Corps never pursued design problems...

New Orleans flooded because the levees failed. Now comes a story in today's Times-Picayune suggesting that the Corps of Engineers were aware of levee design problems as far back as 1990. While higher-ups raised red-flags somehow concerns were ignored.

While this article has technical engineering information that is beyond a lay-person like myself it does leave the impression that the flooding after Hurricane Katrina could have been avoided. Hopefully, something useful can be learned from this post-mortem.
