News > New Information on New Orleans Floodwall Failures
Washington Post: Investigators Link Levee Failures to Design Flaws. The article mentions the soil problems noted earlier, but also notes an analysis of a problem created by a side outlet on the floodwall:
Three months before Katrina, Mashriqui told a room full of emergency managers that the outlet was a "critical and fundamental flaw" in the Corps' hurricane defenses, a "Trojan Horse" that could amplify storm surges 20 to 40 percent.
With the help of a supercomputer, Mashriqui has now concluded that the effect was even worse than he predicted.
