Model Dam Fail

[@CockpumpVideo]

probably why dams arent made entirely of sand

[@GreasyOaf]

good point

[@G1NZOU]

Some are made of compacted earth, just depends on the style of damn used, the quality of construction and weather the ground is capable of supporting the weight of the damn.

[@JHA854]

Idk, if it took 3 minutes for a dam of this size to fail, if you scaled it up to full size it would probably last like at least a year, not bad.

[@GreasyOaf]

J Hughes its still more cost effective to just build one that would last longer though.

[@shhhlemmesleep]

The same "dam" question I ask myself every single day😂😂😂

[@Catorak]

So you're telling me that if the water gets higher than the dam, the dam stops working? Wow, fucking crazy.

[@weirdkidpilot]

The water didn't get higher than it per se, it was that the material the dam was made of became Saturated and weakened and the dam itself slipped lower than the waterline Ultimately what caused the failure was the saturation though.

[@GhostyGhost7007]

Dom Wilsher They kept the hose running water

[@Nate_HarietteYouTube_Adventure]

Not properly compacted with proper soil and water level to high

[@johnking2631]

you don't build a dam and leave it at water level or near water level...this is a sad attempt by a Eng student or w.e

[@allencarbon7197]

It's to reenact rain water or any real life situation. The water never went higher than previously. yes they kept pouring more water in but that was just to keep it levelled. The water started receding due to water absorption by the soil. in real life, the water level would remain as high or even be higher due to flooding.

[@davidrodgers45]

This isn't a real world example of how an earthen dam is built. They often have waterproof faces on the reservoir side - usually concrete but also could be large rubble or other protective substances. The core of the dam is given an internal layer of waterproof material like clay or some types of silt that are very water resistant. The dam is expected to become waterlogged in certain areas so this is calculated and pathways for unwanted saturation are provided inside of the structure. Then the internal water barriers prevent the water from causing the fail that is shown in this video. Basically, this video is as big a waste of our time watching it as my time was in trying to make the truth of the matter more clear.

[@tongshen6610]

Best comment so far, getting some knowledge here instead of reading people yell at each other.

[@leonardoturtle9749]

They also don't make dams out of sand & gravel without a liner. Clay yes, but not sand. No built in overflow, no secondary overflow. I can't really see how this would have been helpful to the class unless it was to demonstrate the need for building in overflows & intentional breaching points.

[@nicksmith4449]

A waste of time? I mean... ok. If you're completely uninterested in the failure modes of a simpler design choice. Or if you're uninterested in in what happens if the concrete fails. Or if you're uninterested in how saturated areas behave. So if you're uninterested in dam failure modes, this is a waste of time. Basically, if this video is a waste of your time, you should have known that before clicking on a video about dam failure modes.

[@1969cmp]

David Rodgers Which was probably the follow-up experiment, to use some kind of water resistance, clay, rubber and cement.

[@sasukeuchiha998]

I believe this was to show kids the necessity of intellectual individuals who can come up with a better design, in order to spur children to get into engineering and other fields that are useful. I for one remember being told that we needed more people in public health, and experts in water treatment facilities as the city I lived in had a hard time with getting enough labor for the not so popular career choices.

[@759NPR]

This is a poor representation of hydrolysis & soil compaction. Water travels the path of least resistance, and the saturation of the soil seen at the bottom/side of the dam demonstrate this point. Dams aren't built with sandy/silt soils, above/on a slick, non-binding surface. Clay is typically introduced along the bed and walls of an engineered dam base or pond, and compacted in layers to prevent major soil movement. The presence of the water against a clay embankment changes the orientation of the clay platelets, the basis for soil movement/hydrolics and even though the hydrolics, at some point, would be present all along the dam base, which is the soil movement in this instance, that lateral force is retracted by the sheer mass of soil behind/beyond the water point of contact at the bottom of the dam. All soil reaches a "plastic" state, when its saturation reaches a certain point causing hydrolics or, movement of soil. Compaction is introduced, along with aggregate at times, to counter act or stabilize the wall of any earthen barrier in the presence/possibility of hydrolics - soil movement. Engineers typically formulate bearing pressure against soil when introducing a load, or, in this instance the hydrolic pressure of the water when calculating resistance. It's the same approach used when the federal highway administration built the interstate systems all across the country. When they needed dirt to fill a grade in the roadway - to bring a stretch of highway up to grade, they excavated ponds along the route - some of which became retention ponds for roadway run off from storm water, and then lined the base of the ponds w/either a sandy clay or a non-porous fill so as to contain the water in those ponds, keeping them in place. That salvaged many man hours/hauling fill needed to bring the right of way up to grade, and allowed for efficiency & economy. However, the fill placed in the road bed from what was available within the construction right of way wasn't always stable soil, hence, the constant & ongoing paving/resurfacing of some of those roadways, due in part from poor/unstable soil placed in the right of way...but that is another conundrum.

What a huge waste. So you mean to tell me the dam fails when you pour water up to it's very apex? You guys couldn't wait another 3 minutes to watch it fail reasonably you had to keep adding water until it nearly crested the top and washed it away.

[@MalcomHeavy]

That was my thought. Like, "Hey, Dams aren't meant to be filled to the crest damn it." Can you idiots really be that stupid? I'm sure even the Hoover Dam would collapse of filled to the brim. that's why we build them far higher than the water level can reach. All this proved was that those teaching our children are dumb as fuck.

[@Christdeliverme]

It was a dam failure that's for sure...

[@jjmonns]

I believe the idea was to demonstrate why they fail. Sometimes the water does get too high, that's why floods can be so catastrophic.

[@Christdeliverme]

+jjmonns that's what levys are for, no? A dam is about fluid control and I think they were trying to demonstrate a failure in design not in height

[@jjmonns]

Beau Mancini It's levee. I live in SC and here you can't go 10 feet without crossing over two earthen dams as we have manmade ponds everywhere. Many of them have roads built over them. Dams allow water to escape to keep the pond at a semi-constant level. The problem is that during a flood, such as the one we had here recently the spillway goes over capacity and the level rises too high. Many failed, just like this one causing a lot of roads to be washed away. If you notice in the demonstration they filled it to a certain height and let the dam full saturate with water. It was not until after they continued to fill it near the brim that it failed, which is how many dams like this fail. Yes, large scale civil engineering projects for things like hydro plants and so on use concrete and other measures to ensure safety and security but there are also plenty of examples of privately made dams used to create manmade ponds. Many use secondary spillways or breakpoints where they are designed to fail in a controlled manner in the case of a flood.

[@JodianGaming]

I've never seen such impatience before. Put the water in and leave it, don't keep putting more water in. The more you artificially disturb the test the less accurate it'll be. I was looking forward to watching the sand penetrate under the dam, flow through, and cause an erosion collapse at the base. Instead, because they kept adding water (and causing high currents) it eroded away the top of the dam and caused a landslide.

Imagine being the guy who designs dams and basically getting to play with oversized sandcastles for a living.

[@eriche882]

This shit doesn't mean any thing. If it is a RCC dam, there shall be a CORE in the middle of the dam and a water proof surface against the reservoir, the core can strengthen the dam itself and the concrete surface would stop the soaking. This shit won't happen in real life, no one would allow it.

[@23ofSeptember]

There are probably thousands of earthen dams like this around the world and many fail every year for this reason. Google the Testalinden Creek dam failure in British Columbia in 2010. Its important for engineering students to learn about why dams are constructed the way they are today and learn about mistakes that were done in the past.

[@eriche882]

Consistently Random yes, agree with your point. we do learn things from mistakes which makes today's dam construction specifications improved. Still, I'm going to say this is not allowed in real project, it's just a model to show how a fail project works....

[@mysterioussquirrel4456]

Are you for real?

[@trip3980]

Its a good experiment shows that a basic dam needs more structural engineering if a flooding where to take place. I agree that their are many earth damns around the world with no support. Videos like this would save lives.

[@garretttanner9788]

By putting the dam in that container they made it easier for water to penetrate at the edges, combined with the fact that this was done with bare dirt when earthen dams would have at least grass to prevent erosion made it much easier for the water to break through.

[@whiteknightcat]

Suggestion for the next demonstration: DON'T OVERTOP THE FREAKIN' DAM!

[@Cruxair]

Why is it a fail? The decription says that they wanted to show a dam collapse.

[@jeffc5974]

The dam itself didn't fail. The water pressure overcame the coefficient of static friction with the plastic it was sitting on.

[@lucaswinsor4469]

Because when something collapses, it's called a Failure.

[@lucaswinsor4469]

You have no idea what you're even talking about. It doesn't matter if it was created for that specific purpose or not, the term Failure, in this instance, is a technical term referring to the collapse of the structure. Even a SIMPLE google search would have told you that.

[@doctortabasco]

For me, it's pretty obvious that if you full one side of the dam with water, overpass it, it will collapse anyway

[@ismaelrodj]

Sirdavitian No. We are talking about a specific type of dam here. Concrete dams resist the collapse even when they are overpaased by the water. If the result is different depending on the type of dam, then it is not that "obvous".

[@phrog849]

Ismael Rodríguez who makes dams out of dirt?

[@filipeazevedo1154]

There's all kinds of dams made out of dirt (rocks and sediments, but let's call it dirt). Most small to medium size water reservoirs are made with such dams

[@stephans1990]

Yes, but covered with rock or concrete and clay to prevent water from slipping trough.

[@iniquity7]

Schnitzel_Stephan yes and that stuff cracks over time so water will seep in then u have something like this happening

[@venomousvoltage]

This is an inaccurate model for two main reasons. 1.The pressurized jet of water from the hose does not exist in a real dam. 2 That whole chunk of sand sliding to the left is caused by lack of friction between the sand and plastic bottom which again is not in a real dam.

[@realdeal5712]

[@nikhil3155]

[@leonardoantonio8756]

[@skeetajohnson]

[@stoutyyyy]

It was to simulat current

[@gamma_dablam]

Was given to children. Certainly would prefer this demonstration to a lecture on the physics behind it. If I knew the physics

[@alexh3974]

It also simulates extra pressures and forces that could be put on the dam. Water is not always static.

[@agonleed3841]

Alex H water isn't static. But not ALL dams are built in high pressured areas. Especially this type of dam The movement of water on this type of dam isn't so directly forced as this. Bot this type of dam. By the time it reach3d the hills, the water really should've been a bit more stable than others This simulated a strong concentrated force all at one time and continuously throughout. Now...if they're simulating the idea of "build a damn for an incoming passage of water....then, yes, the builder failed. But if the goal was just to simply hold water....this was a bad way to test it. Then again......

[@Notsure00700]

Impressive, but from a hydraulic engineering standpoint, the model is floored. It failed only because of the water pushing the base of the sand along the slippery Perspex bottom. In reality dam walls are not built from sand, they are built from reinforced concrete. The base is also tied in deep and anchored.

[@beobe99]

Both the bottom and sides were slippery too. My problem is sand itself as water absorbs into it pretty well (as seen) and causes a sort of "float" to the structure and / or lubrication in between granules (that's my theory at least, may be flawed, not a structural engineer here).. So, of course it's going to break down much like a Sand Castle on the beach while it rains... If it HAD to be a Natural structure unlike what you mentioned (the way to go) a Clay substance should be used to hold everything together and prevent water seepage..

I didn't knew that dams were made of soil. -__-

[@Fx_Explains]

Opals Bodhi what are you saying 🤔

[@crazypiratesquirrel3038]

Google "Earthen Dam" (also known as an "Embankment Dam" or "Terrain Dam"), they're actually fairly common. 🙂

[@crazypiratesquirrel3038]

Johnfuse Yes. You are totally correct!😄 But Tushar Chaudhary made a statement that they didn't know there were dams made of soil, aka dirt or earth. I thought maybe Tushar live near a bigger city where there are mostly huge man-made concrete dams and therefore had never heard of earthen dams. I lived in a rural area where these dams are more common. I suggested looking up earthen dams because I thought websites would be able to describe and explain the science behind them much much better than I could ever possibly hope to. 🙂

[@zettle2345]

when you make an earthen dam... you usually put a layer of clay in it to stop the water from soaking through it. they been lining fish ponds with clay since the Roman times, or before.

[@ardrej]

exactly an impermeable core is used in soil dams to stop water from penetrate

[@pawanv86]

I feel bad for the person who built this. 11 million people saw it fail. 😂

[@TurboMitsubishi]

Shouldn't the "bed" be dirt as well and not plastic?

[@Malus1531]

Interesting point. You'd think the sides of the "dam" near the bottom would be less likely to start sliding if there was more dirt instead of smooth plastic. Maybe it's not practical on a small scale though. A thin layer of dirt might just be stirred up into the water.

[@logdog6762]

You will lose water to seepage downward in a realistic sense, but this model still illustrates how a dam failure can occur.

[@sigitato9525]

yes

[@turgsh01]

All it needs is a gritty surface instead of smooth plastic. So if you glue a thin layer of sand or w/e to the walls and bottom, you'll have a gritty surface. But in my opinion... only morons make dams out of dirt / sand. They didn't even need to have the water level that high for it to eventually fail. Sand is like a wick... it just soaks it all in and eventually the slightest vibration will collapse it all. Concrete and steel/iron is the only way to go. Though even then, they go as cheap as possible which is why even those can fail.

[@logdog6762]

***** Yes, in a realistic sense, in a realistic dam, you would get water seepage in all directions. However, this model is only designed to detail failure due to seepage into the wall, which it demonstrates just fine.

[@020Dutchy]

Why is that fool moving in front of the camera repeatedly

[@Elfnetdesigns]

2:01 = just what we wanted to see..some persons backside.. This is not a very good example because levees made of dirt are not generally build on top of acrylic sheets or out of sand.
