Hurricane Katrina made landfall as a category 4 storm in Plaquemines Parish, LA on August 29, 2005. The U.S. Geological Survey (USGS), NASA, the U.S. Army Corps of Engineers, and the University of New Orleans are cooperating in a research project investigating coastal change that occurred as a result of Hurricane Katrina.

Aerial video, still photography, and laser altimetry surveys of post-storm beach conditions were collected August 31 and September 1, 2005 for comparison with earlier data. The comparisons will show the nature, magnitude, and spatial variability of coastal changes such as beach erosion, overwash deposition, and island breaching. These data will also be used to further refine predictive models of coastal impacts from severe storms. The data are being made available to local, state, and federal agencies for purposes of disaster recovery and erosion mitigation.
