Abstract
Hurricane Dennis made landfall as a Category 3 storm on Santa Rosa Island in the Florida Panhandle on July 10, 2005. Exposed to some of the strongest winds, Santa Rosa Island suffered erosion, as well as severe overwash. A storm surge of 2 m was recorded near Navarre Beach.
The U.S. Geological Survey (USGS) and U.S. Army Corps of Engineers (USACE) are collaborating in a research project investigating coastal change that occurred as a result of Hurricane Dennis. The USGS acquired still oblique aerial photography both before and after hurricane landfall to better understand the impacts of extreme storms on coastal environments. On Tuesday, July 12, 2005, scientists conducted an aerial photographic survey of Santa Rosa Island, Florida, that was impacted by Hurricane Dennis.
The photographs were compared to pre-Dennis photographs taken in July 2001 and after the landfall of Hurricane Ivan in September 2004 to illustrate extreme coastal change. On Santa Rosa Island, the storm eroded dunes and beaches, and overwashed roads. In Navarre Beach, parking lots and roads were covered with sand and dune walkovers damaged or destroyed.
