Do you comprehend watersheds?


Lol So you don’t know the purpose of a watershed then obviously...point would be to divert the current water flow to prolong the high influx of water Into the 3GD in hopes of mitigating the risk of the dam breaching....the water would make its way back to 3GD eventually but not at the rate it would normally if not diverted causing excessive loads on the dam that it obviously can not withstand .....this is not taking into account the fact that these other watersheds up river may already be full and not able to take on any more water....but still doesn’t take away from the OP and questioning how one is going to reverse the physics of gravity to divert flow upstream....dumb dumb now frick off

I think the person was pointing out the moisture cracks that are visible and theres a huge one behind that ladder.

Not trying to be a contrarian, but about that ladder: What that looks like to me, is a wire safety cage around the ladder. In the U.S., that would be made out of expanded steel and much stronger. Would be required on a ladder that high. That one seems to be made out of something like a heavy chicken wire. You barely can see the wire, and I think where it looks like a crack on the wall, is just the angle of the photo, and you're seeing where the screen is folded. That's what I think I see there. There are some breaks and cracking at the corners that I see.

No sense in debating if it's cracked or not. If this thing goes, we're all going to know.

Cliffs?

Is this thing going to break? Is it getting better or worse? Upvote if it will break. Down vote if it won’t.

Thanks. I can’t read that many pages abt speculation on concrete structure

I don't want to see a complete failure of the dam, it would just kill too many people. I hope it becomes useless for generating power. That would be the best outcome to me.

Answer: no one here really knows. But if this dam breaks, we are going to feel it in the USA overnight AT LEAST economically.

How economically? China doesn’t buy that much from the US. It will increase the exodus of factories I assume. What am I missing?

Supply chain issues for US producers.

How much farmland would be in the impact zone?

Yep - if this happens China collapses and the US economy tanks in the short term.

I dont believe that this event would tank the US economy.

There would be supply chain disruptions, but tanking the economy is a bold claim.

It would hurt us pretty bad but that's why he said in the short term.

It would crush Europe.

Hopefully it doesn't fail but it's like watching a train wreck. You can't look away.

Do a little search on the amount of goods this region produces that would immediately be underwater.

It is a major concern for the US and the world. Just the amount of medicine produced for the world would create a massive problem.

March 2020 says hello. It has already been disrupted. This speeds it up no?

To the poster that talks abt crushing Europe,
How so? Again, supply chain is being dealt with by companies. Urgently.

I mean, he’s not wrong. You can lag and attenuate a peak flow in a stream by diverting and slowing down flows within the watershed.

Total volume of water is the same, but if you can lower the peak flow at the dam, you can lower peak forces felt at the dam. The trade off being that there will be above average flows at the dam for longer.

If they are concerned that a peak flow will overwhelm the dam, I can guarantee they are considering flooding areas upstream, assuming that’s an option that’s available.

Upstream is where the heaviest water is currently and already experiencing extreme flooding though, right?

He is wrong. The concept of diverting that amount of water long enough to slow down the increasing forces on the dam is impossible. That may work for a small amount of water but the dam reservoir is overwhelmed as is the Entire watershed. There are 2 main diversion channels that are already at capacity.
This is the reason that the engineers are concerned. They have diverted all the can upstream so it’s been a drawn out flood event which is putting exponentially more strain on the dam. And the worst part is that the rain is not stopping anytime soon.

Yeah, but there are quite a few smaller dams upstream, and lower populations, most of the infrastructure, nuclear plants and bigger cities are downstream. What can be done upstream, would depend on the topography. They might be able to blow up some levies and flood larger areas, then pump that water out later and rebuild the levies.
