Hydrologic Modeling A SIMULATION OF THE HURRICANE CHARLEY STORM SURGE AND ITS BREACH OF NORTH CAPTIVA ISLAND
نویسندگان
چکیده
A high resolution, three-dimensional numerical circulation model with flooding and drying capabilities is used to simulate the Hurricane Charley storm surge in the Charlotte Harbor vicinity. The model-simulated surge is in sufficiently good agreement with observations at four stations for which data exist to allow us to use the model to explain the surge evolution and to account for the inlet breach that occurred at North Captiva Island. Despite Charley being a Saffir-Simpson category 4 hurricane the surge was only of nominal magnitude and hence the damage, while severe, was primarily windinduced. We explain the relatively small surge on the basis of the direction and speed of approach, the point of landfall to the south of Boca Grande Pass and subsequent translation up the estuary axis, and the collapse of the eye radius as the storm came ashore. These inferences are based on lessons learned from hypothetical hurricane storm surge simulations for Tampa Bay. Under other approach scenarios the potential for hurricane storm surge in the Charlotte Harbor may be catastrophic.

Modeling and Simulation of Tsunami and Storm Surge Hydrodynamic Loads on Coastal Bridge Structures
Bridge structures along the coasts are often subjected to hydrodynamics loads of various forms and intensities. The most dramatic loads are those due to tsunamis and storm surges as vividly demonstrated by images of the Dec. 2004 Indian Ocean Tsunami and the Sept. 2005 Katrina Hurricane in the Gulf of Mexico. Other loads include wave impact, current induced scour, and floating debris impact. Th...
متن کاملCircular Conditional Autoregressive Modeling of Vector Fields.
As hurricanes approach landfall, there are several hazards for which coastal populations must be prepared. Damaging winds, torrential rains, and tornadoes play havoc with both the coast and inland areas; but, the biggest seaside menace to life and property is the storm surge. Wind fields are used as the primary forcing for the numerical forecasts of the coastal ocean response to hurricane force...

Hurricanes are causing increasing damage to many coastal regions worldwide1,2. O shore wind turbines can provide substantial clean electricity year-round, but can they alsomitigate hurricane damage while avoiding damage to themselves? This study uses an advanced climate–weather computer model that correctly treats the energy extraction of wind turbines3,4 to examine this question. It finds that...
