• debris flow - 22 août ...
When you see it starts as a trickle and ends up pushing enormous rocks, trees and assorted debris its amazing that no more damage is done, due to clever design of channel. The power of nature is definitely a force to be reckoned with. Fascinating to watch for some reason, thanks for sharing.
the designer of these works is called fr.wikipedia.org/wiki/Paul_Mougin
It looks and sounds like cement slushing down the hill
You read my mind
Guys why dont build a piramid in wood, an empty piramid, and let a river of this fill it
OttovonEarth Actually it’s 2 out of 3 ingredients - there’s also water.
I bet it hardens like it too
I swear to Hades i said the same thing :D
why am I watching a weird cement river instead of sleeping?
Blurry Flag thinking of a concrete
BE the slurry river, all the way to the sea, far far away...
It's strangely soothing to watch and such a beautiful setting
Yup 3:30am here
Its, cute (nice and slow), weird (looks like cement) and frighting (boulders the size of cars just swim by).
Where does it come from? Where does it go to? What happens to it after the flow stops? How is the watercourse cleared after each flow? So may questions!
Ditto. Curious minds have we. I want to see what it looks like with clear water.
On google maps it looks like there was a massive land slide in the mountains. It looks like there's a lot of rock down river. It's the arc river in france. It was filmed on the corner of chemin tir and D79 IN Saint julien mont denis
just what i thought.
Sorry, I'm not familiar with french. Thank you so much for this video, as it is a crucial evidence for the force of mud and water. I'm in geology and search for all those evidence that these kind of flows can move tons of stones. So you do a great work to geology with your videos. Thanky again. Merci 🙏🙏
Thank you for your comment ! Glad these videos can help you
I am very interested to see the transition back from ciment river to river stream, or maybe there is some work to do to clear some stuff before that can happen ?
Just add lime and you got. 10ft thick sidewalk
War Phoine they don't needed metal too thick
@@minhnguyen5861 That made no sense. Why comment complete gibberish???
It looks like cement.
Where outside the chapel in sales
Incroyable la vitesse à laquelle ça monte !
Fluid dynamics in action, how to slow down a stream of fluids without making it rush down like crazy.
This is a textbook example of a Lahar. A mixture of soil. ash, rocks, boulders and other debris which has the look and consistency of cement.
The Energy released by these debris flows is off the chart😳❗️
When I see this I can only think of one thing, getting caught in that would really suck.
SO THIS IS WHAT HAPPENS WHEN YOU TURN OFF AD-BLOCK
Wow! That's wild! I've never seen a channel or canal like that before. Fascinating. That debris flow was getting pretty high. I hope the person filming was safe. Great video. Id like to see what it looks like afterwards.
I got nothing! And I'm still here to film other torrential lavas 😉
Tell the mason his building materials have arrived....
Me when idk where to put cement
This is how roads are made
Wow thats so cool, it's looks like slow flowing cement with big huge boulders mixed in, amazing the power
I thought that exactly..cement. notice how quickly the level rose. I looked at a house recently, and noticed it was opposite a river.This is why I changed my mind!
It does look like wet cement...
@@bb1040 More like concrete
guys it looks like million cubic meters of concrete
It's almost exactly like concrete. About the same consistency. EDIT: Like a lahar
concrete free
3:55 When you think you're done, but that next set of cramps come...
It’s like the have ten concrete mixer trucks at the top and using it as a concrete shoot
For a building site at the bottom of the hill.
Or maybe 100
That’s an impressive river of concrete you got there.
Brady, My thoughts exactly.. A site I was on had a blowout at the bottom of a 12' wall. The Geotechs told me they have concrete columns fail all the time . Lots of finger pointing. Sometimes the whole column has to come out, re bar and all...hugely expensive. Not sure if it would pass the slump test or have enough strength after 28 days. For those following, cement is the powder, concrete is the mix with aggregate and water,
Love the flows! How do they clean the flutes when the rain finally stops and they are full? Do they have dedicated crews who come in with excavators and such! That would be nice to see as well!
Looks like cement. Wonder if it hardened when it stopped flowing and dried
It always gets me when I see how big the boulders are that it is pushing along..
These mudflows are so weird, particularly how there are pulses of higher levels. I was surprised that the gutters across the channel didn't immediately fill up with rocks; instead, these all just kept moving and didn't get stuck. I would think these would have to be cleaned out regularly, particularly in the winter when it would be too cold to rain, and thus nobody could be caught in a flood while working.
no cleaning is done in winter, after the storm the channel was almost empty
Bonjour ,
J'ai bien visualisé sur satellite la localisation de cette commune et de cette rivière . La topographie est évidente , vallon court , haut relief très pentu , tous en ligne direct vers le fond du vallon . La bassin versant n''est pas gigantesque , loin de là ! mais en cas d'orage c'est inévitable ! incroyable et merci .
A t'on une idée des hauteurs de précipitations lors de cet orage ? et celui de 2011 ?
Et j'ajouterais, bassin hydrologique du Claret et massif de la Croix des Tetes dominé par des formations de schiste argileux
@@leane200618 non juste une image radar peu précise
As it slowed right down I got this over whelming urge to jump in feet first..!!!
OK I'll see myself out.!!
On dirait que c'est une personne qui a vidé sa bétonnière dans le ruisseau
Exactement.
J'ai pensé pareil
c est ro and cut qui on deconné
Cosson Gauthier rien compris.
regarde "ro et cut" sur youtube tu vas vite comprendre et bien rigoler. tu me tiens au courant!
The hydraulic force of water is amazing. It looks like wet concrete. Great capture.
Because water can't be compressed it will push anything and everything out of its way. The size of those boulders getting pushed like that. When will idiots learn not to cross a flowing steam/river with their cars. Every year all over the planet.
Awesome catch ! 👍
Amazing that the pressure is able to move those huge rocks & boulders.
c'est vraiment impressionnant, rien ne peut résister à une telle force !!!!
Les ouvrages de protection réalisés par le RTM resistent :)
what debri flow it looks like cement and where does it come from or is it mud
its a Lahar. A lahar is a violent type of mudflow or debris flow composed of a slurry of pyroclastic material, rocky debris and water. The material flows down from a volcano, typically along a river valley.
It's not a volcano!
its like a moving mass of wet concrete.
I return: Although the flood runs rampant along the prepared channel, it still seems to treat the flowering plants (to our right) quite gently.
4:02 That big surge just seemed to come out of nowhere 😮
Who ordered 152 football fields of ciment?!
153
Very nice catch
Why didn't you swim? Looks refreshing
Yes get a full body massage at the same time. Who wants a body massage, go
Cement is a powder, when it is mixed with sand and aggregate it is concrete.
@Richard Christopher Well, there ARE more than a few people having trouble with the difference. Good of fred to put it out there.
It is like beton (cement)
it's mud :)
How do we know they aren’t pouring forms out the pictures view?
Wow, not gravel and twigs then? It's amazing anything can withstand that pulverising force at all. Thanks for sharing.
It looks like a river of cement but its mud..... looks extremely deep.
Deve ser este feito da natureza que motivou o compositor Kiko Zambianchi a compor a música CHOVE e a musica Rolam as pedras...
Those are some big chunks of ice!
Fascinating. Thanks for sharing.
If cement mixers could dream...🤔
Where does it come from ?
That stream is having its way with boulders I would think twice about moving with my backhoe.
Question bête mais après ce torrent la boue est restee ?quel est la résultat après une coulée de boue paeillle ?
Most people would hall cement in a truck but I guess this works too......lol.
That's what it looks and sounds like,cement.
A passing gardener thinks "that looks like really good soil, I'll have some". Sticks his shovel in and hits a rock the size of a car.
IT certainly looks like a river of fresh concrete? - so does this /or other videos show where it actually ends up at?
6 pints of Guinness and a lamb biriani will do that to you.
*’INCREDIBLE’... & HYPNOTIC..!!!* :PEACE:✌🏼🕊❤️😎
No drink c est pas bon 😂😂😂👎👎👎
@@pascalbreizh4070 hbourrjp5rio7
What is the cause of these flows? Is it seasonal water melt further up into the hills?
Can someone tell ReadyMix their plant is leaking.
It looks like CONCRETE, not cement. Cement is an ingredient in concrete. Maybe this bothers me when people say "cement" because I am a concrete laborer. And it looks like about a seven inch slump, way too wet to pour. Lol
This is one way to deliver the concrete mix, albeit extravagantly wasteful.
Cleanup on isle two!
A Komatsu 575 is put to shame by the power of the water
I wonder how long it lasted.
Don't you just love it when controlling nature is so simple and effective
When the flow slows to a stop like this, does it set in place? If yes, then how is the channel opened again?
4:00 in some ,,weird,, way the wave looks so cool :p
That's not debris flow, that's a mudslide
a free supply of cement to all Carpenters living near by is like a gold mine
Where did it end up ?
Life on Quickcrete Mountain.
Does that happen often?
Noeraldin Kabam Yes, every year for the past 350,000,000 years.
Pretty sure that is cement at some point.
BE SMART... NEXT TIME MOVE THE CAMERA TO THE OTHER SIDE TO SEE HOW THE STREAM GOES DOWN... THE LOCATION IS REALLY BEAUTIFUL WATCHING THE OTHER SECTION ON THE STREET ... VERY BEAUTIFUL... URIEL, PANAMA CANAL, MAY-29-2020
"and that, boys and girls, is how we made the new road" :O
As people have said, just like cement. How amazing. Where was it?
France near the Italian border I think
Someone at the cement factory just lost their job.
Belle prise, dommage de ne pas l'avoir prise également un peu plus en amont. Le fait qu'il y est une telle épaisseur de la lave est dû à quelle phénomène naturel, alors des fois ça peut être uniquement liquide ?
De plus dans quel état est le torrent maintenant ?
C'est naturel oui, de fortes pluies. C'est assez rare que ce soit aussi visqueux. Très souvent c'est liquide. Voir : ruclips.net/video/jgWbYDUm-ME/видео.html
@@alexandre.modesto Woher kommt das ?
3:05 Is this a concrete or cement river?
It's cement left over from a building up the road
السلام عليكم
هل من احد يفيدني ماهذي المواد السائله التي تجرف الصخور العملاقه
هذا سيل من طين.
And now we know why the canal was so deep to begin with.
Сколько форели смыло???
Some of those boulders where huge.
This would be a great place to open up a terra-cotta shop.
Lots of concrete is flowing. Are you building something ?
Yes. Nature is building a new earth
Holy crap, that's crazy. Why is it so thick? It looks like concrete.
mudflow
Because a lot of rocks (small and big), "rock powder", sand or just mud (also with organic material) is suspended in the water. Density can reach up to 2,6 g/cm³ (= t/m³ = kg/Liter) and therefore is as "thick" as concrete. Thats also the reason for some rocks floating around.
The "mud" and all the rocks is washed down from the steep hillsides in this vast mountain bowl north of the town, when long and/or heavy rain events take place (e.g. strong Thunderstorm), and some loose material has accumulated over the years.
I think the heavy rain event is the trigger for Alexandre to be at his spot at the right time. And an informant upstream e.g. at Montdenis, which hear the rumble a little bit earlier ;)
Great footage and Timing !
Motivating to watch if you suffer from constipation.
I was shitting while watching and reading your comment. 😅
Wow!! Some of those bigger rocks must be around 2 it 3 tons...!! Just shows you: when it's you Vs mother nature, you'll mostly come off second best!
Is it ash from a volcano? How do you spell lahar??
Nitwit.
@@samfrancisco8095 your problem is? Typical CA idiocy.
This is like the morning after taco Tuesday at the Moose Lodge.
Does this all end up in the ocean ?
Right when youre about to jump and a wave comes
Notice how easily water and mudd pushes rocks that weigh as much as a car?
A rock that is a cubic yard weighs as much as two average sized cars.
wonderful
wow,floating rocks ,thats new
So, just where does all this "stuff" end up going.....river..?? lake..?? ocean..?? Thanks.
rain simply
Bells ringing to warn everyone downstream
Good god! Either Godzilla is unloading a number 2 upstream or they are downloading enough cement for another mega dam downstream.
