If that's the timetable the majority of the wildlife should survive.....Quote:

Man... That is Wild. Are we at the point of inevitability?Quote:

Add to the Spector of hurricane season dumping water and this becomes beyond fathom.
Except for rabbits and young turkey poults, most wildlife will be able to escape although stressed being forced from its habitat.
........So what aboutAbbeville? Vermilion River? What aboutNO?Quote:

It certainly would be a sight to see for sure. I would be on the East bank across from Knox Landing to get a good view although you probably won't see too much. If you live on the west bank of the river you might have to take I-20 to get back home. Depending on where you live, you may not have a home to go back to. Probably the best place to see it would be on TV at your home. That is, unless you lived near or in the basin or in Morgan City. Then I would be getting my butt out of there looking for another place to live.
Water is lazy it will seek the line of least resistance. The ORCS spans from mile 311 to 316 on the Mississippi river (That is 311 miles to 316 miles from the mouth of the river at the gulf of Mexico). The Atchafalaya river is a route of about 150 miles to the gulf of Mexico. That is about half the distance which results in twice the slope of the water surface elevation. Let's see now, which one do you think it will take.
The question in my mind is, which one will be first, Yellowstone blowing or the Mississippi river diverting. Both events would be of biblical proportions and would illustrate the folly of man thinking that they have control or influence over any of this crap.

Abbeville probably ok, Vermilion River, probably ok, New Orleans will be left with no fresh water supply as the Gulf of Mexico will back up into the evacuated channel of what would then be the new old river. The high salt levels of the water will kill most of the vegetation in the area and coastal erosion will accelerate. The oyster fishermen will be happy. The problem would be the only people to sell the oysters to would be on the north shore and Mississippi. New Orleans would be even more unlivable than it is now which would result in a mass migration of people out of the area because of lack of fresh water. Baton Rouge would have a similar problem in that they are already having to fight salt water intrusion due to the high pumping rates of water out of the Baton Rouge aquifer. We will still have LSU A&M football on Saturday nights to look forward to HA HA.Quote:

1. The basic idea is that there would be a sand build up south of the Old River Control Structure, causing a clog, which allows the water to rise over the ORCS into Outflow channel and eventually the Atchafalaya?
2. When the water does divert to the Atchafalaya, what happens to the freshwater that is already in the river between the OCRS clog and the Gulf? It eventually will be inundated with salt water coming up from the Gulf of Mexico?
3. I understand that the people of Morgan City would be screwed, but why would New Orleans and Houma be forced to evacuate, and then why would thy have three weeks?
No drinking water for starters, salt water would take away their source.Quote:

Could you or someone please repost the video with Dr. Xu? I can’t find it...

Silt is kept in suspension at velocities of greater than 2 feet per second (Self cleansing velocity). Velocity at the top of the stream is greater than the bottom because of fiction with the earthen channel and as you get closer to the gulf of Mexico salt water ( salt water is heavier than fresh water. the fresh water stays on the top of the stream flow). Given that the salt water is there it slows down the water below self cleansing and the silt load drops causing the formation of sand bars. The diversion of water into the Atchafalaya is about 30% of the Mississippi but it is decant water (water from the top with a lighter silt load). So, more silt is sent through to Baton Rouge/ new Orleans than is sent do the Atchafalaya. The silt diversion is not 30% and is very difficult to predict as discussed by Professor Einstein. There is a certain amount of silt diverted as evidenced by the two mini deltas formed at the Wax Lake outlet and Atchafalaya river delta. see below.Quote:

Salt (NaCl) dissociates into Sodium ions and Chloride ions and cannot be removed by the methods used to purify the river water. They would need to totally rebuild their water plants to some form of ion exchange process or reverse osmosis that would be very expensive and take a tremendous amount of time to implement. I would think that most everybody would get pretty thirsty before they could finish. Not to mention meeting the various health standards that are required to be met.Quote:
