re: Miss River Flood Thread 2016, river back on the rise again.......

SOggy levees and a rising angry river and you also have to take into account the barges and other marine equipment all over the river that could break and crash a hole into a levee.

Errett says the Corps is already preparing for flooding in the New Orleans area.

Key flood locations identified by the ACE which have the greatest potential to fail per post 2011 Flood report:
Post 2011 Flood Damage report by USACE

1. Baton Rouge Front
2. Duncan Point
Duncan Point is an area of historic seepage. A massive aquifer in excess of 300 feet deep exists beneath the levee overlain by a thin blanket of confining material. This blanket has been ruptured and the situation continued to deteriorate with successive high water events. The area was previously a historic sand boil; but in 2010, a stabilization berm was constructed. As a result, the seepage moved from the berm to an area north along the protected side toe of the levee. There was extensive seepage at this site to include a sand boil at levee toe and soft, spongy conditions one-third up the levee slope, requiring extensive flood-fight efforts. A temporary, berm was constructed using 12,000 sandbags to reduce seepage in the most critical reach of the site. Adjacent highway experienced spongy conditions requiring
closure.

3. Chalmette Seepage (fixed)
4. Jackson Barracks Slope Paving (NO SWB purportedly fixed)
5. Old River Seepage
6. Blackhawk Slide
7. Audubon Seepage (by John James Audubon Bridge)
8. Pointe Coupee Seepage
9. Point Pleasant Seepage
10. Algiers Seepage
11. West of Berwick
12. Bayou Chene
13. Old River Control Complex
