To the Library, Thanks.
Many thanks for your work- I'll link to it, and send it to everybody I know.
ping for later study
On the Rita Live thread, they are saying that FOX is reporting water "pouring into the 9th ward".
CoE is looking into it.
I'm glad you all are getting something out of this, and wish I could focus on it entirely right now, but there's this other hurricane....
wow, thanks for ping...
The color coding (G, Y, O, B) and the numbered arrows have been a great help, too.

The bottomline is that you cannot protect anything with a single level of levees. The Dutch know this and have concentric rings with low-lying farm lands that can flood without doing much damage if the outer rings (levees) fail. To protect New Orleans and surrounding Parishes they will need to give up some of the populated areas for spillways or take back more of the wetlands and lakes. Expecting ZERO failure is absurd.

Excellent.
It looks like large portions are just swampland, unfit for humans to reside.
They need 30 feet high flood walls, period.
It does not matter how high or how wonderful levees are at some point they all fail. NOLA can only be protected by having a layered defense and places for water to go if (er, when) you get a break.
That is correct.
Great work. Very informative.
Sorry. G, Y, O, R (Red for "breached")
Bump for later
Not sure if ya'll were on the original ping list, but you might find this interesting.
Great info, thanks!! One thing I have wondered about is.... why on earth do they even have such canals in the midst of a below-sea-level city lying in a prime floodplain and hurricane zone? Seems like they've created many miles of added vulnerabilities.... yes, I understand (presumably) the canals were created for additional transport to and from industrial areas, but in the rebuilding of NOLA that seems like a luxury they cannot afford -- shouldn't those canals be filled in now??? They can use rail links rather than water transport, I would hope, for such routes within the city....
Great research and summary! Thanks for the ping.

Probably the best and most soundly, exhaustively researched and pertinent assemblage yet to be found on Katrina, her effects, failed protection systems, and the timeline of events which transpired. This sequence covers the levees and the riverwalls in particular.
Kudos, hat tip and great work to Jeffers!
