Northeastern and mid-Atlantic United States are understudied from the perspective of hurricane vulnerability. In an attempt to fill this gap in research, this dissertation attempted to assess the hurricane vulnerability of the northeastern and mid- Atlantic United States through the construction of a Composite Hurricane Vulnerability Index (CHVI) for 184 counties extending from Maine to Virginia. The CHVI was computed by incorporating indicators of human vulnerability and physical exposure....
Show moreNortheastern and mid-Atlantic United States are understudied from the perspective of hurricane vulnerability. In an attempt to fill this gap in research, this dissertation attempted to assess the hurricane vulnerability of the northeastern and mid- Atlantic United States through the construction of a Composite Hurricane Vulnerability Index (CHVI) for 184 counties extending from Maine to Virginia. The CHVI was computed by incorporating indicators of human vulnerability and physical exposure. Human vulnerability was derived from demographic, social and economic characteristics whereas physical exposure was based on attributes of the natural and built up environments. The spatial distribution of the CHVI and its component indices were examined and analyzed to meet the research goals, which were a) to develop indices of human vulnerability, physical exposure and composite hurricane vulnerability for all counties; b) to assess vulnerability distribution in terms of population size, metropolitan status (metropolitan versus non metropolitan counties) and location (coastal versus inland counties); c) to identify the specific underlying causes of vulnerability; d) to identify the significant clusters and outliers of high vulnerability; and e) to examine overlaps between high human vulnerability and high physical exposure in the region. Results indicated high overall vulnerability for counties that were metropolitan and / or coastal. Vulnerability clusters and intersections pointed towards high vulnerability in the major cities along the northeastern megalopolis, in the Hampton Roads section of Virginia and in parts of Delmarva Peninsula. Evidence of relationship of population size, metropolitan status and location with vulnerability levels provides a new perspective to vulnerability assessment.

- Title
- Mapping urban growth in Boca Raton Florida, over a thirty year period.
- Creator
- Breary, Gillian., Charles E. Schmidt College of Science, Department of Geosciences
- Abstract/Description
-
The rapid increase of urban growth is a major issue for many regions around the world, which result in astounding loss in farmlands and increase in population densities. It important that urban growth be monitored as it will aid the local government in implementing the appropriate measures for a growing population. The city of Boca Raton, Florida, is the case study for this research. A multi-temporal analysis is done of five Landsat satellite images over a thirty year time period, 1973-2002....
Show moreThe rapid increase of urban growth is a major issue for many regions around the world, which result in astounding loss in farmlands and increase in population densities. It important that urban growth be monitored as it will aid the local government in implementing the appropriate measures for a growing population. The city of Boca Raton, Florida, is the case study for this research. A multi-temporal analysis is done of five Landsat satellite images over a thirty year time period, 1973-2002. Textural analysis was performed on each of the images, to delineate the urban areas. Three by-products resulted from the textural analysis: time series tinted overlays, dasymetric mapping and a series of animated maps, showing the movement of growth across the landscape through time. All the resulting products of the time series analysis were used to show the magnitude and direction of growth over time.
