John Christian, an independent geotechnical engineer and member of the National Research Council commission investigating Hurricane Katrina and its aftermath, presents the results of his geological research on the causes of Katrina's devastating physical impact on New Orleans and the Gulf Coast. Christian also provides an overview of the work done by four other independent commissions, including the Army Corps of Engineers and researchers at the University of California, with a particular focus on why the levies of New Orleans failed.
