The Nova Kakhovka Hydroelectric dam in Ukraine has been blown open
- dsab 3y agoIts yet another russian war crime during Ukraine invasion
- 2-718-281-828 3y agohow? if it's a war then isn't it legitimate to destroy energy sources?
- dralley 3y agoNot by flooding tens of thousands of people out of their homes and wrecking the local ecology
- esarbe 3y agoDestroying dams is explicitly a war crime.
- 2-718-281-828 3y agowanted to take you up on the "explicitly" then just googled it myself. in deed the additional protocol i of the geneva convention has something explicit to say about dams. ---- "[...] the Nova Kakhovka dam has been earmarked as a potential target for [...] its strategic importance" "Its destruction would have a number of significant repercussions [...] for Ukraine’s wider war effort." https://www.theguardian.com/world/2023/jun/06/nova-kakhovka-dam-everything-you-need-to-know-about-ukraines-strategically-important-reservoir https://www.theguardian.com/world/2023/jun/06/nova-kakhovka-... -- "2. The special protection against attack provided for in paragraph 1 shall cease: (a) for a dam or a dyke only if it is used for other than its normal function and in regular, significant and direct support of military operations and if such attack is the only feasible way to terminate such support;" https://ihl-databases.icrc.org/en/customary-ihl/v2/rule42 https://ihl-databases.icrc.org/en/customary-ihl/v2/rule42 ---- don't know whether or not this constraint applies. i'm anyway not really intending to justify this or russia's attack on ukraine in general. just don't like pointing out cruelty in wars as if it's a surprise this is happening. war is about killing more soldiers than your opponent and there never was a war not impacting civilians. many people seem to think: "i'm against war except if it's fought fair and without killing children, elderly, women, handicapped people and civilians in general."
- esarbe 3y agoI don't think that this constrain applies. The dam was part of the Russia-occupied territory or part of the gray zone. Ukraine was not using the damn dam for anything. At this point I'm not willing to give Russia the benefit of the doubt anymore. Their leadership has more than sufficiently demonstrated that they consider atrocities and crimes of war as part of the toolbox, so to say.
- 2-718-281-828 3y agodoesn't this make it more plausible that ukraine blew it up?
- esarbe 3y agoThe dam was under Russian control. Ukraine wouldn't have had any opportunity to place demolition charges. Russia has demonstrated that it is; - willing to level cities with hundreds of thousands of inhabitants - willing to use torture, abduction, rape as systematic weapons of war - willing to indiscriminately attack civilians - willing to use banned weapons of war Despite war crimes obviously (d'oh) happening on both sides of the conflict, the Russian leadership has made it evidently clear that is more than happy to unleash any amount of terror, pain, misery and suffering to get what it wants. The Russian leadership is perfectly a-ok to systematically use all of the aforementioned as weapons. I've not seen this callousness from the Ukrainian leadership.

- TeMPOraL 3y agoInteresting follow-up by the same poster here, quoting WaPo tweeting some Maxar photos, showing that the dam seems to have suffered some damage in the past week - adding credence to the possibility that it did, in fact, "collapsed due to damage", without either side specifically pulling the trigger today. https://twitter.com/AricToler/status/1665937030222692352 https://twitter.com/AricToler/status/1665937030222692352 But that brings up the question, what was happening there in the week prior?

- baybal2 3y agoNo, it's a scorched earth tactic, in preparation to abandoning Crimea. Without this dam, Crimea will be without water for at least next 3 to 5 years after Ukraine recaptures it.
- UberFly 3y agoThis is actually correct, at least the effect it will have on Crimea's water supply.
- wolverine876 3y agoIf you have a credible source that goes into detail on that, I'd appreciate it.
- mantas 3y agoThere's no significant drinking water source in Crimea. And this was the dam directing water to Crimean water channel. Not sure what other credible source you may want.
- dmix 3y agoThe next question is how long would it take to repair if it does slow down / reroute the counter offensive? There's lots of evidence it harms Russian troop build ups in the region but only if they plan on abandoning the southern Kherson region and don't have any plans beyond that.
- wolverine876 3y ago> Not sure what other credible source you may want. I'm a little confused: You did not provide any source. You're not obligated to provide any, but I don't understand your comment.

- skjoldr 3y agoVladimir Vladimirovich is going to be remembered as the next Adolf Stalin and for a good reason. Post-1945 world is not magically immune to the emergence of such people in power. Grey morality, especially with regards to genocidal dictators, is a myth that the West fell into because Germany had to be quickly whitewashed into being a NATO ally. Hence the "clean Wehrmacht" myth, the Rommel myth, and more. Now this cognitive distortion plays out with regards to Russia and their crimes, "oh they can't be completely evil, nobody can be completely evil anymore", when that is just a myth. Sometimes we can see the same distortion with regards to China, too.

- wolverine876 3y agoInteresting, thanks, though only one incident. Do you know any sources on Russian military strategy?
- deanCommie 3y agoI'm not a military expert, but it seems like this will benefit the Russians, who will now have time to reinforce and strengthen their positions in Kherson Oblast on the south side of the Dnipro River at a time when Ukraine has been gaining momentum, and possibly considering crossing for a counter-offensive. From a purely positional perspective, this is a big advantage for the Russians, who benefit from a more prolonged conflict because they have more people, and need more time to resupply their logistics. Not great.
- somedude895 3y agoI'm not sure Ukraine ever planned a large-scale crossing of the Dnipro from Kherson. Certainly not for the main thrust of the counter offensive.
- The_Colonel 3y agoUkraine needed to present a credible threat to cross there to pin Russian forces in the area. Now that it's basically impossible to cross the river, Russia can redeploy the majority of the forces to other areas.
- somedude895 3y agoWas it ever feasible for them to cross the Dnipro with heavy equipment though? It already seemed too wide for pontoon bridges?
- The_Colonel 3y agoLast fall, Russians have built and used several pontoon bridges over Dnipro for a few weeks, as they defended Kherson city and the Antonovskij bridge was rendered unusuable by HIMARS strikes.

- bjoli 3y agoSomeone provided confirmed russian defensive positions along Dniepr. Unless the Russians moved out before the Ukrainians would have at least a reason to destroy the dam. They have, however, avoided civilian casualties, and looking at the map this would have been a deviation from that. It would fit the russian MO better
- jononor 3y agoWhat are you saying could be a reason for Ukraine to do this? The flooding is probably not fast enough to trap/kill soldiers at those positions. And while those defensive positions will be "destroyed", they are replaced kilometers of marshlands, which is a superior defense, at least in the coming months. It can be held with much fewer people, shortening the effective length of the front, and freeing up soldiers to be used elsewhere. Massive gain for Russia, unfortunately. Likely nothing positive for Ukraine, unless they have something _incredibly_ creative going on.

- perihelions 3y agoLooks historically unprecedented (?). This is a run-of-the-river type dam (relatively small elevation drop between upstream and downstream), but one with an enormous reservoir, with a volume (1.8e10 m³ nominal) larger than e.g. Banqiao (4.9e8 m³) or Mosul (1.1e10 m³).

- psychphysic 3y agoDid Ukraine just wipe out majority of Russian defences? That could go down in history as one of the boldest moves ever.
- Scarblac 3y agoRussia was in control of the dam, had mined it, and had in recent weeks let water levels go up to unprecedented levels. Something like 80 settlements will be completely inundated, the largest nuclear power plant in Europe loses its cooling reservoir and attacks over the river will be impossible for weeks. I don't think Ukraine did it. (getting information from the thread in /r/worldnews).
- psychphysic 3y agoIf it wiped away defences it'd be more than worth it and Ukraine is now more than capable with its Shadow Storm missiles which UK provided just for this kind of attack. It's a very bold move and if intentional it could be pivotal in this conflict.
- dralley 3y agoIt doesn't matter if the defenses are wiped out, if you cannot cross to reach those defenses. The terrain and roads will be wrecked and everything will be a muddy mess for miles.
- psychphysic 3y agoWhoever knew this would happen (i.e. planned it) stands to gain massively in strategic terms. That's the case no matter if it was Russia or Ukraine so long as it went to plan.
- sgc 3y agoIt is an act of mass destruction and a war crime, that Ukraine was very worried about for some time since it will kill many innocent people. Very, very unlikely they did it. My first bet would be the dam failed from russian negligence / mismanagement, second the russians blew it up. But there will certainly be video of what happened today soon.

- perihelions 3y agoOf course it's totally unsafe: it's in a war zone. It's on the current, active front line of a warzone. If this dam collapse doesn't cause a catastrophic spent fuel nuclear disaster in the next few hours, there's still imminent danger of that from any number of different causes – most visibly, military actions occurring right next to (or inside of!) the power plant. The IAEA messaging has been extremely shrill about this for like a continuous year, and no one listens. e.g. - "After nearly nine months of failed efforts to forge an agreement between Ukraine and Russia to establish a protection zone around the Zaporizhzhia nuclear power plant (ZNPP), Rafael Mariano Grossi, the head of the International Atomic Energy Agency, is now pushing for a new proposal to reduce the possibility of a catastrophic nuclear disaster." https://www.washingtonpost.com/world/2023/05/22/ukraine-zaporizhzhia-nuclear-plant-grossi/ https://www.washingtonpost.com/world/2023/05/22/ukraine-zapo...

- wiseowise 3y agohttps://t.me/jurnko/7938 https://t.me/jurnko/7938 [Ukrainian language] Here’s a post from Kherson journalist with breakdown of Russian propagandist reactions to the situation for those who still think it’s not Russian orchestrated explosion.
- cwillu 3y agoWorth noting that this may still turn out to be accidental, in the sense that all the bombing activity around it triggered sufficient cracking in the wrong places that the normal forces (made worse by high water levels) caused a failure. To be clear, I'm not saying that this wasn't a strike, or a demolition, just that it could be an unintended failure caused by precision strikes performed on targets very near to the dam. “That latter point means that, like all concrete structures, concrete dams will crack. These cracks will be tend to be vertical, since the concrete is free to grow and shrink in the vertical dimension, while the canyon it spans is of a fixed dimension. While an arch dam will have the pressure of the water pushing these vertical cracks closed, a gravity dam has no forces acting along its axis--well, except for the temperature changes. The easiest way to deal with this is to provide a known place for the concrete to crack. Therefore, the dam is divided into monoliths, where each monolith is a separately-placed block of concrete that is more or less structurally independent of the monoliths next to it. The dividing lines between monoliths are contraction joints, and will open and close with temperature changes, sometimes quite dramatically. This is the same reason sidewalks are cut into squares and concrete highways have the joints that go "ba-dump" as you drive over them--the concrete will crack, so provide a way to make it crack in a controlled, pretty manner. [...] This will hold true for all of the concrete, but once you get to the foundation, it gets a bit tricker. The soil is not a relatively well-controlled material like the concrete. It's typically full of joints and is permeable. At the base of the dam, it's typical to assume that the full pressure of the forebay is acting at the heel and the pressure of the tailwater is acting at the toe. The total force acting upwards is typically pretty large, which is a problem: this pressure will reduce the forces acting on the foundation, and therefore the force squeezing any joints in the rock. If you remember from high school physics, it's typically assumed that frictional forces are proportional to the force squeezing two surfaces together. Therefore, this uplift pressure can reduce these forces enough that a wedge of foundation rock will slide with the dam in a foundation failure. This is the typical cause of failure in a large gravity dam. I've shown with a dashed line what that uplift pressure would look like under the monolith, if we let it reach its natural state. However, we have some tricks that we can use to dramatically reduce this uplift pressure. I've drawn a grout curtain and foundation drains extending from the bottom of the dam. The grout curtain is a "wall" of portland cement grout, formed by drilling through the bottom of the dam from the drainage gallery and injecting the grout under pressure. It's typically much deeper than I've shown here, as I ran out of room on the paper. This curtain will increase the path length for flow lines, which will primarily serve to reduce the volume of water flowing under the dam. ” -- “Effort Post: Concrete Gravity Dam” https://www.datasecretslox.com/index.php/topic,215.msg3582.h https://www.datasecretslox.com/index.php/topic,215.msg3582.h...

- _kbh_ 3y agoThis attack is a flagrant violation of the Geneva convention and a war crime. Russia must be punished for doing this or allowing it to happen.
- nikanj 3y agoBut punishing russia is bad for the economy so EU will issue very strongly worded press releases instead
- BasedAnon 3y ago*punishing russia is a threat to your own citizenry which relies on the economy to feed their families. The economy isn't some alien abstract entity.
- martindbp 3y agoMore weapons and permission to strike military targets in Russia seems like a proportional response. Otherwise, what's the response for blowing up a nuclear power plant in the future? Slap on the fingers? Russia keeps escalating, it's clear now that this can only be allowed to end with the full defeat of the Russian military. Whether the dam was blown up or collapsed due to damage is just the difference between shooting someone and slowly poisoning them, it's still murder.

- 2-718-281-828 3y agoif we're already at it - have you heard about the freedom of russia legion? allegedly russian citizens turning against their own government. everything i could gather about that group smells to high heaven and nobody questions that narrative. pro-ukrainian media basically just praises those selfless heroes for their action. but none of it makes any sense. neither psychologically, nor militarily, nor socially, nor politically - any theories on what's going on with that?
- polotics 3y agoOh wow how did you manage to get good sources about the state of the CIS's psychology, society, or for that matter military? Do you have access to FSB's secret polls? How does polling work if the wrong answer gets you 15 years in a penal colony?
- kuboris 3y agoThe destruction of the Nova Kakhovka dam by Russians follows almost exactly all the other heinous crimes Russians have committed: 1. Execute the crime 2. Laugh and brag 3. Realize the catastrophe 4. Change the story and blame others https://twitter.com/Tendar/status/1666033978841636866 https://twitter.com/Tendar/status/1666033978841636866
- skjoldr 3y agoI want to remind everyone that the irrigation of the entire south Kherson oblast depended on the Crimean channel, providing around 17% of Ukraine's agricultural output, and the water supply to some of the largest cities in the area such as Kherson and Krivuy Rih was also dependent on that water reservoir. Not to mention the colossal flooding and displacement of tens of thousands of Ukrainian people. This act had ruined a chunk of Ukraine's future. It's extremely unlikely Ukraine had anything to do with it or anything to gain which would compensate the economic loss.
- gomizari 3y agoUkrainians confessed multiple times they attacked it with HIMARSes: 1) https://www.bbc.com/russian/news-62533233 https://www.bbc.com/russian/news-62533233 2) https://www.washingtonpost.com/world/2022/12/29/ukraine-offensive-kharkiv-kherson-donetsk/ https://www.washingtonpost.com/world/2022/12/29/ukraine-offe... "Kovalchuk considered flooding the river. The Ukrainians, he said, even conducted a test strike with a HIMARS launcher on one of the floodgates at the Nova Kakhovka dam, making three holes in the metal to see if the Dnieper’s water could be raised enough to stymie Russian crossings but not flood nearby villages."
- _kbh_ 3y agoThe Russians intentionally increased the water level of the dam to cause the most damage and then intentionally blew it up. At least two Russian soldiers have said they would blow the damn / they blew the dam and have admitted as much in camera. Russia was celebrating this before they realised it was a war crime then they went into their typical deny and deflect everything mode.
- gomizari 3y agoIt's probably another way around: Ukrainians intentionally increased the water level of the dam, since they control dams up the Dnieper river.
- _kbh_ 3y agoOr you know since Ukraine doesn’t control the literal weather it would be hard to control the water level in a river. Russia controlled whether or not they opened the spill gates they didn’t and it is obviously an intentional build up to do as much damage a possible.
- Chief180A 3y agoIt look like the most anticipated Ukrainian offensive had begun, but was blunted by the Russians After this occurred, it stands to reason that the Ukrainian government would like a reason for not losing any more men and material so why not blow up the dam and damage most of the defensive positions the Russians had prepared and give an excuse for not going on with the offensive. And of course ask for more money and weapons so who did this benefit and you don’t have to be a mental giant to figure out that this was more damaging to Russia and the Crimea than to Ukraine. And remember, we were all told that the Russia blew up its own pipe line in the North Sea as well, confirmed by US officials both military and state department, of course they would not lie to us again right? Look at the lay of the land and facts, the Crimean region relies on that water for agriculture and industrial/domestic water supplies much more than the Ukraine does. Think for yourselves and don’t be led around by politically motivated people.
- Chief180A 3y agoThink for yourselves look at facts Are there pictures of an explosion? Seems like there should be with all the satellites and drones in the area. The Crimea region depends much more on the water from that dam than the Ukraine does for agriculture and domestic water sources. Who lied to us about the Russian Pipe line being blown up saying Putin did it and now we know that the Ukraine did it of course with the knowledge and probable help of the US. Ukraine offensive had started and had been stopped.
- _kbh_ 3y ago> Think for yourselves look at facts Are there pictures of an explosion? Seems like there should be with all the satellites and drones in the area. Yes there is there’s even a video of it. > Ukraine offensive had started and had been stopped. The offensive hasn’t even started those tracts of land Russia is losing to Ukraine are from _probing attacks_.
- KETpXDDzR 3y agoSome russians bragged about putting explosives at the dam half a year ago: https://m.youtube.com/watch?v=arUHJzXCfsU https://m.youtube.com/watch?v=arUHJzXCfsU
