Seems like dams would be an ideal target for a terrorist attack if that were the case. After 9/11 they massively restricted access to a lot of dams. You used to be able to see a lot of coll stuff in the Hoover Dam and it's all off limits now. The Kensico dam in NYC used to have a road over the top and it was closed for 8 years and then restricted to bicycle and foot traffic only.

Psycho Society posted:imo the best plan right now is to fix the main spillway while water ingress is low with an rear end-ton of concrete. Turn that poo poo up to 11 to protect the top 30 feet of the emergency letoff from crumbling and smashing the town. I don't know if they've got enough time for that. They essentially have two days to do this, in pretty bad ground conditions. I don't even know if the concrete they'd need would set in that time frame, let alone be solid enough to hold together (IANA civil engineer). There's a real issue of these spillways being undermined and that hasn't gone away even though the water isn't going over them in massive quantities anymore. They've gone from "It could go at any minute!" last night to "It could go really soon!" today. It'll probably be months before the spillways are actually safe again, though if they don't get hit by more rain after the next set of storms coming through then I'd expect them to be able to keep the level low enough until it's fixed that a failure won't be an immediate problem.

They fortunately end up not doing that, but as it was just upstream from Mosul and a bunch of there smaller towns.... that would of been pretty horrific.

IAA civil engineer who works on dams and you couldn't place the necessary amount of concrete fast enough to make a difference, even if there was already a passable road leading directly to the hole. Dropping in sacks of rock via helicopter is pretty much the best option here.

A Horse Named Mandy posted:It's things like this that remind me we spent $1.7 trillion in Iraq, plus ongoing veteran benefits, with nothing to show for it. Maybe history will eventually regard that conflict on the same level as the Pyrrhic War or the Battle of Bouvines, but for now it seems to have gone down the same memory hole as the rest of the Bush years. We currently spend more money on military than all other nations on earth combined, and by a large margin. We put trillions into an airplane that cannot fly effectively and will likely never be used in actual combat. We have no enemies capable of being a significant threat the the states, and those who are capable have no reason to ever go to war with the USA. The USA is exceedingly capable of funding social healthcare, infrastructure, cleaner energy, better education, and much more. The US is able to fund these things better than any other nation on Earth, but it doesn't and it never will.

withak posted:Once the reservoir is full and the emergency spillway is running then the dam has is zero flood control capability because water will flow out as fast as it is flowing in. as i understood it they were not running the main spillway as hard as they could because it was damaged and causing erosion, so they let the emergency spillway take some of the pressure off... until that one started eroding even worse, so then they opened up the main spillway even more. now the water level is below the emergency spill lip but the main spillway is turbo hosed. but they're still largely in control of water release

Once the water is running over the emergency spillway then they lose some control because they can't release any slower than the inflow rate. They can still release faster (and were doing so) by using the main spillway at the same time as the emergency spillway. It appears that they were opting to increase damage to the main spillway to try to preserve the emergency spillway for longer.

What's the main drawback of using the primary spillway? How much erosion would it it take it compromise the integrity of the dam proper? It definitely seems like the best idea given any use of the emergency spillway could result in 30 feet of lake oroville to come pouring out with a vengeance

Psycho Society posted:What's the main drawback of using the primary spillway? it's broken and spewing chunks of concrete and other bullshit everywhere. basically they were like "ok well this sucks, our main spillway is all hosed up and it's gonna be expensive to fix if we keep letting this much water out, so let's give the emergency spillway a try *the emergency spillway is even worse* ok ok bad idea i guess we're just gonna have to do the expensive thing" Psycho Society posted:How much erosion would it it take it compromise the integrity of the dam proper? way more than is possible rn, the dam is a separate structure. the problem is that the local government cheaped out on making the emergency spillway robust enough to handle this job without falling apart, but there's no way to prove that it's not capable of doing the job until you have to use it and it almost fails and you end up evacuating hundreds of thousands of people in the middle of the night boner confessor fucked around with this message at 18:45 on Feb 13, 2017 |

If the damaged main spillway is no danger of undermining the dam, we'll just use that then. We haven't had to use the emergency spillway in a hundred years so careful management of water levels *should* give us time to fix everything we need. As long as it doesn't rain too much.

It definitely seems like the best idea given any use of the emergency spillway could result in 30 feet of lake oroville to come pouring out with a vengeance The dam proper is in virtually no danger. All of this stuff is happening a fair distance from the dam on the opposite side of a bedrock hill. Right now releasing through the primary spillway (the concrete one) is the least risky because the damage there is unlikely to cause uncontrolled release of the reservoir. The erosion there has made a big, ugly, expensive-to-fix hole but it is likely down to bedrock now and will erode at a much slower rate going forward. It is likely that they will continue to use it as much as possible in advance of the rain later this week to get as much water out as possible and minimize the need for the emergency spillway later. The emergency spillway is riskier because the erosion of the soil at the top of the hill could cause the weir at the top to fail and and create a deeper notch in the hillside, which would result in very severe flooding (but still not total loss of the reservoir). withak fucked around with this message at 19:13 on Feb 13, 2017 |
