Katrina: engineers say NOLA 9th Ward flooded by "huge wave"

On NPR today, David Kestenbaum reports that engineers and scientists are analyzing exactly how New Orleans flooded after Hurricane Katrina. In addition to reported breaks in the floodwalls, a major with the Army Corps of Engineers says he believes the hurricane probably created a 20-foot wall of water — what he calls a "tsunami effect." Henry Rodriguez, president of St. Bernard Parish, told Kestenbaum the first help he saw after the flooding came from another country — fifty Canadian mounties, on day two of the disaster. Link
