Assuming a massive nuclear exchange between NATO and Russia plus China and India and the destruction of pretty much all the major cities of the world and resulting EOTWAWKI scenario, how long would dams last after humanity reverts to medieval technology?

Specifically, earthfill dams like this one.

Would the locals be able to maintain the dam indefinitely with a dark ages level of technology, or would it just degrade over time and eventually fail after a few decades or centuries?

is this a god dam?

In what fantasy world does a full exchange of nuclear arms are you proposing? Real life isnt fallout
>>
>>29110894
No, it's an earthfill dam.
>>
It's just a dam. It's probably going to be fixed in place with no power but it'd just be repaired when power is restored.

People don't just suddenly forget how to make things.
>>
>>29110950
You're grossly underestimating the reliance people have on the internet these days.

Considering that most manufacturing and people trained in manufacturing live in the cities that would be vaporized during the exchange and the survivors in rural areas don't really have access to the information needed to keep society functioning at its current level, we'd be back in the dark ages before the fires in the cities burned themselves out.
>>
>>29110984
No, I'm not, I'm just not buying into your video game fantasy land where the only people that survive also happen to be the only people who never did STEM education.
>>
>>29110877
Stop it with this nukes will destroy the world stuff. A full on exchange wouldn't put us back to the dark ages.

You might be grossly overestimating the reliance on major cities. Cities are very important hubs, but to assume the United States would turn into (detroit? Wild west?) If Mew York and Atlanta and Los Angeles gets obliterated is a bold call. I'm assuming a lt of other cities would still exist? Shit like White Plains NY and cities that size. If thy all get wioed out too then well shit, yeah the world is gonna hurt because a lot of rural areas already have less shit available to them than big cities and nukes haven't even gone off yet.

Perhaps we'll see what happens sooner than you think.

The people in rural areas who have education in the STEM fields are pretty irrelevant. When the cities disappear, so do internet, telephone, and television. So does electricity production. So does oil refining. Natural gas is gone too.

Local gas and LPG supplies will only last for a few weeks at best. Sure, maybe some smart guys would be able to set up small scale refineries in bumfuck nowhere, but it won't be enough to keep society going.

Even if we assume that the pumpjacks keep running and wind farms keep producing electricity, eventually they'll break down due to lack of maintenance and inability to manufacture new parts.

As years pass, more and more of the things we take for granted today will cease to exist. Guns will stop being a thing in a few decades or maybe a hundred years as ammunition supplies dwindle. Horses will replace cars within a year or two. Heating will return to wood burning stoves and fireplaces within weeks. Running water will stop being a thing almost immediately and people will have to go back to digging communal wells by hand or resettle near rivers and lakes.

It won't all happen immediately, but technology would quickly slide back to pre-industrial levels and then eventually back to pre-renaissance levels as time passes and the people who grew up in the times before the end of the world get old and die off.

>The dam, Iraq's largest has suffered from structural flaws since its completion in 1984, with the water constantly eating away at the soluble gypsum base on which it is built

Interesting but one main reason for the quick deterioration of that damn is because it was shit to begin with and what it's made of. 1st world dams may not have that same exact problem.
>>
>>29111100
You're assuming so much that happens to be built around how you WANT it to be, it's absurd.

Come back from la la land.

You really have no idea huh. You're adamant that your fantasy world will come true.

People in fucking Nigeria make gas at illegal home-made refineries.
>>
It really all depends on weather up stream of the dam.

If heavy flood waters happen and lots of water and debris get washed into the dam. Then you will probably get a severely damaged or failed dam.
>>
>>29111158

Holy shit it's illegal for them to make gas?

And America isn't liberating them...?

Americans can't even liberate themselves... Florida made solar panels illegal.
>>
>>29111226
Making gas in your yard, isn't something that normal people do and it likely creates a lot of dangerous chemicals that need to be disposed of properly to prevent costly clean up and pollution.
>>
>>29110984
You're grossly overestimating the number of nukes available to all parties, plus it sounds like you're grossly overestimating the amount of damage a nuke does, and , finally, you're completely ignorant of the real-world realities that drive nuke use policy. You really need to lurk some Oppenheimer threads, maybe ask him for a reading list.

A total nuclear exchange would probably knock us back to somewhere around 1940s tech. They knew how to build and maintain dams in the 40s. For that matter, earthfill dams date back to around 3000 BC. It's not high tech, anon.
>>
>>29111804

As opposed to large scale industry which is heavily regulated but still improperly disposes chemicals and creates insane amounts of pollution....?

Being worried about individuals is kinda fucked up especially considering how much government approved organizations have fucked the planet.
>>
>>29111132
Yeah, it sounds like we got one of the hard-shelled ones here. It's like he figures that every library and high school science lab in the country will burn in the atomic fire of billions and billions of nuculer warheads all going off at once.
>>
>>29111100
By that logic, when the black death wiped out 60 to 75 percent of europe they should have slid back into the bronze age.
(And it DID wipe out the top echelons of society worse than it did average joes bdcause the priests were the cultures repository of learning and caught it from parishoners as they administered last rights and tried to treat it.)

And what happened? Shit sucked for 100 years and then people invented scientific procedure and the renaissance happened.
Catastrophies arent time machines. Entire regions would remain untouched, or, would get dusted with fallout and have to wait 3 to 4 weeks to start recovering, if that.

Will we have cell phones and TV? No, but people dont become retards just because society gets dickpunched.

Quit reading scifi and start reading history. Humanity has been almost wiped out multiple times, its is inevitably followed by a breeding boom and a surge in devdlopment, because as soon as there is a generation that can't remember why everyone is in a survival/nessecity only state they start trying to find ways to be comfortable again.

When rome fell things backslid a bit. In EUROPE. Asia was just fine, in fact, they were busy inventing printing presses and gunpowder.

Bits of humanity get fucked, but as a whole race we have never stopped progressing.
>>
>>29112155
And entire countries would be left untouched.
It would be funny to see some place like venezuela or australia become the next world superpower over the following century.

That guys entire fantasy revolves around the false concept that humanity revolves around america, china, and russia.
>>
>>29110877

Depends if the dam itself is nuked. You have more to worry from flooding or radiation then EM damage. For example, California in a nuclear war will get fucked over by massive wildfires (most not spawned directly from nukes, but from careless civilians) and flooding (due to levees near inland targets being broken).

>>29110984

most people live outside cities, in suburbs. Furthermore the people that matter (middle class engineers, doctors etc) tend to live away from noisy downtown and industrial areas (aka, targets)

At any rate, the most damage comes from people panicing and not being prepared. Ever wonder why the government put so much effort into CD stuff? Because it pays. The only thing scarier then a nuclear war is 1,000,000 scared people endangering each other.

Which cities have oil and natural gas refineries and all the major power plants right at the city centres?

Initial fear and unrest would be bad, but I see no reason why this region would fall back to anything earlier than 1900's era level of sophistication. Theres plenty of workers from all these places and industries, and nothing stopping them from profiting off of this and teaching thier children to do so as well.

>how long would dams last
Returning to topic: the dams themselves could last centuries. Old Roman structures remain after more than 2000 years.

However the dams would possibly be rendered useless in about 30 years since silt builds up behind the dams. This is a huge problem for Three Gorges in China. Without a lot of maintenance the power production would tail off and end in a few decades.

Also turbines and generators need a lot of care.

Florida made it illegal to place solar panels on residential rooftops cause muh childuns or something like that.
Corporate solar panels and solar farms are still legal and probably even encouraged with tax breaks or similar rewards

Are you 14? "hurr durr you forget all the smart people and industry is in jew york city. So nukes would make us go medieval". Have you ever even lived in the city or any major city? All you'll find there is bankers, students, and trash. They import everything, even their construction crews are mostly from out of state. I know cause I used to work on one years ago. Also you assume that everyone is able to launch and hit their targets with 100% success to even hope on collapsing a country.

I live in Florida.
This is bullshit. There's at least 20 houses in my neighborhood with them on the roof. You get tax incentives for doing it, too.

people seem to forget that almost any small-medium town has a public library, which contains volumes upon volumes of technical documentation on all sorts of shit, up to and beyond theoretical stuff. Sure, not every library will have every book, but the sheer volume and dispersion of knowledge creates essentially a "vault" of knowledge for humanity that has never existed at any other point in history.

>but books will molder and rot
yeah and people will fucking hand copy them if they have to. You could probably jerry-rig a shitty type set printing press based on how you think it's supposed to work, with very little tools.

on top of all that knowledge is the shit ready-made and sitting in state. Sure on a long enough timeline buildings will collapse and stuff, but survivors of any catastrophe will realize that as soon as the basic survival is taken care of, restarting and rebuilding is the top priority.

Libraries man, savior of the species right there.

>You could probably jerry-rig a shitty type set printing press based on how you think it's supposed to work, with very little tools
of course you could
At the very worst we'd temporarily eschew complex electronics in favour of pre-transistor stuff that's easier to maintain with a low-skilled workforce but in the long run it'd be a speedbump. Massive population reductions have happened many times in the past. While they're incredibly shit at the time, a short while afterwards things normalise and if anything great opportunities exist for those that survived. Look at the black death, it massively expanded the middle classes and ended feudalism

>>29117968
I think what he meant to say that it's illegal for people who rent apartments to install solar panels. Pretty sure homeowners can do whatever they want.
>>
>>29119090
isn't that pretty much a pointless law? It's the landlord's roof anyway
