Interesting take, would nullify everything most have been hypothesizing... TL;DR:
- You can see that after the "briged-part" that is closest to the UA side gets blown up, the gates that let water flow on that side rarely are seen open on sat images.
- The water levels are very high this time of the year bc of ice melting.
- The engineers operating the dam on the RU side where either inoperant/unwilling to open up the floodgates on the side closest to UA... again, either they did not know what they were doing, or they were afraid of getting shot while operating them (you have to man a crane that moves on top of the dam via rails to open the gates).
- The video shows satellite images of the dam only operating one floodgate, the one closest to the RU side.
- Close to the date in which the dam collapses, there's evidence (satellite pictures) of a nearby road, that's part of the dam, collapsing close to the RU side.
- The author of the video says he consulted with some Civ.Engineers and other SMEs and it makes sense to assume that the water being released only via one floodgate (which was under immense pressure, can be seen as turbulent water) could have "digged" down on the dams floor (which is dirt and sediment), and might have weakend it's foundations.
- There's also satpic evidence that the dam was overflowing... which ain't good from an engineering standpoint.
So there you have it, it might have been operator negligence and even bad management, that caused this disaster. Obviously, in the end, the cause is the war itself. And everyone here knows which to blame for it (and I'm not going to get into that discussion).
The other thing the author of the video touches upon is the fact that he's not sure that blowing the dam is a great strategic advantage for RU. If you guys want to comment on that, I'm very interested on your take.
Finally, there is also the point he makes that they wouldn't have needed to blow up the dam itself, but could have just blown the power generator compartment, which has much easier access and is also part of the dam itself. This wasn't the case, so it begs to ask the question of why the RU would have gone through the trouble of blowing it up from where they allegedly did.
