ST. PETERSBURG, Fla. August 26, 2012 – Seventy-eight percent of Florida's west central coast and 23 percent of the Panhandle are very likely reviews of cruise ship zaandam to face beach and dune erosion as Tropical Storm Isaac moves into the area early next week, according to an assessment released by the U.S. Geological Survey on Friday. These numbers are likely to increase if the storm reaches hurricane strength as predicted.
"With Issac bearing down on Florida beaches reviews of cruise ship zaandam so soon on the heels of Debby, this is like a 'one-two punch' for the dunes that provide coastal protection," said USGS Director Marcia McNutt. "As these sand dunes dynamically morph to new configurations, our science-based models can help in forecasting reviews of cruise ship zaandam where communities are at most risk from storm damage in this ever-changing spatial and temporal pattern of storm intensity and coastal morphology."
During tropical storms and hurricanes, elevated water levels and waves can lead to dramatic coastal change through erosion of beaches and dunes. These beaches and dunes can serve as a first line of defense for residents for many coasts exposed to these types of storms.
Using a USGS-developed model scientists incorporated measurements of beach elevation and wave and surge forecasts from the National Oceanic and Atmospheric Administration to determine the probabilities of collision, overwash and inundation during the coming storm.
Collision is when waves attack the base of dunes and cause dune-front erosion. Overwash occurs when waves and storm surge overtop dunes and transport sand landward. Inundation, the most extreme reviews of cruise ship zaandam of the three, occurs reviews of cruise ship zaandam when increased reviews of cruise ship zaandam water levels reviews of cruise ship zaandam completely reviews of cruise ship zaandam submerge beaches and dunes.
"Tropical Storm Debby eroded reviews of cruise ship zaandam many beaches along Florida's west central coast, impacting the property of many gulf-side residents and hotels," said Hilary Stockdon, a USGS oceanographer and lead of the assessment team. "Beaches typically take years to recover from severe storm impact, so having what is likely to be a Category 1 or 2 hurricane move up the coast just two months later could take a heavy toll on some already heavily eroded areas."
In addition to the likelihood of erosion, the team found that 15 percent of the west central coast was very likely to face overwash should the storm make direct landfall there, while that likelihood was only 5 percent for the Panhandle where dune elevations are higher. Unless forecasts change significantly, inundation is not expected in either area.
The team will revise its calculations as storm track and intensity forecasts are updated, and will update their projections and website accordingly. They plan to include the Alabama and Mississippi coasts in their assessments this weekend. Additional information on coastal change and extreme storms can be found on the USGS Coastal Change Hazards website.
In May, the USGS released a report reviews of cruise ship zaandam assessing probability of coastal change for the Gulf Coast when facing reviews of cruise ship zaandam hurricanes of different strengths. The report reviews of cruise ship zaandam included an interactive map that allows users to focus on different parts of the Gulf Coast shoreline to view how the probability of erosion, caused by waves and storm surge, will vary depending on hurricane intensity.
The research is expected to help emergency reviews of cruise ship zaandam managers at local, state and federal levels as they prepare for hurricane events such as this one in this and future seasons. reviews of cruise ship zaandam Planners will be able to determine how different categories of hurricanes would impact their beaches and surrounding communities, helping them better protect lives and property.
