Coastal Change Hazards: Hurricanes and Extreme Storms

Hurricane Ike

Latest Response Activities

RESEARCH HIGHLIGHTS Lidar reveals coastal change on the Bolivar Peninsula, TX Before and after photo comparisons: Bolivar Peninsula, TX; Galveston, TX Post-storm photos: Oak Grove, LA to Quintana, TX

Hurricane Ike made landfall as Category 2 hurricane near Galveston, Texas, on September 13, 2008. The U.S. Geological Survey (USGS) Hurricanes and Extreme Storms Group is investigating coastal change caused by Hurricane Ike.

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

• Pre-storm photos (data collection by UNO, completed 09/10/2008)
• Initial assessment of potential coastal-change impacts (web post)

Post-landfall (approx. 3-5 days)

• Post-storm oblique aerial photography mission (data collection, completed 09/15/08)
• Post-storm airborne lidar topographic survey (data collection, completed 09/18/08)
• Quick-response aerial photos of impacted coast (web post)
• Pre- and post-storm photo comparisons (web post)

Post-landfall (approx. 2 weeks)

• Initial pre- and post-storm lidar 3D imagery of topography and coastal change (web post)
