Where is the Water Table?
Вставка

- This video defines what we mean by the term water table. We go into the field to demonstrate how to measure the depth to groundwater in two wells. We use this information to determine the position of the local water table and the direction of groundwater flow. Finally, we discuss how the depth to the water table may vary and direct viewers to a US Geological Survey website where they can explore groundwater data from nearby wells in their state.

Great video, really helped me understand what the water table actually is for my intro to construction module. I could do the calculations but this has really helped me visualize what it actually is and better understand it, thanks!
Excellent video! This video helped me understand what water table is in a way that i will never forget. Keep up the great work.
Only video that actually helped me understand water table..thank you 😀
Correct. I was a second generation water well driller using a cable tool rig. That method is slow, but if you're paying attention you'll learn more.
This has helped me tremendously. Thank you!
Awesome and educational video, it had helped me a lot
great video! I really like your channel and hope the best for it keep it up :)
Great info. Many thanks 🥰...
Wonderful video.
Thank for this info,but i have question ,adrilling ground water has 345m and it has ignibrite and bazalt formation so how to calculate well logging of blind casing and screen casing after finishing?
Great educational video here, very understandable and logical. a bit old fashioned, but that 90s nostalgia is OK with me :P
What is the best way to raise the water table?
ahhh it helps me a lot!
S.A.E vs Metric: in the 80's the USA was going to switch to metric, and had actually started the conversion but then determined that both systems were required mainly in the area of machining, screw hole size and threads were the points of determination and the torque they had and neither of the two systems could do both so they adopted both measuring units and the world is a better place with them both as science uses the metric system
In Canada, we use pounds in fruit & vegetable section in retail stores just to make pricing look lower. Search me why the adopted metric system is still not on top of the pound system in 2024. At times you just gotta let go, lol
Grreat video
So it seems that I need to find a place where I want to build my house that has a water table that’s very high but in reference to the dry months the dryers periods of that area with the water table that’s closest to the land surface I’ll dig my well all the way down to the water table graft at the dryers. Of the year for that specific area and that should give me a reliable source of water of course the water well it’s not gonna be my only source of water but this video was very helpful
When measuring the water level, are you measuring from the land surface or the top of the well?
I believe land surface
thank you....
Too nice 👍
GREAT!!!!!!!
great lessen
Thank you
Nice video..I can
thanks
Without a previous predug well, we're back to guessing where the water level is at.
Your local geological service may be able to provide information.
Actually, I learned that I need to dig a well on my land. I did so, and use a 2 inch PVC pipe instead of a 4 inch like in the video. I am paranoid about my cell phone or thermometer falling into the pipe. I will spend a year studying the variation in the water table, and then make a decision on geothermal.
Excellent video production work. Please help me do the same for "What is Metallurgy?"... I can work with you.
if you were to take a pipe, lets say 50m hose, put one end in a well and the other in a stream, if a siphon is created will water flow from the well to stream
Yes as long as the highest point of water in the well is above the end of the tube
When you're digging, how do you know when you hit the water table?
are u f*ckin kiddin?
Fun with flags is great.
In California central valley fruit basket of the world we are in a servicer drought for over six years with no mountain snow fall in the Yosemite Valley area. During the 1920s and 30s and 40 years you would be able to drill down 30 ft in reach water in the Fresno area outlining City's, also in the Tulare area and the outlining city's and town's. The river systems and the lake systems in this area are no more because of the canals. The natural rate of water flow has been interrupted by mankind destroying the landscape by planting fruit trees and vegetables, hint bread basket of the world no more.
Voters in California (and elsewhere) continue to elect idiots to rule over them. Why can we not live with nature instead of trying to make it conform to what we want it to be. The Everglades in Florida has also been destroyed by people trying to reshape it. There are these type of issues all over the globe.
If they had dug an actual hole it would have illustrated it better. There's no way to tell how deep the hole is. It just looks like a water fountain.
what if the 2 wells are no closer than 1/2 mile apart with hills between. all these videos are useless. only way is to dig.
the wells in my are vary from 900 to 50 feet deep.with in a half mile circle the wells vary from hand dug to 900 feet drilled. thats a 50 foot well in between a pair of wells 800 to 900 feet deep. one well 50 foot with in 60 feet of another well 400 foot. go figure. water is where you find it.8 wells drilled on my place varied from 300 to 500 feet deep by different drillers with no water.
And that's how scp 2770 escape the desert
Your findings are dependent on both wells having the exact same amount of well casing above ground level which is highly unlikely. Measurements should in fact have been taken from ground surface, not top of well casing. Your findings dont seem to take into account hydrostatic pressure. I believe your findings are misleading....but interesting perspective.
hmmm...should have been the height above a stable reference (sea level).
its obvious how much to subtract from his reading...duh
commenter must be a millenial
Go Pack! 1:44
The man is reading from a text . Need to slow down.
Don’t lie you got this from the oversimplified scp 2770 comic
🤨🤨🙄🙄🤕🤕🤯🤯😤
You must love Jehovah your God with all your heart and with all your soul and with all your mind and with all your strength. You must love your neighbor as yourself. Jesus the anointed is Lord! Repent and be baptized and believe the Gospel.
thumbs down! In the beginning of the video, your ground water measurements are in meters. Later on you talk of ground water depths in feet! Certainly you can do better.
dumbass certainly u can convert ... hint: 1m=3ft millenial moron
This is America, we don't use meters.
Neither do we; we use metres.
wait wait wait wait, I dont think you know that the majority of people AREN'T AMERICAN!!! most people in the world use the metric system
@@victormaurer5316 Americans don't care about the rest of the world but we are a patient people, we will wait until you come around to our way of thinking. 🤣
Why do all these people think the have to use the stupid metric measurements instead of S.A.E, which makes much more sense.
how does metric not make sense??? how the hell do you even REMEMBER your system?
miles (1760 yards)
yards (3 feet)
feet (12 inches)
INSTEAD OF:
kilometers (1000 meters)
meters (100 centimeters)
centimeters (10 millimeters)
Thank you
