EssOEss posted:Am I seeing it right that the water is flowing through holes and not going over the top, which is higher than the water? That's what prevents the boats from going in? Or is it simply due to the fact that there's not much water going over the lip, so any boats would get stuck on the lip? A very thin 'membrane' of water is spilling over a rigid lip that's just below surface level (and why the surface remains at that level). Imagine slowly lowering a large bucket into a still pond juuust low enough to achieve the most minimal, uniform inflow of water over the rim-- that's what's happening. Edit: StrangersInTheNight posted:ok but what does 'fine' constitute? those boats could still fall in, and what happens if they do? It'd take some pretty significant effort to take a kayak full of dad bod and move it up and over a big wide concrete lip in <1" of relatively gently flowing water. Not undoable, sure, but it's not a whirlpool like the plug was pulled out of a tub-- it's a horizontal version of the little hole in the bathroom sink that prevents overflow.

yeah I think the spillways that really get people are more common on rivers and are called weirs. They generate nasty currents that will suck you down and keep you there like this  though I doubt that a person can keep oriented enough to find the bottom much less swim out

Practical engineering has a video about weirs and I think there's one type where you just can't really get out of it at all.

yeah stuff can get stuck in a hole like that for literal days at a time. sometimes a person drowns in one and the rescue/recovery crew just has to wait for the water to spit the body out.

BuckyDoneGun posted:Sweet time lapse: They can't get at the burning straw layer because it has a layer of water proof butybutymol (sp?) on top. Why can't they run ahead of the fire (they can see which direction it's going) and rip a chunk of roof up, start pouring water in there? Roof is ruined anyway. This way they could save a portion of it vs expected 100% loss. Good work on the evacuation though. Looks like they had that sorted.

I think that the idea is generally not for firefighters to risk their lives to save a building. If it’s evacuated and no threat to the surroundings, let the insurance companies worry about the roof. Just because you can see which direction it’s going doesn’t mean it hasn’t undermined the section you’re going to step on.

Stepping foot in a burning building is far different than stepping foot on a burning building.Phanatic posted:I think that the idea is generally not for firefighters to risk their lives to save a building.

Just because you can see which direction it’s going doesn’t mean it hasn’t undermined the section you’re going to step on. This is the approach to forest fires they took when I lived in AK. If it's not threatening anyone, just let it go. Of course, when it does threaten someone, the results look apocalyptic. I can't find the pic, but there was a forest fire that made its way on to fort greely and burned down a few buildings and it looked like an apocalyptic inferno.

On hearing about the raising of the 11'8" bridge, overpasses around the world have started stepping up to fill the void. Thornbury, Melbourne, Australia, about 25 minutes ago. I don't think my wife's making her meeting.

kimihia posted:I'm not a roof-opening expert, but that's no reason for me to not spout an opinion! Firefighters will make cuts to try to limit the spread of the fire by releasing hot gases before they start igniting things and to gain access to fight the fire. Here's an example: https://www.youtube.com/watch?v=fwPYHg-NQ0Q These guys have a lot of expertise to know what they can and can't do with every different kind of structure out there. Some types of construction just shouldn't be cut or aren't safe to be up on when aflame. Also, some membranes will jam the saws they use to cut so it's not going to be an option in the first place, but I dunno any of what was going on in the case in question.
