Fasdar posted:What is the chemical that (I assume) displaces oxygen in these? Carbon tetrachloride. It doesn't just displace oxygen, it poisons the reaction by decomposing to release chlorine that scavenges the free radicals that are propagating the combustion. Pretty much the same way that halon fire suppression systems work (which is no surprise because it's a halomethane just like halon is, another name for the compound is tetrachloromethane).

That is the regular spillway that's chewed up. The emergency overflow spillway is fine. It's just that there are no gates or anything, no water goes into it until the lake is filled and there is no way to control it. So if it keeps raining hard all that extra water just goes out completely uncontrolled.

The lake behind it will be gone, however, because the spillway will have eroded the the adjacent hillside to the bottom.

Since the spillway is not physically part of the dam, like bunches are, I'd be in the camp of just let it wash out and rebuild it. Not having any idea what the geology is around there, the only thing I'd be worried about is the undermining of the spillway getting so bad that a mini canyon is created next to the dam pretty quickly, and draining that lake very, and uncomfortably quickly. If it's a clay-y sandy soil, uncontrolled discharge might look a little like this except about a billion orders of magnitude bigger (sorry for the Michael Jackson soundtrack): https://www.youtube.com/watch?v=KFzqike1Z0A e;f,b Deteriorata got it

I’m no expert in Oroville geology, but it’s entirely possible that that hill is one giant rock. There’s one looming over the town.

Here’s a geology report from 1951, years before the dam was built. I’m sure there are more detailed and recent reports available, but whatever; age adds character. quote:An overpour spillway can be utilized at this site by affording moderate protection to the rock near downstream toe. A natural saddle at about elevation 865 and a ravine below it offers a suitable spillway location. Rock of good quality should be found about 30 feet below surface in this saddle. Lining would probably be needed for a short distance from the spillway lip.

I somehow missed that the emergency "spillway" was just the hillside next to the dam. Nice. And here's a classic dam failure for everyone https://www.youtube.com/watch?v=cdOGPBnfoKE Also this one, we took a field trip there in geology class: https://www.youtube.com/watch?v=_6AvEZO34xI jamal fucked around with this message at 05:21 on Feb 10, 2017 |

Platystemon posted:Here’s a geology report from 1951, years before the dam was built. Yep, you nailed it. Metamorphic is way better than sedimentary, and at only 30 or so feet is excellent. As long as the gates and the gatehouse hold it'll be a big rear end mess, but it's better than the whole dam going. Now, if the rain continues... I hope they're (and I'm sure they are) checking the weep lines at the base of the dam for increased flow.

Oh jeez that looks unpleasant. Wait oh god why is everything on the shelves red... oh. Oooooh fu edit: here we go: A drunk man set a fireworks shop on fire in northeast China's Shaanxi province, state media has reported. State broadcaster CCTV released surveillance video footage from January 21 showing the 45 year-old man, surnamed Li, buying a pack of fireworks from a local seller in Hanzhong city and then proceeding to fire them inside the store. CCTV said police had already confiscated 259 pieces of fireworks and firecrackers from Mr Li which he had stored illegally, later handing them over to the shop for "temporary storage". Mr Li had reportedly tried to recover the fireworks several times but failed, CCTV said. On the night of January 21, an intoxicated Mr Li bought a pack of fireworks and fired them at the shop about 8pm local time, CCTV footage indicated. Mr Li turned himself in to the police soon after the incident occurred, and was arrested on suspicion of arson, CCTV said. China has a long tradition of using fireworks to celebrate the Lunar New Year, which fell on January 28 of this year.

Mozi posted:I know the 'plan' is to let the spillway erode until it can be fixed, but I wonder if continued erosion could weaken the spillway above the 'pothole' by carving out under it? To a degree, yes, but at this point I think they're relying on the rock formation under it. According to the previously posted geology report, there's metamorphic rock not too far from the surface. That spillway channel is gone, though. I think, at this point, the only other thing that can go that would make the situation a lot worse would be the gatehouse, but I'm assuming it's pretty well put together -- hopefully bonded to the bedrock below. poo poo got real, real fast. I coop'ed with a flood control district my first two years of college, and they had plans to deal with situations like this. Some of them were, like, "we did our best, just gently caress it and pray".

I guess this is why 'engineers' and 'software engineers' aren't quite equivalent in that 'just let it crash' has slightly different effects.
