Looking at the Impact of Hurricane Ivan on Florida Coasts

Ivan was just one of four strong hurricanes to directly hit Florida coasts within a 1-month period in 2004.

A new study has examined the poststorm impact and the short-term recovery from Ivan along a 200-km stretch of coast from Fort Walton Beach to St. George Island. The study is published in the latest issue of the Journal of Coastal Research.

Hurricane Ivan made landfall along the northwestern Florida and Alabama coast on September 16, 2004. It briefly reached Category 5 strength, persisting as a strong Category 4 hurricane in the Gulf of Mexico before being downgraded to a strong Category 3 at landfall by the U.S. National Hurricane Center.

A team of researchers from the University of South Florida conducted one prestorm and three poststorm beach-profile surveys to understand the morphological changes created by Ivan and also the poststorm recovery. Included in the assessment was an excavation of 46 trenches to study the characteristics and thickness of subaerial storm deposits.

Storm impact along barrier island coasts has been the subject of numerous studies. Because of the largely unpredictable nature of extreme storms like hurricanes, most studies concentrate on poststorm impact and behavior, whereas collection of prestorm data is typically not conducted, making it difficult to quantify the dramatic morphological impact of storms as well as poststorm recovery.

What the study found was apparent, and dramatic morphological and sedimentological impacts extended more than 300 km eastward from the center of the hurricane. Extensive inundation and overwash occurred within 100 km from the storm center at landfall. The highest elevation of beach erosion extended considerably above the measured storm-surge level, indicating that storm-wave setup and swash run-up played significant roles in controlling the elevation of beach erosion.

Beach recovery began immediately after the storm. Within 90 days, the berm crest recovered to its prestorm elevation, although it was now located 15 m landward.

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
