Hurricane Katrina made landfall as a category 3 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.
Science and the Storms: the USGS Response to the Hurricanes of 2005
This report is designed to give a view of the immediate response of the USGS to four major hurricanes of 2005: Dennis, Katrina, Rita, and Wilma. Topics vary from flooding and water quality to landscape and ecosystem impacts, from geotechnical reconnaissance to analyzing the collapse of bridges and estimating the volume of debris.

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.
