Hurricane Gustav: Observations of Coastal Change

OFR 2009-1279As part of the National Assessment, observations were collected to measure morphological changes associated with Hurricane Gustav, which made landfall near Cocodrie, Louisiana, on September 1, 2008. Methods of observation included oblique aerial photography, airborne topographic surveys, and ground-based topographic surveys. This report documents these data-collection efforts and presents qualitative and quantitative descriptions of hurricane-induced changes to the shoreline, beaches, dunes, and infrastructure in the region that was heavily impacted by Hurricane Gustav.

Coastal Change on Gulf Islands National Seashore during Hurricane Gustav: West Ship, East Ship, Horn, and Petit Bois Islands

OFR 20101090The USGS has processed, analyzed, and interpreted pre- and post-Hurricane-Gustav lidar topographic data for West Ship, East Ship, Horn, and Petit Bois. These data and analyses can be used to better assess the storm vulnerability of portions of Gulf Islands National Seashore by characterizing the magnitude and spatial variability of hurricane-induced coastal changes, such as shoreline retreat, dune erosion, and beach volume change.

Hurricane Gustav moved ashore east of the Isles Dernieres on September 1, 2008, making landfall near Cocodrie, LA, as a Category 2 storm. The U.S. Geological Survey (USGS) Hurricanes and Extreme Storms Group investigated coastal change that occurred along Louisiana's sandy beaches as a result of Hurricane Gustav.

Aerial video, still photography, and laser altimetry surveys of post-storm beach conditions were collected for comparison with earlier data. The comparisons 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.

Response Activities

Pre-landfall

Post-landfall (approx. 3-5 days)
