February 14, 2007: Big-ass drain hole - Page 2

Elspode · 02-15-2007, 09:06 AM

I guess the spillway shaft itself is just a tunnel drilled through solid rock? I'd like to the see profile of that...I mean, it has 770' of drop, and has to make a bend from vertical to horizontal at some point. The water pressure at that bend must be tres' impressivo.

Pretty sure it's concrete all the way, constructed integral with the dam. Hoover/Boulder Dam, however, uses bypass tunnels through the rock that are fed by a spillway channel. I've seen that setup and those tunnels must be 50 feet in diameter.

Two views of a dry glory hole.

It should be swirling counter-clockwise, this big ass-drain hole.

Man, what a ride.

A dam a few hours away had to put a fence around there "HOLE " because drunk idiots were waiting for the water level to drop ( when there was just a trickle running thru ) and jumping down the "HOLE " on rafts , After 3-4 of them came shooting out a piece at a time , the Gubment put up the fence .

I used to work with a guy. the guy was named Dave. Dave used to manage an adult book store. The book store had those little booths in the back with the coin operated porn movie machines. Shortly after he took the job, he realized that there were glory holes between these booths. Disgusted, he patched them over with plywood discs. After a month, his video sales had dropped in half. So, he removed the patches, and sales went right back up.

wonder how long it would take to make it through the 700 feet?

Probley the rest of your life !!!

This reminds me of an ex-girlfriend.

It doesn't look real to me. The white water in the first pic looks photo shopped.

Fortunately for life, as we know it, on Earth, water has the amazing property of cohesion which allows it to be a liquid.
As the water flows over the rim, it's all cohesively connected and uniform, then gravity causes it to increase speed. When the water accelerates it gets torn away from the slower water behind and the faster water ahead. Droplets form of the water that's close enough in speed to have cohesion triumph. That's the white in the first picture, water droplets which scatter light.

Mind you, while I was poking around in your head looking for that image, I noticed a few other things you might want to get checked out
