Despite what is clearly access to an arial vehicle (probably a helicopter), the Reuters images present a much smaller set of viewpoints, perspectives, and scales. Which means that I'm seeing a roughly 1/4 size image with vastly less detail than in the Imgur collection.Ģ. The presentation is a fixed-size image on the page, which cannot be maximised (or the controls for such maximisation are highly nonobvious). I disagree that that's a better collection, on a number of counts:ġ. Thanks for the Reuters collection for comparison. Something to keep in mind in the context of other stories, such as, say, the fact that climate is change at a rate of roughly 1,000,000x faster than normal, presently.Ī point Tucker Carlson apparently cannot grasp, given a recent appearance of Bill Nye on his programme. If the interval is 20s, probably pretty good.
As a comparison, you're in a car moving at 100 kph, and are later moving at 0 kph. The rate of occurrence of things matters, and a factor of 60 or so (as above) is tremendous. The dam, also an earthen structure, was designed with an intentionally soft "plug", that could and would erode before the main dam face, but in a slow fashion, such that the dam would fail over the course of hours, rather than minutes. That was a 1986 event during an extreme rain event. The Auburn Coffer Dam engineered failure has been mentioned (though not linked - it's easy enough to find on YouTube) elsewhere in this thread. It isn't designed for repeated usage, requires massive reconstruction after such uses, and (in conjunction with the parking lot), provides the basis for a "soft failure" of the dam as a whole, as opposed to the prospect of the entire dam face collapsing. The emergency spillway, as I've only learnt reading up on this story within the past day, was designed as a "use once" capability. To that extent, the spillway damage was a massive management failure. That is: its design intent is to accommodate such flows, without failure of itself or incapacitating damage. The main spillway is the mechanism by which, when needed on a normal basis, major discharges can be accomplished. Noted, though "normal" and "major" are somewhat semantic.
