Hurricane Katrina - Documentation of Coastal Change

Science Center Objects

Aerial video, still photography, and laser altimetry surveys show the nature, magnitude, and spatial variability of coastal changes such as beach erosion, overwash deposition, and island breaching.

Hurricane Katrina made landfall as a category 3 storm in Plaquemines Parish, Louisiana, on August 29, 2005. The USGS, NASA, U.S. Army Corps of Engineers, and the University of New Orleans cooperated 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 were used to further refine predictive models of coastal impacts from severe storms and were made available to local, state, and federal agencies for purposes of disaster recovery and erosion mitigation.
