Army researching ways to shore up levees before storms or floods overtop them

WorldNetDaily: Army tests 'super-levees':

"According to Wired News, the Army is testing so-called 'super levees,' which are designed to temporarily raise the height of levees to prevent them from being breached by rising floodwaters."

Interesting article about on-going Corps of Engineers studies of ways to add to levees in advance of expected storm/flood conditions.

I'd still like to know why it took so long to begin temporary repairs in New Orleans. I am hardly an expert, but I have helped to build some ponds and read some of the literature on the use of geotextiles and dredges and such.

Why was it not possible to work from boats and barges in Lake Pontchartrain to stretch geotextiles across the broken spots and use dredges to move material from the lake bottom onto the geotextile mats, building up a new earthen barrier in stages? Perhaps it would not have worked or would not have been faster than what they finally began to do, but it would have allowed some work to begin before land access to the breached areas was possible. Just a thought.
