Dammit. Every time I read something like this I get nervous and spend more money stocking up on stuff.

Looking around the house... Let's see...

Shoes... need another pair.
Tires... OK.
Car was just serviced, should be alright for the next year. Ah-HA! Need new wiper blades.
Meds... have enough for a year. OK.
Spare phone battery... OK.
Trash bags... OK.
Cleaning supplies... OK.
Cat food: some ingredients and probably the bags are from China. Get more.
Coffee: the bags or canisters probably come from China. Get more.
Rice, beans, staples... pretty good. Haven't been to Costco since Feb. when I saw Covid coming. Time to make another run.

Think about all the stuff that doesn't come from China, but a component or ingredient or even just the container it's in is made in China.

Think about the trucks that bring the stuff to the store. Trucks needs new tires and parts, but the tires and parts are made in China.

If this dam goes, expect prices to rise another big notch.

How droll. You're the master of drollness.

It's not the design and the facade, it's the material used.

Ever seen hollow bricks and foamcrete?

That dam is just, well, "massive" doesn't begin to describe it. Prayers for all the poor souls downstream.

Re: Big Trouble in Little China

What I find so alarming is that the original concept of a spillway was always placed at the top of the dam, so that any overflow was at the rate of the flow at the surface. If they have designed a dam where the overflow is drawn from the base of the dam in those hugely destructive flows; then there must be every possibility of the destruction of the structure from those flows at the base. In which case the failure is only a matter of time.

Not an engineer,but maybe it's to relief the pressure at the base of the dam and because mud sinks, to let some of the mud flow out?

I'm just wondering if the reduction in carbon emission due to Covid has caused the abnormal rain patterns this year. One thing leads to another....

In point of fact, it turns out that the spillway is at 175m but the water height was reduced at a much lower level. From what I can make of it they were reacting to a water flow that had overwhelmed towns and cities upstream, and that in so doing they pushed the flooding problem downstream; making no one happy.

The pressure at the base of the water column remains the same, regardless of if the water is in motion or not. My point is that such a massive water flow will erode the linings of the outlet tubes; water has a way of eroding everything . . . eventually!

The dam is suppose to last 100 years...

Or, again . . . how not to make a video; instead an exercise in unedited conversation; constantly repeating dialogue to a classic example of doing something to the n degree.

Re: Big Trouble in Little China

Well
Its still stood there, from what I can see there is little sign of "Panic repairs"......

Re: Big Trouble in Little China

Very true Mega, but what I was most disappointed about in the above video is that they never seemed to be able to think of a strategy; to at the least get a long range view along the line of the dam. As you so correctly define, little sign of panic repairs . . . . .

the CCP is very "Jumpy" .....& then a group of western's appear.
They did the best they could without causing "trouble" for themselves....
