Will Katrina cause the Mississippi to change course? [View All]

[Silverhair]

For those that don't know, the lower Mississippi changes course about ever 400 years. At the time New Orleans was settled the river had just changed it's course. Now it is trying to change again and take a more direct, more southerly, route to the Gulf. The "Old River Control Structure"was built by the Corps of Engineers to stop that from happening.

When I was living in New Orleans in the late 70's the Engineers were warning that the structure had been weakened, could not be repaired, and that the Mississipppi would one day break free of the structure and take a new course, leaving New Orleans. They warned that the triggering event would likely be a really big flood.

I did some googling to see what I could find, but all I came up with on a short search said nothing about that.

Does anybody know much about this topic? If so, could Katrina cause the Mississippi to change course?
