The one of the dam shifting seems to indicate it's only a matter of time.
Yes. I'm no expert so it may not mean what it suggests to me but that one really got my attention. Very scary and I don't know what could be done to rectify that, if it is necessary.

Wow.
Barely comprehensible, that much at once.

Jimbo54Wow, 400 million is roughly 1/3 of the total population of China. It's hard for me to wrap my head around that. God help those people.

Here is another for you - the per second emergency discharge is 66,000 tonnes of water.
To be even more mind bending, at the rate it is being discharged, it would take 93 days to fill Lake Erie to the brim if it was empty.
Or...The weight of water being discharged every 132 seconds exceeds the weight of cement used to build the hoover dam.
Last, but not least - It can fill 24 olympic swimming pools per second.July 15, 2020, 04:11 PM

I don't have an Engineering bone in my body, so those numbers, nosler, are just beyond my comprehension, and thanks for tying the visuals to them. Good LORD!!!
I hope this all works out.....

Skins2881280,
Those numbers are almost impossible to comprehend. 400m people at risk. I wonder what is meant by that? Death, loss of property? An event like that even if it's just loss of property would rank up there with the greatest cataclysms ever to face man kind.

The way I have read this from other locations, the flooding associated with a full river, which is considered +6 meters over base levels puts roughly 10 million people in "danger". When you add an extra 2 meter to that (+8 meters), 50 million people would be considered in danger (their lives take them within areas that would flood). Because the river is already at full capacity (as is the dam), releasing the contents of the dam (39 cubic kilometers, which is 1/12 that of all of Lake Erie) would raise water levels by 30 meters, and that flood plain houses 400 million people.
Consider a 32 foot tall wave that is a 3 kilometers wide, that is takes 10 hours to subside.
IF you saw the damage created by the WIXOM dam break in Michigan, think about that to a scale of 50,000.

Yuck it up

280noslerFWIW, I'm trying to contextualize, I think it this scary as hell.

I cannot even conceive of a loss of life on that scale.
I suspect that the ChiCom government can, and further suspect that they just don't care that much. Oh, they care about the flooding, but not because of the impact on the people.

6gunsIf the loss of people affects their manufacturing industry...and I'm sure it does, they'll care.

RHINOWSOAnd the sad thing is any losses the CCP does report, you know its at least 3-5x that.
July 15, 2020, 05:32 PM
Mars_AttacksThose huge houses just being swept away by the river!
What a nightmare to wonder if the dam will collapse and there will be nowhere to run.

Horrible to watch.

adorI just hope that dam hold the water until the rain stop. And NEVER burst. Just imagining the power of the rushing water going through the places where people live scares the living hell out of me.

WaterburyBobI hope that dam holds, but I have little to no confidence that the corrupt system that built it did it right.

To put it in other numbers that I can relate to better, last year as I recall when the Mississippi River in St. Louis was at severe flood stage (not quite as high as the record 50 ft level in 1993), the flow rate was about 800,000 cubic feet per second. That works out to the Three Gorges Dam flow rate being about 2.6 times that number... 2,112,000 cubic feet per second. That is a tremendous amount of water going where it wants to go.

18Z50Hello Para,
RKI stands for "relatively knowledgeable individual".
I just finished discussing a CARVER matrix thought experiment with several other 18 Cats and a few other neat DHS types. The consensus is the complete and sudden failure of this dam complex discussion would be the single largest loss of life in human history at one time and would have a greater impact globally in setting back the advancement of mankind since the plagues and the resulting the dark ages.
We live in interesting time.

parabellumThank you. I'm gonna nip this one in the bud. If any member wants to say "relatively knowledgeable individual" then they should say "relatively knowledgeable individual" and not RKI.
Type out those three words. You can do it. Feel the burn, push through it and you'll get your second wind.
