I'm genuinely curious what happens if the forecast crest of 43' in BR occurs (which we have every reason to believe it will and this is by no means record levels) and then a 4' section of levee washes away sometime over night due to the increased pressure on the levee at a time when it's saturated from heavy rain since November. Where would all that water spread out to? It would eventually (within a couple days I'm sure) flow into the Comite and Amite Rivers, flooding Livingston, Ascension and St. James parishes pretty badly as well.

Just to put it into perspective: The 2016 flood was caused by about 7.1 trillion gallons of water dropped in 3 days.

The Mississippi River flows about 700,000 cubic feet per second at max, which is about 5.25 million gallons per second. At that rate, it would take 1,350,000 seconds to put the same amount of water heading toward the Amite and Comite. That would take 15.5 days to equal the same amount of water, and that's if the Mississippi goes completely dry downstream of BR because it's busy monkeyfricking us.

The short answer is I have no fricking clue.
