Abstract:
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.
