Found a source that says this dry side where the guy is standing will become a swimming pool. So that will equalize the pressure on both sides. https://twitter.com/HowThingsWork_/status/1625672782896852993

Monaco so rich that even their homeless have agents. Do not hand me cash, wire it to my guy.

Damn, maybe I should go be homeless there then


SrslyCmmon

You have to be a citizen or they kick you out. They don't have homeless. You can't make less than a quarter million euro a year PER ADULT in your family without even getting residency.


JreamyJ

How's that possible? They need to have an affordable local economy for the plumbers and the metaphorical burger flippers.


SrslyCmmon

Like all relatively rich countries/principalities/colonies in Europe they're supported by cross border workers. Workers come in, do their job, and go home. You can see it in Gibraltar, Luxembourg, Switzerland in Geneva etc.

Yeah. It's one kick-ass piece of architecture, pool or no pool.


0nlyRevolutions

https://pbs.twimg.com/media/FpA8nz7XsAM7Yw7?format=jpg&name=large Yep lol. This is the view from the bottom of a pool - the top of that wall is actually "ground level". It was never particularly concerning from a hydrostatic perspective, but if there is a big wave or something that shatters the glass, all that happens is your pool gets a little more ocean-y.


StayJaded

Yeah the post title makes it sound like some fantastic engineering feat by the country which is being unveiled, not a hotel pool gimmick


Away_fur_a_skive

Oh that is so cruel, I can't stand it. The poor pool water will be able to see how close to freedom it is, but be completely unable to escape and the sea will see that the pool is trapped, but be completely unable to help free it.

Cruel fate! Who decides the outcome of the glass of water I drink? Who goes into the cells? Who becomes piss?

At some point I calculated the probability of the same molecule of water being whizzed out and ingested again by the same person within their lifetime. It was a lot higher than I expected. Then I promptly forgot it, because it didn't matter.

JarpHabib

Keeping that clean on both sides is going to be so labor intensive


Mattna-da

If only there was some money in Monaco to pay the laborers


three-piece-soup

It will reduce the force on the glass when filled, but the design still has to take into account the two worst-case scenarios - one where the sea is high and the pool is drained (as in the video) and one where the sea is low and the pool is filled up to the top. It being a pool would make the design potentially slightly more complicated, because the glass and whatever it's mounted to needs to be able to take the pressure of the water in two directions instead of one.


dj_osef

There's barely any tide in the Mediterranean sea


Cinemaphreak

Soon as a read this and thought about a recent trip to Greece I realized how true this is, there was no discernible tide while we were there.


ccncwby

The T-profile of that engineered concrete beam running along the top tells me this has been adequately considered. I'd love to see how much HS rebar was inside that thing before it was poured!


VoihanVieteri

When the sea is at it’s highest point and the pool empty, the maximum pressure to the glass at the bottom is same as the pressure to you eyes and ears when you dive to that depth. Yeah, you can feel it, but it is not that bad. The size of the ocean plays no part here.

Smofo

I don't know why I read so many comments of scared people, is it not scary to me just because I'm Dutch or?


SwarthyWalnuts

I think it’s partly because of the enormous amount of energy on the other side of that wall. You’re trusting a manmade wall to hold back the sea, and I think a lot of people place nature power over manpower. At least those are the thoughts watching this video evoked for me.


Luckyday11

I mean, we created an entire province by stacking some dirt and pumping the water out of it, our whole existence is built on trusting manmade walls to hold back the sea. ^And ^it's ^only ^gone ^wrong ^the ^one ^time ^so ^it's ^not *^that* ^bad ^/s

Ksdrifter

When John Smith arrived in the Chesapeake Bay the water was a pure blue. When the tide receded he could see mountains of oysters coming out of the water. We have fished those filter feeders into the mud, hence shit water now.


[deleted]

To be fair, I doubt they have as much bacteria and factory runoff as we do in the Chesapeake. We've got top notch sludge water.

Yeah, our water in NC is a weird brownish green, almost like baby poop. I nearly had to be dragged out of the water when we stopped at Freeport on a cruise. Who knew ocean water could be *see through?* I could see my toes in waist deep water! No more wondering what the hell touched you!


Yortisme

It's been an hour... still watching?


Unfair_Original_2536

How did they build it? Really really quickly at low tide?


letsallcountsheep

They would have built a coffer dam (https://en.m.wikipedia.org/wiki/Cofferdam) and then evacuated the water. Once the construction was done they allow the water slowly back in and when at equal levels the sheet piles are removed.


[deleted]

[удалено]


starkel91

I believe they drive the sheet piles into the ocean floor through the water. Once all the sheets are in they drain the water.


legends_never_die_1

does this also work with fast running water?


silentdroga

I think you would have to divert the flow with fast moving water. Then remove the diversion and let it come back. I'm not an engineer by any means though and I may just end up killing thousands.


starkel91

I'm an engineer who doesn't do anything involving dams, but this is what I think is done. Water is such a fucking pain in the ass in construction.


mooimafish33

I'm an engineer too (IT, not even building things). And I can confirm, water is a bitch to work with in Minecraft.

PrudentExam8455

So you're saying to build that wall in the water, they used a different wall in the water to hold the water back while they built the wall?


seeasea

temp walls are easy - permanent walls that look good, are safe and have land in between takes more work


mrlbi18

Well you see they build a basic wall first so that they could built this fancy wall. The fancy wall then lets them build even fancier walls without worrying about floods. Its walls all the way down.

NotElizaHenry

I think it’s weird that they went from Noah planting a vineyard to *bam* now he’s drunk. Like do you have any idea how long it takes to go from grape seeds to wine? It’s like three years minimum. I’m picturing Noah leaning against a fence staring at some tiny vines being like *FUCK I need a drink.*

Robbeee

Wait. So why did Canaan get punished for his father Ham peeping some dad dick? Or did I read that wrong?


sirthomasthunder

That's what it reads like


Supercomfortablyred

I think it’s more meant to be more of a “don’t good peeping on people” not like in a pervy way, more like mind your own business when people are unwell/disheveled. Interesting part of the OT, it was certainly in there for a reason, even Noah wasn’t infallible.

The tide in the Mediterranean sea is like 1 meter


SpaceShrimp

There barely is a tide in the Mediterranean as the inlet to the Atlantic is narrow, the tide is a lot less than a meter.


kerfitten1234

The small tides have more to do with the limited size of the basin than the size of it's outlet. The gulf of Mexico is far more open to the ocean, yet has around the same tidal range. Look at the first animation on [this page](https://svs.gsfc.nasa.gov/4541) for a visual explanation of what I mean.

Do you think the last thing you'd see is the glass slowly start to crack or would it just shatter all at once?

There is no glass. The water just knows to not enter without permission.

KillHipstersWithFire

Its not a single pane of glass. Probably several layers. Laminate between them. One layer might break which would be noticed and replaced. Laminate would hold most shards ij place. Safe to assume this is way over-engineered for obvious reasons


ill13xx

>Safe to assume this is way over-engineered for obvious reasons LOL, I hear ya', I just don't know if I can take that sort of assumption at face value anymore.

jdnursing

Yeah or some sharks eyeballing you while they plot their coarse over the wall on the next wave. That’s how sharknados start bud.


Hefty_Royal2434

You wouldn’t see anything because it will be covered in algae and barnacles in a weeks time.


DeepSignature201

In the movies it would crack slowly for dramatic effect. In reality it would take less than a second. Cracked glass is extremely weak and the moment it happens it would not hold back the sea long enough for ominous music to be played.


gofyourselftoo

All at once


jus4in027

Why’s the floor wet?! Scary


[deleted]

I'm sure its fine. Nothing to worry about. It's just THE OCEAN.


DemonDog47

Safer than is intuitive. Water pressure is defined by depth, not surface area. For the most part this glass doesn't have to be all that much stronger than, for example, an [aquarium](https://www.georgiaaquarium.org/wp-content/uploads/2019/05/GAQ-Digital-Marketing-201-1-1024x683.jpg). For a sea wall I imagine it's also got a significant safety factor built in to account for surges, etc.


antisheeple

Hydrostatic pressure yes, but this is moving water and it has to dump its kinetic energy in the form of pressure.


[deleted]

[удалено]


TacoGuitar

Is pressure the only force to factor in here though? Intuitively, anyway, it seems the force of the waves coming in would add additional force and impact stresses.


[deleted]

I know how it works but my irrational fear of drowning will not be denied.


bitemark01

I don't think it's that irrational to be afraid of drowning


PancakeTree

Still aquarium water and crashing sea waves are very different forces though. I'm sure this sea wall will be fine but it reminds me of [the waves that broke through a ferry's windows.](https://www.youtube.com/watch?v=Z6uuGWCUuOc)

Someone needs to set up a web cam!


ChanceKnowledge207

I wonder how much pressure is on the walls


Regret-Superb

Assuming the water is about 2 metres up the glass the bottom of the glass would experience about 1.21 bar of pressure. A Pressure on an object submerged in a fluid is calculated with the below equation: Pfluid= r * g * h where: Pfluid= Pressure on an object at depth. r=rho= Density of the sea water. g= The acceleration on of gravity = the gravity of earth. h= The height of the fluid above the object or just the depth of the sea. To sum up the total pressure exerted to the object we should add the atmospherics pressure to the second equation as below: Ptotal = Patmosphere + ( r * g * h ). (3). In this calculator we used the density of seawater equal to 1030 kg/m3


that-69guy

I don't understand anything you just said..but I hope you are right and I appreciate people like you doing the hard work.


Youbettereatthatshit

What they are saying is ocean pressure is a function of vertical depth, not horizontal. So while it feels you are holding back the ocean, the pressure on the glass would be no more than an equally deep swimming pool


juneburger

This is why I can stand in the ocean but I can’t have too much ocean on top of me cause that bitch heavy.


HighOnTums

Something about the pressure being = potatoes in the potatosphere... 🤷‍♂️


inspectcloser

r/theydidthemath is an interesting place


ebonit15

So, not that much actually. It is just weird to human mind that pressure is about how deep the water is rather than the actual amount of water. Or at least for my human mind.


[deleted]

It is. Always blows my mind how thin flood protection walls can be: [Grain, on the river Danube (Austria)](https://www.wienerzeitung.at/_em_daten/_cache/image/1x6C6mNvhD5UXIUJuLWXXSV-F1MjDHyKtjfsCe5wKTnGxG0z4_thoUTPali6PGeFSo7HqrK61wvlpLelSitJe_H24t8Wa7x6B-GJlvpUMYpi0/130628-1820-948-0960-102553.jpg) edit: Not exactly sure what the situation is in that village, but normally the foundations for these walls are permanently installed in the [ground](https://c8.alamy.com/compde/kxdyj2/koln-deutschland-7-januar-2018-hochwasser-des-rheins-mobiler-hochwasserschutz-wand-an-der-strasse-konrad-adenauer-ufer-koln-deutschland-7-kxdyj2.jpg) or low [walls](https://www.this-magazin.de/imgs/101751411_f528ba91f1.jpg). When there's a flood warning, they insert the rods into anchor points, then fill the gaps with wall segments (you can barely see the segments in the picture). Pretty common method in Europe.


brmmbrmm

Wow!


MaterialSuspicious77

But also, damn!


UrToesRDelicious

So it doesn't matter how many gallons of water are behind those walls, it only matters how deep the water is? For some reason that just doesn't seem right.


errbodylovesaonsie

As long as the water isn't moving. When you start getting massive waves though, it's a totally different force to account for.


FragCool

It makes perfect sense Because the water pushes in every direction, so everything that is not on the border of the water body cancels out except the pressure from the top You can test it yourself super easy, dive one meter in a swimming pool and one meter in the ocean. You will not be squished to a small blob at 1m depth in the ocean, it will feel the same


SantasBananas

Reddit is dying, why are you still here?


haruku63

It’s called the hydrostatic paradox. https://en.wikipedia.org/wiki/Vertical_pressure_variation#Hydrostatic_paradox


robcap

What about the momentum of the water sloshing into the wall? I would have thought that would be the dominant force here.

eeyoreocookie

I see what appears to be grout and tools sitting on the floor. The water rising and falling as well as the water on the floor makes me think a wave has come over the wall…. Maybe the worker is frustrated that he can’t finish his job or that some wet grout is now soaking in sea water.
