Later developments eventually extended to nearby Lake Pontchartrain, built upon fill to bring them above the average lake level. [29] This issue is addressed again in a study released in August 2015 by J. David Rogers et al., who concluded that a misinterpretation of the 1986 study occurred apparently because the Corps had draped a tarpaulin over the gap that formed between the bases of the deflecting sheet piles and the soil in which they were embedded, so they did not see the gap. "At 17th Street, the soil moved laterally, pushing entire wall sections with it. The only federally ordered study was convened and managed by the Army Corps of Engineers, the federal agency responsible for the flood protection's performance. In video … — First responders are battling rising water that is overtopping a back levee system that protects some parts of Plaquemines Parish from coastal flooding. Reasons for belief in these theories have been ascribed to the decision by city officials during the Great Mississippi Flood of 1927 to set off 30 tons of dynamite on the levee at Caernarvon, Louisiana which eased pressure on levees at New Orleans but flooded St. Bernard Parish, the Ninth Ward taking the brunt of the city's flooding during Hurricane Betsy, the general disenfranchisement of blacks and lower-class people, and the similarity of the sound of the levees collapsing to that of a bombing. The procedures for designing and constructing hurricane protection systems will have to be improved, and the designing organizations must upgrade their engineering capabilities. There must be independent peer reviews of future designs and construction.”[27], Preliminary investigations and evidence were presented before the U.S. Senate Committee on Homeland Security and Governmental Affairs on November 2, 2005, and generally confirmed the findings of the preliminary investigations.[28]. By December, seven of the actual piles had been pulled from the ground and measured. Flooding caused power outages and transportation failures throughout the city, making the emergency response to the storm even more difficult. – The Louisiana National Guard began repairing a levee breach at the Louisiana State Penitentiary in Angola, as one of several Innovative Readiness Training and Overseas Deployment Training projects planned throughout the year, Jan. 15. “I don’t think anybody anticipated the breach of the levees,” Bush said on September 1, 2005, during an interview with Good Morning America. For years before Hurricane Katrina, scientists, journalists and emergency officials had been worrying about what could happen if a major hurricane were to hit New Orleans. 41K Views. § 702c. Even with this vast expenditure, experts continue to question whether New Orleans is truly safe from the next big storm. [12] The shear strength of this peat was found to be very low and it had a high water content. A forensic engineering team from the Louisiana State University, using sonar, showed that at one point near the 17th Street Canal breach, the piling extends just 10 feet (3.0 m) below sea level, 7 feet (2.1 m) shallower than the Corps of Engineers had maintained. By the time Katrina arrived, New Orleans lay at an average of six feet below sea level, with some neighborhoods even lower than that. In four cases the structures failed catastrophically prior to water reaching design elevations. Flooding was limited to non-existent in most parts of the southeast but down at the tip of The Boot we did have a levee breach. Dr. Breached Levee Statement.

But the levee failures weren’t a complete surprise. River water poured through the breach and began to rush to the south, soon joined by floodwaters caused by a break in a Bayou des Glaises levee to the north of St. Landry, in Avoyelles Parish. CE Database subject headings: Levees; Failures; Risk management; Louisiana. Throughout the area, levees and flood walls failed or were breached in more than 50 locations. [6] An estimated 66% to 75% of the city was now under water. A preliminary report released on November 2, 2005, carried out by independent investigators from the University of California, Berkeley and the American Society of Civil Engineers (ASCE) stated that many New Orleans levee and flood wall failures occurred at weak-link junctions where different levee or wall sections joined together. Some homes and other buildings are completely submerged, while the roofs of others appear to float above the murky water.
