patience on morganza
Posted on 5/13/11 at 1:54 pm
Posted on 5/13/11 at 1:54 pm
please, everyone wanting morganza open now or tonight or in the morning . . . there is a reason they wait and it's not quite so obvious, namely: THEY WANT SO MUCH POWER BEHIND THE RELEASE THAT SAND AND SILT DON'T CLOG THE FIRST FIVE MILES OF THE SPILLWAY. in a slow-mo release, the great muddies' sediment settles out rather quickly, reducing the force of all that comes after it. a niagra style release pushes all that silt for miles and miles before it settles.
the longer they wait, within reason, the more the spillway can handle if called upon. the RUSH of water pushes the stiffling sediment way out into the swamp and makes the path of all new waters easier . ..

Your logic......… we're not having it.

So they are gonna wait until there is so much pressure built up behind the Morganza that it could potentially damage the structure and lose it altogether for the sake of sediment?
Are you postulating or do you know something no one else does.

based on the 61+ feet of water I think the pressure behind it will be just fine. It may spray all the way to texas when they open it.

Sounds like the river needs to go potty.

does river water contain sediment within it? does it fall out quicker when the waters are slow or torrential . ..logic and common sense support my position

Someone slept at a Holiday Inn last night.

so with the river at 61 feet it will only trickle through when opened....I see.

Hmmm. Not so sure.
They are pulling water off the top of a very wide river. It is not going to be as turbid.
It is going to be hauling arse through a very wide, very deep area for a very long time. I don't know that a foot or two in the starting height will make any difference at all.

Actually when they did the Bonnet Carrie, they opened just 28 Bays at first, to allow the water to slowly fill in to prevent washout. (there is a surface Road, right in front of the structure).
I think letting the water in too fast, tears the ground up. Plus the way the Spillway is designed, you open one gate at a time. So there will never be a colossal wave of water, all at one time.

not at all . ..it's just that when they open it, they want the rushing waters to solve a basic hydrodynamical problem for them and save those downstream of both sides of morganza to every extent possible . ..make nature help instead of attack only

It's usually pretty easy to tell the folks on here who are talking out their asses from the folks who know what they're talking about.
This dude seems to know what he's talking about, from what I can tell at least.

I think each gate lets through about 290,000 cubic feet of water per minute. So I guess it depends on the definition of colossal.

basic hydrodynamical problem

I thought they would be opening the bays in stages to ensure that washout didn't occur. Moreover, i think they will only be opening a maximum of 50% of the bays. I don't think the sediment blockage will be a problem as long as they stick to the plan of opening the bays on a structured schedule.

So he can list you as a character reference...strike one.

The entire Morganza structure is 3/4 of a mile wide. Even if they opened it wide,it immediately flows into a basin that is four to five miles wide. It is going to drop sediment no matter how fast you flow it.

I'm going with the judge on this one

CNBC has yet to mention this.
