Sorry but i don't think it is possible to damn off the MS even if you had already dug the diversion
You don't have to dam the entire river. The "Old" channel isn't going anywhere.

How would you propose to divert it without blocking the existing flow?

Hardly any of SE LA would even be here if the river had never changed courses.




Who knew us cajuns were made out of silt and semen.

The flow still flows. Just not where it used to.

As it was said on here a week or so ago, if that were to happen, I think the government and the oil cmopanies would spend billions to get it back diverted to its current course of flow.

So, let's say that this years incident will go peachy. Will they build anything in the future as more back-up? Can they build anything that would help?

It would be easily done during periods of low water just as described above.



The east bank is much higher than the west. You would have to dig a new Panama Canal through hilly country on the east side. If you try to go west with the diversion, you would be lower than the channel you are trying to restore, and you would have to pump water up somehow.

no one is talking about diverting the whole thing through a channel to the gulf

we are talking about a new channel parallel to the OR channel which would serve the same purpose

doubtful


this is a once in a lifetime event we are witnessing

they will likely just do a ton of inspections and rehab to repair any minor damage thats been done

But you still have to force the river to take this new channel.

not sure if serious


if you fork the river before this fork, it will go that way as gravity would be helping


it would make the old channel easier to dam

Normally I'd be inclined to agree with you here, but I'm not so sure that the drainage pattern changes humans have created don't add to these flood events. Destroying wetlands that used to capture runoff cannot help flooding events. Now that runoff that would have been held by a wetland drains off of a farm field and enters a small creek or bayou within a couple of days.
