There’s no way they have a debris grate at the bottom if they don’t have one of the top. There’s no chance they’d risk these getting clogged in a flood scenario. The best way to prevent debris from getting caught is to just lets the force of the water push it out and that’s not possible with a grate in place.

[@bobobaggins2034]

Yup no grate.. Patrick Dickinson has a cool video..Walking up from the outlet to the bottom of the hole.

Should be a fence or something going around, only a matter of time before a child or animal gets sucked in.

[@danlorett2184]

Yeah adding a grate to a discharge on a dam like this is literally just an enormous threat to the dam itself. If the grate plugs the discharge during a flood, the dam overtops and because it's an earthen dam, it quickly destroys itself if it overtops.

It doesn't make sense to have a metal grate at the bottom of the spillway ductwork. Without a similar one at the top, debris can fall in, but not come out. That would create a maintenance nightmare during high water times when the spillway is in use. They'd have to wait until after it isn't to clean out. That would create a backup and all kinds of problems. It would be better to have a grate at the top entrance and none at the bottom. I'm just speculating, but logic is in my favor unless I'm missing something.

I'm thinking, if the gate is removeable at the bottom it's much easier to remove the gate and let debris flow out. Having it at the top, debris can just pile up and it will take more effort to remove. You'll have to remove it, plus, transport debris away from the hole. On the bottom, you just move the gate and the water will take it away.

[@masonmunkey6136]

@@robertnicholls9917 yea you could have it like that but there's still no point

[@RobBCactive]

I doubt Severn-Trent Water completely lied, they probably have a metal gate at some point to discourage people climbing in from the bottom, though somebody apparently videoed themselves going in according to a comment. As for debris, it would have to cross the step too so wouldn't be large. It's a massive tunnel which flushes itself. The lake is large still water, so non-wood will sink as sediment. When water is flowing, it'll be an extremely wild turbulent rapid flow near the damn from the fall, it must open out then to a pool, slowed before entering a river or floods would cause rapid erosion and downstream damage. Perhaps there's a debris trap that would catch a body around that pool. I used to live in that area, the land around drinking reservoirs is managed, many have walks around them with gentle pasture leading to the lake which fills a hidden glacier cut steep valley. Unfortunately now it's impractical for me to go and have a close look, but Severn-Trent lock off access to their works. In the UK every summer people die from plunging into cold water or going over weirs, as rivers are canalised with managed levels.

If you fell into one of these, you'd go all the way down to the bottom where it angles (could be 60 feet, could be up to 100+ feet) and slam into the bottom concrete with maybe 2-3 feet of water there. You would likely die from the fall impact itself or break some bones and drown in the small amount of moving water at the bottom due to being unable to get back up. Even if you could stand back up physically, if there was a lot of water going over, the force of it beating down on you may keep you from doing so. You may or may not get swept on through the pipe. The area where it spits you out won't be fun, either...it's usually a rocky area on the lower side of the dam and goes right out into the deeper water. The rocks are usually to slow the flow and prevent erosion, of course.

[@dickJohnsonpeter]

That's fun to imagine that's what would happen but of course we all know that's not true. There isn't any sand involved like you said. It's actually water. But the water isn't moving it's a standing wave that looks like water is going down there. It's an illusion but in reality the hole is moving upwards at one inch per day. That's extremely fast. So fast you can't see it but instead ot makes it look as if water is falling down it. Then you have the problem of the Uncle. The Uncle is what's at the bottom and it handles all the incoming invoices. They built those things down the road so it's sturdy but not sturdy enough to hold a person. This is the set of R, Real numbers. The set a ∈ A is why. b ∉ A so if it isn't an element of this set you have to be wrong on weinis account about hitting the bottom.

In another video at this reservoir, the video showed the KZbinr fly a drone over and into that drain when the water was below the drain and had nothing flowing into it so he could get a video of what it looked like from the inside, but the air flow through the drain caused the drone to hit the side and fall to the bottom. He walked around and to the bottom of the dam to the discharge of the drain. There was no grate or gate of any sort at the bottom and he was able to walk right in until he got to where the drone was and recovered it. What is at the bottom is a box shaped pit that is open at the top with a ladder you can climb down and up and then a chute for the water that gets there to flow into the river. I figure the pit is designed to slow down the water flow so it flows into the river much more gently. Good thinking all-in-all.

When divers repair undersea pipelines it is vital that the pressure inside and outside is matched… if the pressure inside the pipe is accidentally set too low, attempting to spot weld the pipeline results in the diver suddenly disappearing, going through the tiny hole in the pipe he just made, and then there being red-tinted water with some grit mixed in it inside the previously empty pipeline.

There was an old hydro dam (Blode) near where I grew up. Even though it had been decommissioned for some 50 years water still flowed through the turbine intake. The intake is small enough that a human can't pass through, and the force of the water will prevent you from getting out. There were some five deaths like this before they finally removed the dam.

[@rockets4kids]

@John Thomas Yes, Bloede. But not everyone who died at the dam died from getting sucked in to the turbine intake. The spillway made a great water slide followed by a plunge and it was real easy to crack your skull on the way down, or land in a portion of the river that was too shallow, or get held under by the backwash. That's the source of the additional four deaths.

[@trueriver1950]

Yeah. Turbine intakes, and water inlets for water supplies, are far more dangerous than spillways, for the reasons given in the video: you have to try quite hard to get over the lip and would be unlikely to do so be accident. Same applies to traditional straight weir tops and plughole shaped spillways. What makes traditional weirs dangerous is that they usually have underwater sluices that, when open, produce suction downwards. Deaths in traditional spillways are usually due to people deliberately using the spillway as a giant water slide. Fun but dangerous for two reasons. Hit your head on the way down and while unconscious you tend to breathe water, which is not the life extending way to consume that liquid. Also where the spillway goes into the waterway at the bottom is often designed as a sheer drop. Like a natural waterfall, a sheer drop of water into water creates a circular motion (called "the washing machine" by lifeguards) that can swirl you round and round under water for longer than you can hold your breath. You can demonstrate the washing machine by throwing a football over a waterfall: often despite the fact that it's far more floaty than a human you can see it going round and round in vertical circles at the bottom before it eventually bobs up.

[@mr.dahliaking.202]

I live in Lithuania in a city where we have three lakes in sequence one higher than the other and they are not larger than maybe at most 10 square kilometers area each. They drain into each other trough small maybe 2 meter wide spillways and from the last one in the lowest plains drains into a river that goes to nowhere into some forests. Our city is planned in way that the whole city is built around these lakes and the city slopes down at a moderate angle and at the top of the highest lake is the peaceful side of the city where the apartment building reside and most of the people live there and then in lower regions are the job sites and all the business. So my grandpa told a story where during maybe 1960s there was a huge project to build 12 new 5 story apartment buildings (mind you this was in USSR so it was stalinovkas that were built) right next to the mid lake. The thing is that the concrete spillway tunnel that goes underground is not very deep and it is maybe at 5 meters depth, if that. So the bulldozers were digging trenches for huge complex foundations and they were like 30 meters away from the dam that held off the mid lake and right at the bottom was the burried spillway pipe. They were digging and one of the massive bulldozers hooked onto the pretty small 1.5 meter pipe and snagged it really hard because builders thought it was jus ta giant rock, and that caused the whole underground concrete foundation slab and the elbow to move significantly out of place in the bottom of the lake and it caused the whole maybe 10 stacked rings of concrete to fall sideways and the bottom elbow become exposed like a giant plug hole in the bottom of the giant tub. You can guess what happened next. My grandpa witnessed the entire thing. As soon as the rings fell and disappeared underwater a huge whirlpool formed and the water at the bottom of the jobsite nearby started to squirt like from a huge water mains pipe and the snagged concrete pipe burst and a huge maybe like 5 meter tall 2 meters wide water fountain burst out and the whole lake drained like a bloody tub and emptied in less than 10 minutes. It washed away every truck every bulldozer and every tree and every street and pretty much everything in its way when the flood rushed down the slope to the lowest lake witch was maybe a kilometer away from the mid one. I believe about 20 houses were washed away or damaged in some way but miraculously no people died. When he tells me that story I get goosebumps every time, I wish I could have seen that in real life. The mid lake got a new spillway, the new pipe was constructed much deeper, the apartments were built and now the same lake is again full and now the area is really beautifully done. But everyone who lives in my city knows that story of how the middle lake got drained away like a tub because some idiot snagged the spillway pipe thinking it was a rock.

Greatly depends on the type of dam. Concrete dams debris catchers like this are very common because they generally use a completely different method of discharge.

There is no suction unless the was experiencing massive flooding, then a whirlpool would be created and the subsequent current would steer you to the center. Under normal spilling the steps slow the water to reduce erosion and vibration. Under low water levels, anyone wanting to experience the overflow tube should enter the spillway tube from the base of the dam above the catchment ponds. Some have steps on the wall. Once in the tube just proceed into the dam, it may make small turns but eventually you will be able to se the sky and some of the steps. The tube walls will be slimy at the base and at an angle.

The feeling when you put your hand over a plug hole, is not suction from the drain (unless for some bizarre reason you have unvented plumbing). The feeling is actually the hydraulic head, that is the column of water, above your hand.

[@c4pt1n54no]

Wha... But... Would it not be more logical for the metal grate to be at the top? What purpose would it even serve at the bottom?

[@bill-2018]

I can only think it stops people walking up from the bottom.

[@c4pt1n54no]

@@bill-2018I feel like the transition would be so gradual for it to go from no flow to what's seen in the video. It'd be impossible to even get to the grates if it were already flowing. So you'd have time to leave. Falling on the other hand, seems much more consistently fatal

Fantastic video! Pretty amazing to have less than 1k subscribers but get over a million views. Fantastic! You clearly answered the questions that all of us were quietly wondering about, myself included. Your video production was very well done except for the last bit of video where, at the end, you can clearly see the water flowing backwards.

I just took the last bit as a kind of joke?

[@bsmbB]

wouldnt the metsl fence be a better idea at the beginning of the hole?

[@danlorett2184]

Unless the reservoir is really flooding and discharging huge amounts of water, it's actually not got a lot of force at the top of the hole. Most of the time when there is water flowing into the hole (a lot of the time water isn't high enough) there isn't a lot of water in any one place. It's probably less than an inch of flowing water, which really isn't forceful enough to suck you in - you'd basically have to fall in or be there during in the middle of a flood. Also there's almost certainly not a grate or fence anywhere along this discharge. The worst possible outcome for a discharge like this is that it gets plugged with debris during a flood. If that happens you can't get down there to unplug it and the dam will overtop and be destroyed entirely. They'd NEVER put a grate it something like this because it just creates an enormous risk to the dam itself. Without a grate, its VERY hard to plug up something this large. Especially during a flood where the sheer volume and force of the water will likely clear any debris out.

[@monhi64]

A grate at the bottom makes no sense to me. But a grate on the top hole dome shaped or something would at least prevent the deaths and is way harder to clog than one at the bottom. Yeah it’s not much force but still kills people and especially millions of animals, bad design

[@yggdrasil9039]

If they rounded out the bottom so that the alignment curved from vertical to horizontal in a gradual way then this would be perfectly safe to fall down, providing they got rid of the stupid fence at the bottom which is a recipe for drowning. I wish civil engineers would stop building unsafe structures.

[@WildGooseChase]

Sorry not to reply earlier and thank you for my first ever comment! The bottom is in fact curved and I believe that there is no fence. Check out this video: kzbin.info/www/bejne/hoTRiKZ9l6mirqc

[@krashd]

A recipe for drowning would be to alter the spillway in any way that idiots would think they could ride it, such as rounding out the bottom.

[@slickstrings]

yeah sorry, the driving design criteria for these spillways is the level it begins to spill at, flow requirement and the ensure it discharges the water in such a way that the energy of the water doesnt cause erosion. you can spend millions trying to stop idiots hurting themselves, but they will still find a way. this is an 80 year old structure. some personal. responsibility comes into it.

[@korelly]

There should be a safety fence around the entry of the spillway. That design is ridiculously dangerous

[@slickstrings]

@@korelly problem with fences, they catch debris which then resists the flow of water and can be damaged or obstruct the flow. They also rust. Again, this one was 80 years old and is not spilling all the time. If you decide to swim near an operating spillway after heavy rain events, youre probably not the brightest spark.

[@erictaylor5462]

There is a reservoir near where I grew up called Lake Berryessa. It has a plughole very much like this. It used to scare the crap out of me when I was little because it's not at all hard to imagine getting sucked in. The creek that fills and drains Lake Berryessa is quite well known. Officially it's called Prutah Creek, but it is really famous by it's nickname, "Green River." A "Southern Rock" band called Credence Clearwater Revival came out with a song about the creek in 1969. The funny part is, CCR wasn't Southern at all. They came from very near where I grew up, in California. Prutah Creek (AKA Green River) flows through Napa and Yolo Counties in California. One member of CCR grew up in my home town even. My dad remembers going to see them practice and play in some of the local bars in the late 60's just before they had their first hit.

[@ChrisClark_808]

Putah Creek.

[@johncarlisle621]

is this the same Green River in which Gary Ridgway dumped his murder victims?

[@SirFloofy001]

Its simply the most efficient way to move a large volume of water during a flood. The shape of the intake reduces the amount of turbulance introduced into the water which allows the water to flow smoothly into the drain. In fact it is one of the few drains that allows the full diameter of the pipe to be used to move water without air getting trapped as easily.

I live literally right down the valley from berryessa and it's absolutely insane what the lake looks like right now. I don't think the gloryhole has seen a drop of water other than rain water in the past five plus years. In fact for the first time in my life I actually saw the foundation and the bottom of the concrete case for the gloryhole as it enters the ground. I've never seen the water that low. The city that is in the middle of the lake basically came above the water. The Old Town bridge broke the water like multiple times over the last couple years. It would take probably two or three rainy seasons where we have nothing but monsoons for the lake to get filled up to the point where the gloryhole is ever needed again. If you want to look at a map of the lake and get an idea of its size. And then imagine that lake about 70 to 80 ft lower than it should be. That's about where it's at right now. Even though we have a lot of impressive mechanical marvels I think that humans are doing nothing but ruining this world.

[@WhatAHorribleNight]

It's not humans, you numbskull. It's called "climate patterns". If we have a lot of rain, it's blamed on mankind's greed. If we have no rain, it's blamed on mankind's greed. No matter what happens, it's all apparently due to mankind's greed - which can only be solved by the rulership of wise left wing bureaucrats, of course.

[@togglefire3537]

@@WhatAHorribleNight small brain go brrrrt lol trust me I've studied enough about climate change. And even though yes climate does change it has not changed this drastically in this quickly in this short amount of time. It's like you read the first paragraph about the research paper talking about that and now saying climate change is a myth. I'd do a sprinkle more research before talking about this again because no it is not just climate changing naturally. Humans are having a massive effect on it. Do you even know what carbon monoxide or greenhouse gases are? And the paper that you're referencing or trying to reference I have read in full. It states that yes climate does change naturally. We have had massive cold fronts and massive swelters of heat. But it's more of a gradual transition. If we were actually on a natural transition to a hotter climate, what's happened in the last maybe 50 years would have been spread out over more of 2 to 300 years. That's the normal trend in cycle. But because humans create gases and toxins that cause heat to be trapped inside of the atmosphere, and cause things like massive droughts that destroy ecosystems, all of this has a huge effect in climate change. I mean with all the trees burning in Europe from it getting hotter do you think that's not adding to it? And do you think all those fires just randomly started? Humans are a plague to planet Earth, or at least the humans that exist right now. Maybe our future generations will figure this out and stop breeding with people that think you're way, but until then this Earth is being slowly burned to a crisp from people with your thinking. You are wrong and before you even respond to me go and read that paper in full. Go and actually try to understand what they're talking about. It's obvious you never tried to read it in full or try to grasp the concepts that they were talking about because if you did it would have been completely obvious to you that humans are a huge factor in climate change. Stop reading titles and actually do research 🤪🤪
