The French tried it that way and failed. About 1/4 of the canal is ditch and the rest is locks


tabovilla

Actually, a lot more is ditch. But for me, the really clever part was figuring out that building some strategically positioned dams would start to contain rain/river water, high up in the middle of the central cordillera, to allow the creation of the largest artificial lake at the time, and eventually having ships sail through the once dry and irregular mountain system. Mind blown.


Demi_Bob

It seems like the kind of fever dream idea you have that you work on for fun for a while until it starts to seem almost realistic and then you present it to management starting with "now hear me out..." And ending with "you're fucking fired."

John Houbolt at NASA comes to mind. Suggested rendezvous in lunar orbit to solve the rocket mass problem when nobody knew how to make two spacecraft meet in orbit, even around Earth. https://www.npr.org/2019/07/18/739934923/meet-john-houbolt-he-figured-out-how-to-go-to-the-moon-but-few-were-listening


stvangel

Best thing they ever did was Gemini so they could figure all this crap out beforehand. And it was on the cheap.


cyrusm

Yup That was the whole point of the Gemini missions. Take twin ships and put them together just to see if we could. The first attempt actually failed because they didn't understand orbital mechanics well enough. They kept burning towards the target, but the target just kept getting farther away. They didn't realize that to speed up they actually had to slow down to lower the altitude to increase speed.

You only got fired because you didn't mention the part about everyone catching malaria.


Phormitago

engineering can get rather silly when you have carte blanche to destroy whatever nature is inbetween


xenapan

If that were the case I think the engineering would be way simpler to just blow up the whole landmass and let it fill with water so ships can sail right through. Would be a much simpler solution than multiple locks and pumps that need to be constantly maintained and operated.


CalderaX

They thought of it. Came to the conclusion any sane person would come to: it's a fucking stupid idea


NinjaLion

More info on FUCK DIGGING LETS JUST USE NUKES [here.](https://www.forbes.com/sites/robinandrews/2018/08/23/this-is-how-america-nearly-nuked-a-canal-through-central-america/?sh=77523cf3d74b) highlight: > A 1970 report, spearheaded by the respected Corps of Engineers brigadier general Charles Noble, advised against the plan, noting that it was not economically viable, and would endanger both the environment and various indigenous populations. notice that economic viability came first, then they mentioned the murder and radiation. god bless the 1960's


CalderaX

What a time to be alive


xenapan

Not really. They do the opposite all the time. Land reclamation from the sea. And that's harder to do since the tides will drag material out, the risk of sinking etc. So please elaborate what makes digging/blowing up such a terribly stupid idea?


CalderaX

Mate i'm pretty sure that if you think a bit longer about why it might be a bad idea to try to blow up an like 90 km long stretch of land mass - with a max elevation of i think 30 m - to goddamn sea level (or as you put it so nicely "the whole landmass and let it fill with water") with conventional explosives. If you're thinking nukes, thats even worse. SO much worse. Also you didnt say anything about digging, but on that point we dont even have to argue: they tried it in panama. They failed horribly. They never tried again


CalderaX

Hint: during ww2 (when you think explosives production would peak) an estimated 3 Mt of bombs were used in the european theatre. Thats bomb weight, not explosives weight. For the construction of the panama canal as it was back then they used 30 Mt.


formgry

https://en.wikipedia.org/wiki/Qattara_Depression_Project Maybe you'd be interested in this thing. The Qattara depression is area in the sahara below sea level and relatively close to the mediterreanan sea. Since the early 20th century there has been the idea of blasting a canal between the sea and the depression creating a massive artificial lake that could generate hydroelectricty. Digging the canal normally would have been too expensive though. So instead the proposal was to use a lot of nuclear explosions to blast a way through the rock. Just such a proposal like you're thinking off in your comment. Nuclear explosions was too concerning a solution though. The article mentions 25,000 evacuees, dangerously effecting the nearby tectonically unstable red sea rift, and increased sea erosion due to changing sea currents. I'm assuming there's more drawbacks though because these 3 seem relatively mild for a plan that involves detonating more than 200 nuclear explosions.


Seawolfe665

I was on a cargo ship going through the canal and chatting with the pilot - and I was astounded to hear that there are effectively NO pumps to the canal. The rainfall is SO heavy that it's really all just water flowing downhill, with raceways to the side to let the extra water go if needed. That really blew my mind.


tortoise53

Is that lake gatun? I went fishing there a few years ago and it’s quite impressive.


ramonvls926

Lake gatun stretches all the way through there. Fun fact, we had an infestation of fish in lake gatun (some type of fish dont remember which one) and they brought over some version of crows that ate them, now that wasnt controlled so we have an infestation of weak ass crows we call "talingo".


tortoise53

Haha always so interesting to see the downstream effects when we introduce a new predator to get rid of an existing pest.

ReditUsername876

Why isn't it a canal?


actuallyserious650

Too much earth to move. Easier to go over than through.


DHFranklin

That's the Suez. The elevation between the Mediterranean and Red sea, and the Sinai desert doesn't change much.


marinmarge

Yea me too, now it's even more interesting


57hz

Been through it, can confirm - one big ass ditch. What’s really amazing is that some of the lock doors are original, over 100 years old! Still working as designed even though in contact with air and water every single day.


KIDNEYST0NEZ

I wonder how that would work with the curvature of the earth?


alaskafish

The same way the ocean does


KIDNEYST0NEZ

Wow I didn’t think a question would invoke so many downvotes.


Derbla-99

They probably thought you were a flat earther or something lol


jager000

I think people thought you were starting a flat earth argument


KIDNEYST0NEZ

Nah because in another comment about the exact same situation someone said it would cause ecological issue with the oceans colliding and competing, I said why not use the electrical barrier such as the one in Chicago and that got even more downvotes and it was all hypothetical. I think maybe the topic of canals, oceans, and earth may be more sensitive than expected.


dontmentiontrousers

Honestly, it a really weird Reddit thing to get downvoted for asking *any* question. *Thou shalt not seek further information to progress the conversation.* Quite often see people apologising and / or explaining why they're asking a question before asking it, presumably to avoid that. So weird.


KIDNEYST0NEZ

Well I’m not apologizing for asking a question!


dontmentiontrousers

I'm with you, brother (or sister or sibling). More level heads usually prevail and the votes start going the other way. Can't say I'm too bothered about the karma, but it's a strange reflection on how people think.


KIDNEYST0NEZ

My issue is I’m on one forum where people are mentally designing and tweaking a design for a homemade railroad cart to simplify the forward and reverse system and we have a whole entire thread doing it. This one the questions are buried lol


ooo-f

Yeah idk why either, you were just asking a genuine question. Reddit has been super hivemind-y about downvoting comments like yours into oblivion lately. I gave you an upvote to counteract it.


KIDNEYST0NEZ

So do you think one ocean is higher then the other? My main question is that do you do a specific depth from one ocean to another or is there a major elevation difference?


redisurfer

All oceans are connected so if one was higher in one it would drain into the others to balance out. That is of course not taking the moon into account which causes the ocean to swell towards itself, same for the sun though less so. TLDR: whichever ocean the moon is current over is higher than the others, otherwise they’re more or less level.


crypticedge

The pacific ocean is always higher than the Atlantic at the Panama canal, by 26 meters. https://www.marineinsight.com/guidelines/how-the-water-locks-of-panama-canal-work/


Justice_For_Ned

I read your article (which was really cool by the way), but I didn’t see where anything said the Pacific is higher than the Atlantic. Ships are raised 26 meters at the first locks on the Atlantic side, but they’re lowered when the reach the Pacific side. Still, it was fun to read about the Panama canal so thanks for the link!


[deleted]

[удалено]


redisurfer

That article says the ships have to be raised 26m to get over the Panama terrain, not because one ocean is significantly lower than the other. I totally get the confusion but careful spreading misinformation, that’s how we get flat-earthers. 😜


KIDNEYST0NEZ

Wow that is significant!


[deleted]

[удалено]


sankafan

LOL no, sir. The depth of any body of water on Earth is negligible compared to the radius of the planet. Sea level is about 20 cm higher on average on the Pacific side than the Atlantic due to the water being less dense on the Pacific side, on average, and due to the prevailing weather and ocean conditions. Such sea level differences are common across many short sections of land dividing ocean basins.


KIDNEYST0NEZ

So in this instant would a ditch from one ocean to the other mean the passage would have tides.


No-Patient

Tide occurs in almost all places. As tide increases in one area, its decreasing in another, and water would need to travel through any available passage that gravity allowed for. If the ditch allowed for the difference in water pressure to pass all the way through, then tides would force water in or out during the change. The problem with the curvature of the earth and digging a ditch is simply that you have to dig deeper at the highest elevation points, in order to keep your water level. At some points in Panama, this could be several hundred meters.


KIDNEYST0NEZ

Nothing a little terraforming can’t handle, I appreciate the input thank you!


ooo-f

Bruh why did you downvote me lmfao I legit just upvoted you because you were asking a question. Idk why you're coming at me


KIDNEYST0NEZ

ooo-f

Weird. Idk what's going on with reddit lately.

It's just votes. Sometimes they go up sometimes they go down. That's the way things are, and I wouldn't interpret it as a personal attack on your comment. Since it's never nice to see yourself being personally attacked.

I grew up near Falkirk; my fav fact about the wheel: this one-of-a-kind giant takes only the power of boiling 8 kettles in order to move 100s of tonnes of boat and water, thanks to the Archimedes principle. Perfectly balanced - as all boats should be.

j0akime

Let Norway figure out what needs to be done for a large ship tunnel first. https://en.wikipedia.org/wiki/Stad_Ship_Tunnel TL;DR; - Norway is building a tunnel between 2 fjords big enough for a large cruise ship to pass through.


TheBelhade

I thought that said "sad ship tunnel" wahh-wahh


FallingVirtue

Haha nice only took them 147 years (since the first proposal) to settle on a plan. One included putting the boats on carriages and just wheeling them overland. Giant hole seems better and is going to be an amazing feat of engineering.

I believe the UK press started calling the Channel Tunnel exactly this while it was news.


IveBangedYoreMom

I really wonder what would happen if they were able to dig straight through. Would it just be a rushing torrent of water/river? Edit: I know there is an elevation difference (which is a little perplexing) but that is the point. Hypothetically, if you could dig a trench, would it be just a constant waterfall/river.


theservman

The initially wanted to build it as a sea-level canal, like the Suez, but the elevation differences were too much.


nrith

Just cut it through with no locks and let the higher side drain into the lower side until they’re equal. Duh. /s


IveBangedYoreMom

Right. Which is why I was wondering, hypothetically, if it would just be a torrent flow of water

NoiceOne

Understood, understood. But like, hear me out, *hypothetically* would it be just a torrent flow of water or what?


cantlurkanymore

I dno, ask the rock of gibraltar


Yvaelle

The tides of both oceans are not synced so you would have directional flow yes. Mean sea level on both sides is \~equal though. Caribbean tide is tiny, Pacific side is big - so the Pacific is either going to suck or spit water into the canal. A good example is the Suez Canal which is just a big flat passage through -and it's mostly not an issue until the current, the cross-breeze, and the boredom of it conspire to make a tanker wedge itself into both walls.


MinimumFlatworm

well, ecologically it’d be a disaster. Not only the ecossystems of both oceans would start competing, but it could ruin the forest adjacent to the canal.


KIDNEYST0NEZ

It would balance out that and if not there could be an electrical grid installed in one section to prevent the two ecosystems colliding.


Runnerup3679

Bro. Ain’t it crazy how all you did was throw out a hypothesis to the presented problem, and for no other reason than that have been downvoted 13 times lol. Reddit is so fickle.


KIDNEYST0NEZ

This thread alone has cost me about 300 downvotes, but interestingly enough the electric barrier idea came from a Chicago Sanitary and Ship Canal located in Romeoville Chicago. It has prevented an invasive species from wiping out a local fish population and is actually pretty successful!


very_humble

They can vary by 20' in height so that would never work


IveBangedYoreMom

Well, I know, but hypothetically. And the height difference would create the rush of water


QueryThePlatypus

Water from underground would keep it flooded at all times

Shino_42

Can someone explain why can't it just have 1 water elevators on each side?


CoffeeBox

The panama canal is 40 miles long and the elevation change is 85 feet. [Link](https://www.google.com/search?q=panama+canal+length&client=ms-android-verizon&prmd=imnv&sxsrf=ALeKk0378DUceV-_R7VfkGf1kQ9ZSPC-hQ:1622726645825&source=lnms&tbm=isch&sa=X&ved=2ahUKEwi3w6rqx_vwAhUWWs0KHUVECFgQ_AUoAXoECAIQAQ&biw=360&bih=651&dpr=3#imgrc=F8dwRH64yETQfM) A 20 mile long, 85 foot deep water elevator would contain 3.65 kilo-fucktons of water. That water elevator would take forever to fill and drain. The doors required to hold that much water from flooding into the ocean would resemble the Hoover Dam. Excuse me, the Hoover dam on giant ass hinges.


slowest_hour

so it's like looking at stairs and asking "Why have many stairs when you could just take one really big step?"


tabovilla

The middle lake (Gatun) is too high to be able to build a single lock between sea level and lake surface. Lock doors would've had to be 150ft-200ft tall or something absurdly big. It would take ages to fill one single chamber whilst only rising one ship at a time, and the water wasted would drain the lake faster than yearly rain/storms are able to refill it. Having a stepped design allows a constant pipeline of ships going up or down quickly, in sequence, while saving water from the lake.


MrMuf

Alot of digging. Probably some Ecological concerns, etc.


GraceaholicsAnon

How long does this take to get through?


jnnyfrmthblk

I was wondering the same and looked it up ... [pancanal.com FAQ](https://www.pancanal.com/eng/general/canal-faqs/) says: "The length of the Panama Canal is 80 kilometers (50 miles) from the deep waters of the Atlantic to the deep waters of the Pacific. A ship takes an average of 8 to 10 hours to transit the Panama Canal."


Oscuro87

I would have guessed more! Ty for the info


enjuisbiggay

That sounds like a pain in the ass


MetalGearObama

enjuisbiggay

ottterbot

yea lets just go around cape horn instead. saves us the trouble


shapte

a lot of huge ships actually do that, since they're too big to fit through the locks — including cruise ships.


enjuisbiggay

See this is why redditors are the smartest people on the planet /s


[deleted]

I thought the ships are pulled up by big fish, One Piece style you know.


RapidWaffle

For those asking why didn't they just dig a ditch. Have you tried blowing up a mountainous terrain down to sea level? Yeah, locks are easier


millerlife777

Wait are the seas the same level. Wait, is there only one sea level. Omg wtf I going on...


giving-ladies-rabies

There isn't only one sea level. There are many things to consider here: - The Earth is spinning, so centrifugal force will cause more water around the equator compared to poles - There are ocean currents forcing water into certain areas - The water will be affected by weather, winds, precipitation, evaporation - Water has different density based on its temperature There's probably more, I am no expert. But yeah, if you cut through the canal and didn't have locks, the water would come rushing from one side to the other, even though it's technically the same body of water. It's weird to imagine on our everyday scale.


millerlife777

Hmm for some reason people make it sound like there is only one sea level. Like when we reference the hight of a mountain or altitude. Maybe it's just an average?


stairme

Correct. MSL = mean sea level. Altitudes are measured in MSL i.e. height above average sea level.


Malfunkdung

Pretty sure it’s just average. If you’ve ever lived near the ocean, you sort of instinctively know the there’s no “sea level” considering the tides move up and down (in some extreme cases up to 50 feet).


slowest_hour

So saying "sea level" isn't a constant, it just means "whatever the sea level is closest to here right now" Kinda like how people say "The speed of sound" when what they mean is "the speed of sound in earth's atmosphere at this level of humidity and temperature"


MarshallGibsonLP

Whenever you hear the term sea level, you’re really hearing a truncated term that is actually mean sea level. You’ll even see elevations expressed in “MSL” which factors in changes in tide, etc. in that respect it is a constant.


theodocles

But then wouldn't all the water in the ocean end up on the right side? Checkmate, science. /s


notacanuckskibum

The system relies on rainfall to continuously refill the lake at the top. There are concerns that climate change might break this.


theodocles

As soon as I saw "relies" and "rainfall" in the same sentence my brain immediately went "this thing is fucked"


busdriverbuddha2

Then we just wait for the rising sea levels to cover Panama. Problem solved /s


trimeta

Actually, all the water comes from the lake in the middle. When going towards the lake, water from the lake is used to pour into the lock you're currently in, to raise it up. And when going away from the lake, water in the lock is dumped into the ocean you're headed to, to lower the lock. This is clever in two ways. First of all, there are no pumps carrying water uphill: water only ever flows down, from the lake. Secondly, this significantly reduces mixing of water from the oceans,


hsvsunshyn

For anyone wanting more information about how the locks ("water elevators") work, Practical Engineering has a good video: [https://www.youtube.com/watch?v=SBvclVcesEE](https://www.youtube.com/watch?v=SBvclVcesEE) (If you do not want the history and other information, skip forward to about 2:40 for a demo of the locks.)

Bladek4

micro_rich

That’s some fuel saving!what kind of toll charges apply?


Bladek4

Depends on the type of ship, the size, what is being carried, how much of it, and the country the ship is from. You could pay a couple hundred in a small boat but most containers (panamax) pay around a couple hundred thousand. The post panamax ships on the new set of locks pay almost a million per crossing. They still save a lot of money though, given they save on fuel, time, insurance, work force, etc. (I used to work at the canal as a tour guide, I used to explain this to tourists everyday lol) Edit: I am talking in USD.


micro_rich

Really appreciate your info, a million per trip jeez that’s shocked me, thank you 👍🏻

I'm sure whoever is in charge of pricing just calculates the risk of sailing around Cape Horn (long trip, very dangerous) and then subtracts a buck.

Depends on the canal pilots. You can also pay more to be prioritized. First time it took us about 36 hours. Second time it was 72, but that’s because of other reasons.

Why does the water level in the higher levels drop when you are on the right side of the canal, but not when they're filling in the left sides?

anomander_galt

Why couldn't they "cut" panama like suez without all these steps?


HumblerSloth

Local altitude. There’s a lot more land mass and altitude in Panama. Egypt is relatively flat and close to sea level around the Suez.


readparse

This is not entirely right. The water levels on the left side should be showing equalization between each lock at the lock above it, as it being shown on the right side. This illustration is correctly showing that water always flows from a higher lock to a lower lock, also from the lowest lock to the ocean, and from the lake to the highest lock. It also correctly shows the water finding its own level on the right, but it fails to show this on the left.


sunshinelovin2000

My husband operates a local lock. Its really amazing watching. They're digging a newer bigger one at his lock and thats also cool to see the progress and how its done

Roxas_0

No! You go around the horn the way God intended!


StairheidCritic

HumblerSloth

But the fuel costs are higher than the canal fees. Or the added time around the horn makes the canal viable.


RapidWaffle

To be fair going around the horn, it's a few thousand extra kilometers, a few extra weeks a lot of extra fuel and going through one of the most dangerous waterways in the world
