Speculation On The Barge's Role

Many locals blame the barge for the catastrophic inundation of the area. Some lawyers have blamed the barge, including its owners and the cement terminal that had moored the barge and which had the barge in its care, custody, and control at the time of the hurricane.

A week after the storm Army Corps of Engineers project manager Al Naomi gave his preliminary impression, saying, "One would think it's the barge that did it," and confirming that the barge striking the floodwalls would have "precipitated a tremendous collapse". However, in the preliminary report presented to Congress, experts say that the barge was drawn through an existing hole in the floodwall, and that it was the topping of the Industrial Canal floodwall, not the barge, that caused the break. The LSU report subsequently found that overtopping did not occur, rather, design failures precipited the levee failures.

By late 2007, several investigations were completed that included analysis of the question of whether the barge had a causative role in one or more of the failures in the floodwalls atop the Industrial Canal levees, or whether it came into the city from an already-existing breach. The investigators funded by the National Science Foundation—from the University of California at Berkeley—concluded that the barge went through an already-existing breach caused by foundation failure of the floodwall. Another group of investigators, funded by the State of Louisiana, came to the same conclusion. Finally, a $20 million study, funded by the Department of Defense/United States Army Corps of Engineers, blamed the Industrial Canal levee failures on overtopping of the floodwalls by the storm surge and resulting scour and undermining of the foundation -- not the barge.

There is also speculation that the barge may have caused the other nearby breaches in the Industrial Canal by striking the floodwalls on the other side before bouncing back and going all the way through the levee near the end of Prieur Street, although all the scientists and engineers who investigated the failures regard such speculation as dubious and without any evidentiary basis.
