A Generalized Accelerated Failure Time Model To Predict Restoration Time From Power Outages, Tasnuba Binte Jamal
A Generalized Accelerated Failure Time Model To Predict Restoration Time From Power Outages, Tasnuba Binte Jamal
Graduate Thesis and Dissertation 2023-2024
Major disasters such as wildfire, tornado, hurricane, tropical storm, flooding cause disruptions in infrastructure systems such as power outage, disruption to water supply system, wastewater management, telecommunication failures, and transportation facilities. Disruptions in electricity infrastructures have negative impacts on sectors throughout a region, including education, medical services, financial, and recreation sectors. In this study, we introduce a novel approach to investigate the factors which can be associated with longer restoration time of power service after a hurricane. Considering restoration time as the dependent variable and utilizing a comprehensive set of county-level data, we have estimated a Generalized Accelerated Failure Time …
Impact Of Climate Change On Storms And Coastal Morphodynamics, Kelsey Perez
Impact Of Climate Change On Storms And Coastal Morphodynamics, Kelsey Perez
Honors Undergraduate Theses
Storms have been impacting coastal morphodynamics directly due to its intensifying effects over the years. Climate change has caused an exponential impact on storms and therefore morphodynamic changes in the coasts. A specific land that has constantly been threatened is Dauphin Island, a barrier island in Alabama. Over time, it has experienced a total land loss of 100 ft of shoreline over the past of 3 decades and an overall 16% land loss of the island due to the intensifying effects of storms due to a changing climate. In this study, we use Hurricane Ivan as an example. In order …
An Improved Ocean Vector Winds Retrieval Approach Using C- And Ku-Band Scatterometer And Multi-Frequency Microwave Radiometer Measurements, Suleiman Odeh Alsweiss
An Improved Ocean Vector Winds Retrieval Approach Using C- And Ku-Band Scatterometer And Multi-Frequency Microwave Radiometer Measurements, Suleiman Odeh Alsweiss
Electronic Theses and Dissertations
This dissertation will specifically address the issue of improving the quality of satellite scatterometer retrieved ocean surface vector winds (OVW), especially in the presence of strong rain associated with tropical cyclones. A novel active/passive OVW retrieval algorithm is developed that corrects Ku-band scatterometer measurements for rain effects and then uses them to retrieve accurate OVW. The rain correction procedure makes use of independent information available from collocated multi-frequency passive microwave observations provided by a companion sensor and also from simultaneous C-band scatterometer measurements. The synergy of these active and passive measurements enables improved correction for rain effects, which enhances the …
Computational Hurricane Hazard Analysis A Performance Based Engineering View, Christopher Michael Vanek
Computational Hurricane Hazard Analysis A Performance Based Engineering View, Christopher Michael Vanek
Electronic Theses and Dissertations
Widespread structural damage to critical facilities such as levees, buildings, dams and bridges during hurricanes has exemplified the need to consider multiple hazards associated with hurricanes as well as the potential for unacceptable levels of performance even if failure is not observed. These inadequate standards warrant the use of more accurate methods to describe the anticipated structural response, and damage for extreme events often termed performance based engineering (PBE). Therefore PBE was extended into the field of hurricane engineering in this study. Application of performance-based principles involves collection of the numerous hazards data from sources such as historical records, laboratory …
The Response Of A General Circulation Climate Model Tohigh Latitude Freshwater Forcing In The Atlantic Basinwith Respect Totropi, Victor Paulis
The Response Of A General Circulation Climate Model Tohigh Latitude Freshwater Forcing In The Atlantic Basinwith Respect Totropi, Victor Paulis
Electronic Theses and Dissertations
The current cycle of climate change along with increases in hurricane activity, changing precipitation patterns, glacial melt, and other extremes of weather has led to interest and research into the global correlation or teleconnection between these events. Examination of historical climate records, proxies and observations is leading to formulation of hypotheses of climate dynamics with modeling and simulation being used to test these hypotheses as well as making projections. Ocean currents are believed to be an important factor in climate change with thermohaline circulation (THC) fluctuations being implicated in past cycles of abrupt change. Freshwater water discharge into high-latitude oceans …
Optimization Models For Emergency Relief Shelter Planning For Anticipated Hurricane Events, Abeer Tarief Sharawi
Optimization Models For Emergency Relief Shelter Planning For Anticipated Hurricane Events, Abeer Tarief Sharawi
Electronic Theses and Dissertations
Natural disasters, specifically hurricanes, can cause catastrophic loss of life and property. In recent years, the United States has endured significant losses due to a series of devastating hurricanes (e.g., Hurricanes Charley and Ivan in 2004, and Hurricanes Katrina and Wilma in 2005). Several Federal authorities report that there are weaknesses in the emergency and disaster planning and response models that are currently employed in practice, thus creating a need for better decision models in emergency situations. The current models not only lack fast communication with emergency responders and the public, but are also inadequate for advising the pre-positioning of …
The Effect Of Tidal Inlets On Open Coast Storm Surge Hydrographs: A Case Study Of Hurricane Ivan (2004), Michael Salisbury
The Effect Of Tidal Inlets On Open Coast Storm Surge Hydrographs: A Case Study Of Hurricane Ivan (2004), Michael Salisbury
Electronic Theses and Dissertations
Florida's Department of Transportation requires design storm tide hydrographs for coastal waters surrounding tidal inlets along the coast of Florida. These hydrographs are used as open ocean boundary conditions for local bridge scour models. At present, very little information is available on the effect that tidal inlets have on these open coast storm tide hydrographs. Furthermore, current modeling practice enforces a single design hydrograph along the open coast boundary for bridge scour models. This thesis expands on these concepts and provides a more fundamental understanding on both of these modeling areas. A numerical parameter study is undertaken to elucidate the …
