This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a technique for storm surge forecasting. Storm surge is the water that is pushed toward the shore by the force of the winds swirling around the storm. This advancing surge combines with the normal tides to create the hurricane storm tide, which can increase the mean water level by almost 20 feet. Numerical modeling is an important tool used for storm surge forecast. Numerical model ADCIRC (Advanced Circulation model; Luettich et al, 1992) is used in this thesis for simulating hurricanes. A statistical technique, EST (Empirical Statistical Technique) is used to generate life cycle storm surge values from the simulated hurricanes. These two models have been applied to Freeport, TX. The thesis also compares the results with the model SLOSH (Sea, Lake, and Overland Surges from Hurricanes), which is currently used for evacuation and planning. The present approach of classifying hurricanes according to their maximum sustained winds is analyzed. This approach is not found to applicable in all the cases and more research needs to be done. An alternate approach is suggested for hurricane storm surge estimation.

This book was released on 1979 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Great Lakes Environmental Research Laboratory and the Techniques Development Laboratory have compared Lake Erie storm surge forecasts produced by a dynamical and a statistical method for several months in 1977 and 1978. The dynamical method yields much better forecasts at Buffalo and slightly better forecasts at Toledo.

This book was released on 1975 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical means are used to compute storm surges (meteorological tides) in a standard basin of constant slope, bounded by a straightline coast. All storm tracks in this study are constrained to lie parallel to the coast; the storm can lie at any distance from the coast and travel with any speed, but once set, the distance and speed are invariant with time. Two driving forces, wind stress and atmospheric pressure gradient, are used to generate surges; they are derived from an analytic wind profile. The model storm is described with two invariant parameters, storm size and difference between ambient and central pressure of the storm.

This book was released on 1974 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Weather Service (NWS) has developed a technique for forecasting extratropical storm surges along the northeast coast of the United States. The storm surge is caused mainly by the strong winds associated with extra-tropical storms over nearshore areas.

This book was released on 1980 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Federal services that minimize loss of life and property due to tropical hurricanes include forecasts and flood warnings. Because of the different concerns of these agencies their models have evolved in different ways and are applied with different input data, and apparent disparities have appeared. Evaluation was accomplished by having each modeling group separately exercise its models for selected past events and by comparing the model outputs with each other and with observed water elevations. Open-coast storm surge models were evaluated, then inland flooding models were evaluated using as input one of the open-coast model results. Each model tested included features that offered important advantages. Further, the models were continually evolving to include improved descriptions of the land and waters and of storms. No one model's predictions consistently gave better comparisons with observed data, however; and it is unlikely that one will be clearly better than the others for Corps purposes.

Available in PDF, EPUB and Kindle. Book excerpt: One of the greatest hazards from hurricanes is the flooding due to storm surge. Emergency managers traditionally plan for storm surge by looking at the worst possible impact and design their plans accordingly. This is a safe course of action, but can also be a wasted expense if the worst case does not occur. Risk-based planning is a way to incorporate the likelihood or probability of an impact occurring into emergency planning. With respect to storm surge, though, there is very little information regarding probability of occurrence. This research uses data from a commonly accepted storm surge model, SLOSH from the National Weather Service, to develop probabilities of impact. The process and products are prototypes utilizing data from the 2007 SLOSH model run for the New Orleans basin. Products developed include a map of probability, probabilities of exceedance, and a list of model storms that generate surge at given locations.

Available in PDF, EPUB and Kindle. Book excerpt: A bathystrophic storm surge numerical model was verified, using data of historical hurricanes at selected traverses on the Gulf of Mexico and the east coast, by calibrating 'coupled' values of wind and bottom stress coefficients in hydrodynamic equations for the numerical computation. These coefficients represented model calibration constants that included more than the physical effects of wind and seabed friction. Surge hydrographs were calculated and compared with observed or recorded surge hydrographs of: (a) Hurricane of 1949 at Galveston and Freeport, Texas; (b) Hurricane Carla at Galveston and Freeport, Texas; (c) Hurricane Audrey at Eugene Island, Louisiana; (d) Hurricane Camille at Biloxi, Mississippi; and (e) Hurricane Carol at Narragansett Pier, Rhode Island. Comparisons were made with theoretical results for several hypothetical storm surge problems for which analytical solutions could be obtained. Although reasonable empirical solutions were obtained by combining values of initial rise and of coefficients of bottom friction and wind stress, the significance, variation and interdependence of these parameters could not be determined adequately because of limited historical data. Extrapolation of empirically derived wind stress and bottom friction relationships, as determined from lower windspeeds, to extreme probable maximum conditions associated with the synthetic hurricanes, could not be conclusively verified. Because of the complexity of the problem, data limitations, and the variability of different factors entering the calibration process, correlation for all historical hurricanes at all traverses was difficult to obtain.
