Oroville Dam Rapidly Goes From Bad to Worse - ALERT - EVACUATIONS BEING ORDERED NOW! Spillway Failures Are How Many Earthen Dams Fail!

ALERT!



here is the link to the original thread
Thread: California's Lake Oroville Main Spillway Severely Damaged/Eroded. Oroville Dam's Recently Reconstructed Main Spillway Fundamentally Flawed
Unfortunatley I cannot pin because this thread was already pinned 3 times (max)

If an evacuation notice is given, people will not be able to get out.......stay alert

Thanks for posting a new thread, which can be pinned.

That latest video leaves me at a loss for words.

Will post two, I hope. The first was earlier today, the second is closer to the present.

... you do realize that the spillway structure is a completely sepErath structure from the damage correct. Because if you don't understand that then every thing after is not worth talking about.

Separated by (hopefully) 100% bedrock. Given enough time, moving water wins, every time.

The generator outflow is unusable, the intakes are clogged.

The primary spillway is slowly self-destructing, despite being run at about 25% designed capacity.

The emergency spillway is holding up, it appears, but it is an uncontrolled spillway, which simply allows water, of any amount, to spill over its top.

I hope the bedrock lasts longer than the rainy season and snow melt.

Read this and read this carefully

Overtopping or overflow of an embankment dam beyond its spillway capacity will cause its eventual failure. The erosion of the dam's material by overtopping runoff will remove masses of material whose weight holds the dam in place and against the hydraulic forces acting to move the dam. Even a small sustained overtopping flow can remove thousands of tons of overburden soil from the mass of the dam within hours. The removal of this mass unbalances the forces that stabilize the dam against its reservoir as the mass of water still impounded behind the dam presses against the lightened mass of the embankment, made lighter by surface erosion. As the mass of the dam erodes, the force exerted by the reservoir begins to move the entire structure. The embankment, having almost no elastic strength, would begin to break into separate pieces, allowing the impounded reservoir water to flow between them, eroding and removing even more material as it passes through. In the final stages of failure the remaining pieces of the embankment would offer almost no resistance to the flow of the water and continue to fracture into smaller and smaller sections of earth and/or rock until these would disintegrates into a thick mud soup of earth, rocks and water.

Therefore, safety requirements for the spillway are high, and require it to be capable of containing a maximum flood stage. It is common for its specifications to be written such that it can contain a five hundred year flood.[5] Recently a number of embankment dam overtopping protection systems have been developed.[6] These techniques include the concrete overtopping protection systems, timber cribs, sheet-piles, riprap and gabions, reinforced earth, minimum energy loss weirs, embankment overflow stepped spillways and the precast concrete block protection systems.

Thanks for the info man, and hope you are recuperating from your illness.

SOMEBODY GET THE 150 PAGE MEGA UBER PINNED THREAD UP HERE
AS A POST 'OPTION'


NOT 'JELLY'.....

so there is no fresh vids from today? at all?

We will eventually be watching the Seconds from Disaster documentary about this. The one with the goofy British narration. Adios Amigos

I will not even speak my dream it was so bad , but I fear this is not over.

AS THE OFFICIAL DOOM COACH...I'VE STATED ON THE REAL 150 PAGE UBER MEGA MEGA THREAD THAT IT IS DOOM LITE UNTIL LATE TUESDAY......

DOOM COACH OUT

I've been watching the electrical tower get closer and closer to the water. I'll be the water will knock it over in a day or two.

I am noticing the erosion is getting intense as it creeps toward the dam.

let it break, destroy california

Are you sure that the water isn't getting closer to the tower instead?

WHY ISN'T THIS RED PINNED?

This is a huge developing story and needs to have
major attention on it.

I had another thought as well...Everyone knows that
the weight of WATER is significant in triggering
fault lines. If this dam should suffer a major breach
and that water does flood the Sacramento Valley, the
water-weight it gives this land mass so close to San
Francisco is like a mouse triggering the ACTION at the
bottom of a mousetrap. Let's all pray the Oroville Dam
stays in tact.


A runaway train is a sad thing to watch.
This situation is beyond bad.

Great job, OP!

Was that tommy Chong narrating? I agree with one thing. It sucks chasing rabbits while you're on a wild goose chase.

oh, but, but, the ennnnnnginnneerrrsss said there's NOTHING to be concerned about....that was news yesterday. It's like Fukashima...but, but, there's NOTHING to be concerned about...does anyone with a brain want to believe ANYONE in charge anymore? So, the hot shots in charge "bug out" and leave the low lives to their own resources AFTER THEY LIE.

some amature Drone footage

Now the water is going OVER THE PARKING LOT AREA
which is NOT part of the reinforced area of the
Dam. This is just unbelievable, you guys. And
the Utube author here is correct, you can't even
get a mental grasp of the SCALE of this thing. He
says to use the huge cement trucks to scale the
overhead images.

Just wow...

I live in So CA far out of reach of this dam but my dog is hyper vigilant and nervous today for no apparent reason. She's very sensitive to environmental things like storms. Just a commentary ....

THe government of California, "no need to worry, our shit dam, it has an emergency spill way."

Me, "it looks like just after the spill way it's just dirt...won't it erode away?"

The gov, "fake news, shut up"

Me, leaving town.........

6 months from now they will be whining about no water due to the spotted owl or some tiny little fish.

Apparently the dam has a concrete core according to this image.

I would post the image but don't know how.
