It should make you feel better that you’ll probably not die from it, your car probably has lots of safety features that’ll prevent death in this case, including your airbags. I’d only be concerned if you live in a place where your roads are traveled very very rarely, and even then usually someone’ll notice a sinkhole before you’d run out of water down there

just some of my thoughts so take them with a grain of salt 1. take probes of the soil and excavate and change it if necesarry(very expensive so most likely not often used, if ever) 2. controll the waterflow in the soil better, maybe with some blockades or a waterproof layer, so it cant reach deeper then the engineers want to

@@MrTwinkieeater Sounds like it may be a cover collapse type sinkhole and may have sealed itself when it collapsed. When to roof of a void or cavern collapses, it can naturally drop the soils from above and like a funnel effect seals itself with the surface soils and materials. You can place stakes on 4 sides at the top and run string tight across to each stake and take periodic measurements in the middle to see if it still shows signs of subsidence. Sounds like you don't have much to worry about since it holds water for long periods of time.

The drainage erosion holes under an asphalt road can be so big that they get measured in DDBs (Double Decker Buses). I came across a 0.5 DDB hole in Scotland a few years ago and rang the highways department engineer to report it. I gave location and suggested that they quickly measure the volume, then order concrete and fill it up before the road collapses. Next time I passed, what had been a huge hole was just concrete.

When I was a kid the water pipe coming into our house sprung a leak. They sent someone out to look at it and determined it was on their side of the valve, and decided since it was late Friday and the flow wasn't too bad that they would save some overtime by fixing it Monday. My brother and I played in the water and sand all weekend and had a grand old time! (My back got sunburnt!) Anyway, Monday rolled around and they showed up with a backhoe, which promptly had one of its tires break through and collapse part of the road. By the time they got it out the hole was probably 6 feet across, right in the middle of the road. I suspect they failed on the cost benefit analysis portion overall. I make a point, anytime I see water coming out of somewhere it shouldn't, to make sure whoever is in charge knows about it. The people usually are pretty dismissive, so I tell them that story to give them an idea of what can happen if they don't deal with it quickly.

You should do a scale model of irrigation pivot pumps effect on surface and ground water. Saw a demonstration on it 10 years ago. It was fascinating how powerful these pumps are

This was taught wonderfully. Thank you!

oh. that's why there is "dirty" water and holes infront of my condo and day later a huge hole and there's a big pipe under it. and the pipe was broken

Sink holes are my biggest irrational fear. Seriously afraid I will fall asleep and wake up at the bottom of one or not wake up at all because the ground swallowed me.

Same. That fear worsened for me when a sinkhole opened up only one block away from my house and it destroyed an intersection in the road and it took 2 weeks to fix it.

Nick Lemke I'd like to say you are crazy but my niece had one open up in her front yard while playing and she almost died or would of been seriously hurt but managed to catch herself lol they did a news story on it so I guess it's not really that irrational lol

sean strickland what makes it irration for me is I live in Oklahoma where the ground is clay so sink holes don't really happen here.

Except for that split second of "oh shit im falling!" Or in the case of the man in florida long enough to cry for help but die before it gets there.

分かりやすい！

Near where I live, sinkholes are prevalent due to shale/limestone substrate. A nearby quarry using dynamite exacerbates issues by shaking the area.

Please, do the piping video. You mentioned Teton Dam, but may I sujest you take a look too at the Mariana's Dam disaster aka Bento Rodrigues dam disaster that happened in Brazil in late 2015. I think it wasn't just a bad planned upgrade to the dam or negligency, but a continuous erosion that was neglected and a last minute fix that could have made everything worse. Anyways, do make a video about piping.

Excellent video! I like all the demo setups you build. This is so much clearer and intuitively understandable than a diagram in a textbook (and I've seen a lot of those). I knew how sinkoles form, but I watched just to see you explain it the way you do. Thanks for making all these videos!

Fantastic visuals and information. Thanks!

I get amused on how there is always a quick demo for every video i've watched. Great work

Most of the world is water. Water is dangerous. We drink water. What is it doing inside of us?

Water is extremely dangerous if you are a crispy lifeform. Put a biscuit in gasoline - it stays crispy, put it in water - it softens and then dissolves.

Bravo! As an erstwhile Hydrogeologist I must say I’ve never seen these processes described better...

Very informative. We need content like this!

Great illustrations, very simple language ! Thanks for educating us all 👍🏼👍🏼

Very informative and great modelling…thanks Grady

Thank you for this very simple and yet very informative channel !

Grady, love your videos. Excellent explanations, scale models, photos, demonstrations, etc. Thanks for making these interesting and educational videos.

Just randomly came across this video. It was very informative. I learned something new and the visual demonstration helped me understand it better. Keep up the good work.

You need to make twice as many videos. Some of my favorite videos on the internet are yours.

Brilliant video, mate. Thanks for helping me understand.

why cant my lectures be this interesting

That was a neat simplistic way to view the process of sinkhole formation. I have my own thoughts on other things that cause them to form. Like downed foliage that ends up sub surface, or large root systems that are not excavated from the ground, after trees are felled, and are in areas that stay relatively moist and in turn decay leaving voids in the ground. My thinking is that gives a good jump start on the whole thing.

Very interesting! Well explained, this satisfied my curiosity just right!

Ótimo trabalho!!

So if I live in a basement apartment I’ll be gone first?? 😭😭😭😭

Wow! Your videos rock! They explain so much more than those civil engineering lectures back in school. Keep up the great work Grady!

Good stuff grady keep it comming

Thanks, Grady! I couldn't help notice the Teton to Oroville similarities. RE: Surfside FL, I see in the list that rusting rebar in concrete has already been discussed. MAybe in a few months when they have zeroed in on a few aspects you will have a video?
