For a serious reply: of course the level wouldn't suddenly go from not using the emergency spillway, to pouring 350kfps over it. But in a scenario where the main spillway had to be shut off, you immediatley have the emergency spillway having to handle potentially the full capacity of the main spillway (250k), plus if it's also you know raining a loving lot then there's additional input into the lake. The design capacity would have been set by a team of engineers who, just maybe, know a thing or two about gigantic fuckoff huge hydrological projects. The failure here is in the belief that the emergency spillway would hold up - sustaining some damage, but not being rapidly destroyed - by 350kfps of water, and here it is being rapidly undermined by a mere 12kfps of use. e. For reference, the capacity of the Oroville reservoir is 3,537,577 acre-feet. One acre-foot is 43559.9 cubic feet, so the capacity of the lake is approximately 154,096,600,000 cubic feet. There's a looot of goddamn water there, guys. source. Leperflesh fucked around with this message at 03:28 on Feb 14, 2017 |

As an American, it's the only unit of measurement that I can understand.

Football fields are flat. These are all units of volume. I believe the standard American Measurement Comparison for water is the Olympic Swimming Pool, right? According to Wikipedia, an Olympic Swimming Pool holds about 2 acre-feet of water. So the Oroville reservoir is about 1.7 or 1.8 million Olympic Swimming Pools of water.

Leperflesh posted:Hmm, yes, there's a civil engineer working for FERC's statement on the design capacity as reported by the San Jose Mercury News, and then there's the gut feeling of random goons going "yeah that sounds like too much water, that can't have been the design capacity." I'm a civil engineer who works on the design of earth dams in California. FERC engineers don't design anything, they review and approve designs developed by others. The way the 350,000 cfs number was cited in the article was odd. To me, it feels like the answer a staff engineer would come up by throwing some estimates of dimensions into a weir equation in response to a vaguely-worded question from a boss who doesn't really understand what he is asking. Someone at FERC may think that the capacity is 350,000 cfs, but I think it is unlikely that the actual designer of the dam would have counted on 350,000 cfs coming over that weir and running across an unimproved hillside to get down to the river. Not impossible, but unlikely. edit: Alternate theory: I'm not going to do any actual calculations, but I wonder if you get 350,000 cfs if you calculate the theoretical flow through a rectangular weir with the width of the emergency spillway and a height equal to the available freeboard above the emergency weir elevation. Like if an intern at FERC was given 15 minutes to answer the question "could water get through this weir fast enough to keep the dam from overtopping" without knowing anything else about the site. withak fucked around with this message at 04:46 on Feb 14, 2017 |

I mean, we know from recent evidence that the stated capacity was wildly wrong. The origin of that error has yet to be determined. My main point tho was that goons just flatly stating that 350k was an absurd number did not appear to be aware of the scales being dealt with for this dam. In other words, it is not absurd for dam engineers to plan for a 350k capacity aux spillway, given the main spillway's 250k capacity. When you do engineering, you overdesign. You say "realistically we don't anticipate ever dealing with more than 200k, so let's design for 350."

Platystemon posted:Technically only the minimum depth is specified. OK. So, technically the center of the earth would be a one-dimensional point, which would mean the swimming pool that deep would have sides that angled slightly towards one another, creating a very very very long inverted four-sided pyramid shape. Instead we'll assume that we're just gonna have a rectangle of the same dimensions all the way down. Also, the earth is an oblate spheroid, so the distance from the surface to the center varies by latitude: 6,353 km to 6,384 km. Let's use the mean radius of 6,371 km (3,959 mi). Because they are sensible, the IOC specifies their pools in meters: a full Olympic pool is 25x50m. A volume 25m x 50m x 6,371,000m is 7,963,750,000m3. Converting to cubic feet with a factor of 35.3 gives us a volume of about 281,120,375,000. So that olympic swimming pool that goes to the center of the earth holds 281 billion cubic feet of water. The reservoir holds about 154 billion cubic feet. So the full capacity of lake Oroville is a little over half the volume (55%) of one Olympic swimming pool that goes to the center of the planet.

I actually did the arithmetic for a swimming pool that reached to China and figured that halving that was close enough for government work. “One swimming pool that reaches to Earth’s core” sounds nearly as good and is accurate to within 20%.

Litany Unheard posted:White House reps are currently denying it so who knows. They're denying it, but the DHS confirmed that this is a plan that's been floated around since January. Whether or not it'll happen is another matter entirely, but yesterday's presser has shown that Trump is entirely willing to do something massively stupid against the advice of his own, closest advisors. So even if someone like Bannon or any one of his toadies warns against something like this, there's no guarantee it means Trump would back down on trying to get National Guard out on the streets.

While you're drinking, pour one out for the 2006 state single-payer bill which passed and was vetoed by Schwarzenegger. For anyone else who gets as weepy as I do at the possibility of really for-actually making it happen this time, Healthcare For All has suggestions. You can also just harrass your current representatives through all published means.

It would probably cost them less in the long run, but would hurt this quarter's numbers as employees with health problems (or with family members with health problems) would not longer see quitting as a potential death sentence. In corporate America if something doesn't improve this quarter's performance metrics then it doesn't exist.

I think it's more to the point that single-payer was never really sold to business as "you don't have to pay for healthcare anymore" and consequently they're basically meh on it overall. Meanwhile, insurance and big pharma are VERY invested in it never happening, since it would increase competition and decrease profitability. So it's a case of apathy vs. two highly engaged and powerful lobbies.

Hmm lets see what else these fascists have in store for our great state? http://abc7news.com/news/trump-administration-halts-$674m-caltrain-improvement-grant/1760998/ The trump administration is going to withhold nearly $700 million dollars that were to be used for the high speed rail project (specifically for electrification of CalTrain which is a necessary step for a stretch of track that will double as the future HSR corridor on the SF peninsula), because state republicans hate it and complained. At what point does california just say that it no longer recognizes the authority of the federal government, and stops sending them tax money? I'm sure we have enough gay stoner immigrant terrorist death squads to defend ourselves from federal troops. godammit
