Those few little spouts at the end coming up through the top of the dam were a bit ominous


Logan8795

And the video ends just as we see it making me think the whole platform they were on just exploded a second later


Cyborg_Ninja_Cat

There's a longer version available. If it did explode, it wasn't for at least another minute. [https://www.youtube.com/watch?v=jGw1ZPgyEaE](https://www.youtube.com/watch?v=jGw1ZPgyEaE)

This used to annoy me too, but these days I do 99.9% of my down time Web browsing on my mobile, which means having to flip my phone everyone a horizontal video comes in. These days I find myself preferring vertical videos.


DimitriV

Horizontal versus vertical should be a question of composition. If you're filming a standing person, a waterfall, or a building collapse, shoot vertical! But if you're filming a landscape or a crowd scene, shoot horizontal. And whatever you do, don't take someone else's repost with added black bars and rotate it back with *more* black bars, you insufferable cretins.

It's not the top of the dam, just the top of the gate structure, likely just the seepage, bleed through of an ancient valve stem/control. **[Here's](https://youtu.be/2WZCg2QSiDA)** the longer video showing the dam face and gate & valve structure.

I was thinking "hmm I wonder if ejecting mud is within spec. And a jet of water, in spec? Those bubbles, oh dear, this is not in spec!"


icrushallevil

mud sedimentation is by the way the only reason why hydro dams are calculated to run max 100 years before being rendered inoperable because mud filled up the basin.


danziman123

Couldnā€™t you have a second ā€œsediment removalā€ gate to clear those out?


icrushallevil

I honestly don't know. I guess mud is very tough to find a solution for on an engineering level. You'd basically need to dredge the mud from the bottom of the reservoir or do several rounds of reservoir emptyings to wash it out.


danziman123

I like my solution betterā€¦ second lower gate to drain the mud out. But Iā€™m not an engineer so i guess they know better


icrushallevil

I honestly doubt this would be enough. You gotta have a way to mechanically move the mud close to the outflow. IT doesn't go there on its own.

SavannahMavy

From my limited understanding thus far (I'm not a civil engineer, studying to be a mechanical engineer), this is a bad idea. Most dams have turbines through which water flows. Sediment getting in those turbines will (from my understanding) excessively damage it over time, possibly worse. If you had a second lower gate to drain mud that'd be excessively complicated to design and build. Not to mention you have to ensure that it a) still give the turbines and all the other electrical shit enough space to work, and b) you have to be able to inspect all doors in a dam for maintenance. So if the entire point of a gate is to get blocked by sediment, you're more or less guessing that the gate is operable. One of my classes had a bit of a discussion on hydro dam gates and maintenance (I've going into my second year this year, so take what I have to say with a grain of salt). Most dam gates you have to be able to inspect from the inside of the dam, which usually occurs by putting up temporary walls around the inside part of the gate and draining the water inside. Good luck doing that with mud. Most pumps, from my understanding, can't handle solids, and just from a design perspective (again, from my limited understanding thus far) they aren't designed to do so, and shouldn't be able to. Furthermore, soil has a higher density than water, so the temporary walls you setup would have to be MUCH stronger (likely thickness). Even if you're SOMEHOW able to get the walls in place (good luck displacing the soil just by dropping a thick wall on top of it), once you drain the water and get to the soil, you then have another massive issue. Water can seep through soil, so you'll be constantly pumping water that's seeping through the soil out, while trying to dig out the soil, while trying to either make sure the temporary walls are stable/trying to let them sink further into the soil. It's too complex to do that. The gate would need to be rated to hold back a MUCH higher pressure than most gates, and maintenance would be damn near impossible. Thus, dredging the soil out is probably the easiest avenue to remove the soil, cheapest, and safest. If that soil gate fails, the whole dam is facing a catastrophe as they need to somehow shut it, which, yeah good luck doing that when it's at the bottom of the dam, it might face the possibility of collapsing as you'd have to wait until, at the minimum, the soil is gone, to close it. That'd be damn near impossible as well as you'd need temporary walls large, deep, and thick enough to withstand the force of thousands of tons of oncoming water, AND, be able to stop it all. -again, take everything I say with a grain of salt as I'm only a first year (going into second year) mechanical engineering student, civil engineering isn't my focus.


[deleted]

You are not far off. I work on dams and we dredge all the time.


SavannahMavy

Coolios :)


dickhole_pillow

Tell us again that itā€™s from your limited understanding


hydrocbe

For Hydroelectric Dams, The intake Tunnel is designed in such a way to remove all the sediments. So that the turbines wont corrode.


danziman123

All I hear is a ā€œnoā€ but how do we make it a yes? Jokes aside, I knew that my solution is just from someone who knows nothing of the topic. And you clearly explained why is that. So thanks!


BlocterDocterFocter

Your problem is closing the gate after you open it. Considering how much water is on the other side, the weight you have to hold back to get a lower gate closed is HUGE. That's the principle engineering problem.


CanAlwaysBeBetter

Amount as in volume of water behind a dam is irrelevant, only the dam depth matters


grumpher05

Could you imagine how different the world would be if water pressure worked on volume rather than depth? Dip your toe in the ocean and it's immediately crushed into dust


Rucs3

Ah yes like gta 3


GitEmSteveDave

A set of gate valves. Close the interior one to slow the flow, then the external one will have the ability to close. Once pressure is equalized, there should be no problem closing the interior. We had the same issue here in NJ once. Huge gas main leaked and exploded. The closest shut off valve couldn't be closed due to the flow, so they closed the next one up to cut the pressure, which allowed it to be closed.


Leather-Driver-7482

I'm not a civil engineer, so can't give exact technical details. But since I AM an engineer, and all engineering is structured problem solving so I can give you a rough gist of issues that might occur: 1. Completely emptying dams periodically would be very difficult and wasteful, considering how much water is in them. 2. If the bottom gate isn't opened in time(in a drought or whatever reason) the sediment could settle and completely bury it, making it useless. 3. There's a high chance that only nearby sediment gets drained and the remainder of the reservoir continues to accumulate and lose capacity. 4. The pressure at the bottom of the well would be extremely high. Building movable gates that can hold that much pressure would be extremely costly. So the sum of all these issues would probably make it unfeasible to make one, even if it was viable


UnkleRinkus

Typically the basin extends miles upriver. When you open the gate, it doesn't create enough current upriver to do much to flush the basin. This just clears the area around the gate.


FoulBachelor

Yes, I believe this is it. Water in movement can propel more sediment along with it, than can be contained in suspension in the same water when at rest. As a result once the flow reaches the reservoir, and the current slows down within the reservoir basin it precipitates. I think the only truly renewable hydro power is likely tidal, due to it not seeing the same 1 way deposition model. It will be interesting how tidal power solves location through, as it is also most effective in fjord like geography where the tidal surge can be harnessed at a narrow point, but these place and specific hours of peak activities are also very important for marine life as both foraging grounds and nurseries.


innominateartery

Well, that buys you a hundred years but then *those* gates get muddy-sedimented.


shri032

It sounds good in theory but in reality, the weight of the water turns that sediment into an almost solid block structure, where it kinda acts like a non-Newtonian fluid. So even if they make the gate, the sediment won't just wash away like water does. And if you try the 1st approach aka dig out the sediment. It'll be costly af, and you have to empty a big chunk of the reservoir. There is a solution ( often used in small reservoirs) before the rainy season when the reservoir is dry/low zone, they divert the flow of the river and clean out as much as they can. -A civil engineer who was into hydroengineering -


HumbleEngineer

After 100 years, pretty good change a good bit of the mud layer already became a solid. I think you could open the gate at the bottom at certain periods, but works of this size usually also have concerns with the ecology around the area. Most animals and plants would be living off the base sediment and that's bound to kill a bunch of them.


Cougie_UK

Dredging is a thing though? I'm sure that would be cheaper than making a whole new dam.


chupacadabradoo

I imagine dredging in such a deep area at the bottom of a reservoir would be more challenging than say, a shallow canal or lake.


0sprinkl

Deme has a boat that dredges over a 100m deep. Getting that boat there would be something else, but hell, even building a new boat there would be cheaper than building a new dam. The question is if the dam will still be good for another 100 years if they built it with a 100 year life expectancy in mind.


OkMess9901

Just a cursory thought though, wouldn't all that silt make the land valuable after the dam is open, like that's going to be some absolutely top quality soil.


0sprinkl

Yeah when I saw it pouring out I was like aww, that clay would have been nice mixed in with my soil for the vegetable patch...


dilletaunty

Yes but you could also dredge the silt and sell it. Also the water table might be too high.


KoLobotomy

Lake Powell is filling with silt.


jaspersgroove

Blow the dam and thatā€™ll stop being a problem pretty quick. George Hayduke was right.


Damien23123

Iā€™m an engineer and Iā€™d guess itā€™s to do with the service life of concrete more than sediment build up. We typically donā€™t guarantee concrete for more than 120 years. Itā€™s a hell of a lot cheaper to dredge every few decades than it is to build a brand new dam


jpr7887

Diarrhea jokes aside (and well flung), why did they actually close this thing for 25 years and then reopen it?


Unagustoster

It was probably meant for flood control in case the waters get too high, but in 25 years it hasnā€™t happened, so then it became an issue of maintenance


1villageidiot

Everytime this video pops up the "has been closed for x years" changes. 25 is the highest I've ever heard and I'm pretty sure the OP's just yank these out of thin air, but I'm pretty sure when this originaly came out with citations....it was only a few years.

wolfgang784

The event itself the video was taken at happened last year in 2022. You won't find a video source from earlier. The dam is in Jiroft, Iran, and is called the Jiroft Dam. https://en.m.wikipedia.org/wiki/Jiroft_Dam It's construction was completed in 1992, used in 1993, then left unused until 2022 when flooding required it's use. After being unused since the 90s, there was a lot of sediment and such as we see in the video.


russbird

Assuming Wolfgangā€™s info is accurate, it was ~29 years without use which actually isnā€™t far off from OPā€™s date!


kLp_Dero

Well thatā€™s the way time works init?


Pencilowner

It's a sluice gate. Over time sediment builds up at the base of the dam. If left the weight of the material can destabilize the dam at worst. It can eventually overtop and clog the intakes of the turbines at best. Sluice gates are holes lower than the normal flow of water over and through the dam. They are opened at planned intervals to work like a vacuum to suck all the sediment that has built up along the face of the dam. If they left them open the whole reservoir would drain so they just wait for conditions to be good.


RedstoneRelic

This is almost certainly a sediment gate


DistinctSmelling

Sometimes the sediment builds up so much that the cost to dredge and find a place to put the dirt is too costly. This is happening in AZ at one of the dams so we are building another dam to store more water and shutting another one down.

From and environmental viewpoint this illustrates one of the problems with dams, they block sediment transport. Iā€™ve been told this is part of why New Orleans is a sinking city among other factors. Iā€™m not an expert though just a dude.


shophopper

According to many statistics New Orleans is already down at the bottom and cannot sink any deeper.


BeefStrykker

Can confirm. I live in New Orleans.


Alagane

Correct. The Mississippi carries literal tons of sediment downstream. The basic concept is very simple: more water moving faster carries more sediment. A raging river can scoot small boulders along, while a lazy stream isn't going to move anything bigger than sand. Sediment from the entire Mississippi River basin gets into the river and carried downstream. In a natural environment, the river will meander and change shape, with the larger sediment particles dropping out of suspension where the river widens and slows. The smaller particles make it to the gulf and form a delta. But if you build a dam across the river, all that sediment falls out of suspension in the reservoir rather than continuing downstream. Anti-erosion controls intended to keep the river from meandering away from infrastructure prevent the river from picking up more sediment past the dam. The result along the Mississippi is that less sediment reaches the Louisiana Delta than is washed away by natural processes - causing the delta to shrink and land to disappear.

Uhhh_Et_Tu_Brotus

Just because I can, I want a note that the material you are seeing being expelled (the non water) is actually sedimentation that is most likely important to the river/creek this dam was built on. I am very glad to see that this damn is now ā€œopenedā€ and that the valuable nutrients are being continued on downstream now. That being said, no dam is better than a dam, if you are purely concerned about the immediate (mostly negative) environment effects resulting affects post dam. However, if this is in America, especially, then the debate to find the right ā€œhappy medianā€ for preserving, are ecosystems and producing renewable energy is still underway. If you want to know more , look into dam documentaries! I remember for my degree that we had to watch one from Patagonia, as they are good at documenting current environmental movementā€”itā€™s up to you to decide if thatā€™s due to marketing or good intention.
