you know when a damn is breached what happens to that small gap from the water pressure pushing on it right?
people are acting like the whole section of it wouldn't collapse anyway, it only needs one small crack through the wall
I do indeed which is why I pointed out that was precisely why an explosion under water was considerably different to one above, even if its only a few meters below the water level.
Precisely why it would be far easier to lower the water line, drill some relatively small holes, pack them with explosives, wire them up and then blow them all and let water pressure do the rest.
You can do exactly the same below the water line, but its a more expert job than at water level (which to do safely would still be quite expert but the Russia and safe...)
Real video seems sketchy so hard to know exactly how this one played out. But the pictures would make me think 3 or so points were blown and the water pressure has removed all the rest back as far as the nearest strong point in each direction.
By the size of whats gone however it doesn't look like it was a minor crack to me but who knows. It certainly looks like the water is now carving away at the edges behind the dam.
