumping too much from a confined aquifer that has high water pressure we'll just see the water level in our well lower. If there is a large amount of pumping over a long period of time and the water pressure has been lowered we'd still get that same funnel shape of the water and also run the risk of running that well dry. This is why it's really important to know how much you're going to be pumping and if other household/municipalities are pumping from the same aquifer.
Watching from Philippines thank you for this video
Thank you
Crisp and precise info. Thanks
Thank you mam for your explanation
Can you make more videos please ..!!! I’m a civil engineering student And I want to know some more about Environmental Engineering!!
Great video
awesome
Is number one good choice to drill?
Hi Omer, good question. Any of these wells would be a fine location to drill. But the one thing to remember is if there is for example a chemical spill that gets into the groundwater, and it spilled in the area of land between wells 2 and 1, well 1 would be impacted sooner than well 2.
Ok
Nice information 👍
Thanks, Sachin!
Great video! It explains the issues and history and also gives some examples of how shoreline homeowners can have a positive impact on their lake. It would be great if U of M could put links to the resources mentioned at the end of this video in the description area.
