These levees needed a lot more than maintenance. Earthen dams -- even if they are capped with cement don't have the strength. They showed diagrams on FOX of what is happening and anyone who knows
about dams realizes that the pressure on these things is incomprehensible right now and they are being undermined from underneath as well as too much direct pressure on the sides. The Army Corp built huge
levees in Central California years ago and they, too, failed in a big flood... lucky that mostly farmland was in the path of those levee's."
Max pressure on a levee occurs when all the water is on one side.
True, but when the normally dry side of a levee is soaked, the integrity of the levee will be compromised. If the river levees are breached we would have an endless supply of water pouring into New Orleans. Equilibrium would occur when the "bowl" is filled to river-level and starts running OUT...............
