​Hurricane Katrina caused great destruction on the city of Biloxi, Mississippi, destroying homes, the civil infrastructure, and commercial buildings often hundreds of meters onshore. Geotechnical components fared relatively well and the evidence of erosion-induced failures is scarce. Structural failures affected both small dwellings and large systems such as bridges, casino barges, and storage tanks. The data collected as part of this study documents these cases and permit the evaluation of failure mechanisms. Most failures were produced by the combined effects of the storm surge and wave action.
