Anthropogenic Influences On Sedimentation In The Chicken Creek Watershed Of South Carolina, Tyler L. Dearman

Theses and Dissertations

Anthropogeomorphic changes in response to destructive agricultural practices followed the arrival of European settlers into the Americas. The southeastern Piedmont physiographic region of the USA was severely affected by erosion and sedimentation following settlement in the 1700s and farming up through the 1930s. Deep floodplain aggradation formed uninterrupted alluvial deposits that extended many km. This research examines anthropogenic impacts of land-use change on valley bottom sedimentation in the Chicken Creek Watershed of South Carolina. Abrupt contacts between pre-settlement floodplain soils and a thick overburden of legacy sediment are common throughout the two-km study reach and provide clear evidence of extensive …

Everyday Occupations: Traffic, Hazards, And Mobility In The West Bank, Alice Arnold

Theses and Dissertations

Mobility in the West Bank is inherently tied to the Israeli military occupation. Each new stage of the decades old conflict comes with new implications for the way Palestinians move around the West Bank. The past years have seen a transition during which the severe mobility restrictions that constituted the closure policy of the second intifada eased and intercity travel has increased. In this study I examine day-to-day experiences of mobility in the West Bank in the post-closure period. In doing so I highlight the ways in which routine experiences of mobility, those with traffic, road hazards, and infrastructure, bring …

Internal Gravity Wave Detection During The 21 August 2017 Total Solar Eclipse, Michael J.W. Stewart

Theses and Dissertations

Total solar eclipses supply both visual captivation and a controlled meteorological experiment through a sudden decrease in solar radiation. However, along with commonly expected changes in weather conditions, prior research suggests an adjustment of atmospheric dynamics caused by both a decrease in local incident solar radiation and the Moon’s sweeping shadow across the Earth at supersonic speed. The result is the potential production of internal gravity waves, which transfer both energy and momentum vertically to and from the upper levels of the atmosphere. A series of radiosondes were launched before, during, and after the 21 August 2017 eclipse in Batesburg, …

Analysis Of Evacuation Behaviors And Departure Timing For October 2016’S Hurricane Matthew, Erika O. Pham

Theses and Dissertations

During a hurricane, an individual’s risk perception does not remain static. Spatial and temporal variations of a hurricane will shift perceptions of risk, and complicating this dynamic are information-seeking processes increasingly reliant on the individual’s self-motivated interpretation of information sources. Initial evacuation resistance or willingness could change even after evacuations are ordered, affecting evacuation preferences and departure times. Because Hurricane Matthew’s continually shifting track had virtually nonstop coverage, evacuation decisions were also being modified as residents either grew more or less certain of their safety.

This research investigates the evacuation behaviors associated with Hurricane Matthew in October of 2016. It …

Catchment Hydrology In The Anthropocene: Impacts Of Land-Use And Climate Change On Stormwater Runoff, Chen-Ling Jenny Hung

The Community Rating System: Assessing Indicators Of Community Participation, A Dasymetric And Sovi Approach, Zachary P. Landis

Theses and Dissertations

The National Flood Insurance Program (NFIP) was established to provide affordable insurance to property owners and encourage communities to adopt and enforce floodplain management, primarily through the Community Rating System (CRS). The CRS awards points to communities for adopting a variety of activities in support of floodplain management. One area of interest in the CRS program is understanding differences in the types of communities participating and the degree of their participation. Research on the NFIP’s CRS tends to focus on community program participation in reducing flood losses and indicators of participation. Much of this research was performed prior to 2013 …

Representing The Relationships Between Field Collected Carbon Exchanges And Surface Reflectance Using Geospatial And Satellite-Based Techniques, Alexandria G. Mccombs

Theses and Dissertations

Carbon exchanges between the atmosphere and the land surface vary in space and time, and are highly dependent on land cover type. It is important to quantify these exchanges to understand how landscapes affect the carbon budget, which will have a significant impact on future climate change and will inform climate change projections. However, how do you represent regional carbon exchanges from a single meteorological station? A single observing station will represent a limited area around the station, but each individual observation will sample a different physical land area in time due to varying wind speeds, wind direction, and atmospheric …

The Role Of Weather In The Social And Economic Lives Of Plantation Owners In Antebellum Beaufort District, South Carolina, Jennifer A. Simmons

Theses and Dissertations

Weather can determine social, agricultural, and economic impacts on a society. There has been a lot of contemporary research on adaptation and experiences in severe weather events. However, there is a lack of historical research. This study uses primary sources, such as journals, newspapers, and maps, to look into the impact that weather has on people during a study time. Primary sources, like Thomas Chaplin’s Tombee Plantation Journal, provide more than a physical description of the event that occurred. These historical sources present various perspectives, such as personal and emotional, of people in South Carolina’s Beaufort District and its sea …

Urban Accessibility Measurement And Visualization — A Big Data Approach, Yuqin Jiang

Theses and Dissertations

Accessibility measurement has always been an important question in different areas including transportation, urban planning, politics, and sociology. However, how to measure transportation accessibility in different areas have been limited to data availability and technology. Recently, with increasing availability in public transportation data, we found a gap between current methods and large volume of data now available. This thesis developed a new method to measure multi-mode transportation data, including taxi, bus, and subway. Based on this measurement, we can visualize and understand the spatiotemporal patterns of accessibility in New York City (NYC). With historical travel records and public transit schedule, …

Climate Change (Mal)Adaptation As Governmentality: The Case Of The Ada Sea Defense System In The Volta River Delta Of Ghana, Kwame Ntiri Owusu-Daaku

Theses and Dissertations

River deltas are complex natural environments that represent a confluence of many physical, biological and human processes vulnerable to the impacts of climate change. The likely biophysical impacts of climate change on deltas have received substantial attention. However, relatively little attention has been paid to the ways in which the different stakeholders of deltaic environments frame the vulnerability of residents of deltas to climate change. The Volta River Delta (VRD) of Ghana is a compelling site in which to conduct such an examination because of the clear climaterelated changes taking place in the Delta, and the fact that like many …

Cocoa And Carbon: Remedying Forest Governance Through Community Participation In A Redd+Pilot In Ghana, Manali Baruah

Theses and Dissertations

Global loss and degradation of forests are well documented, and the potential role of forests in climate change mitigation is widely recognized. While forests are key to human well-being, forest resource management in the developing world is fraught with governance challenges. Despite policy discourses that emphasize the importance of local participation in the management of forest resources, it is rarely practiced. Many national governments and non-governmental organizations have set up efforts around the collaborative management of forest resources with local communities to tackle forest loss. However, the operationalization of participatory principles and the effectiveness of these collaborative initiatives are not …

Contesting The Generic Refugee: Siv Identity, Community, And Agency During Resettlement, Benjamin J. Sylvester

Theses and Dissertations

This thesis examines the complexity of identity and community formation by Special Immigrant Visa (SIV) holders during resettlement in Columbia, South Carolina. It explores the ways in which identities coalesce around various themes, such as religion, gender, and military service, how these identities serve to create, expand, and claim membership in communities, and how SIVs exercise agency throughout these processes. Through semi-structured interviews with 9 SIVs in Columbia, SC, this qualitative study highlights the unique, highly individualized ways in which a select group of refugees experience resettlement, how they negotiate their placement within socio-economic hierarchies, and exercise agency to obtain …

Spatial Optimization Methods And System For Redistricting Problems, Hai Jin

Theses and Dissertations

Redistricting is the process of dividing space into districts or zones while optimizing a set of spatial criteria under certain constraints. Example applications of redistricting include political redistricting, school redistricting, business service planning, and city management, among many others. Redistricting is a mission-critical component in operating governments and businesses alike. In research fields, redistricting (or region building) are also widely used, such as climate zoning, traffic zone analysis, and complex network analysis. However, as a combinatorial optimization problem, redistricting optimization remains one of the most difficult research challenges. There are currently few automated redistricting methods that have the optimization capability …

Open / Close: Assimilating Immersive Spaces In Visual Communication, Anika Sarin

Theses and Dissertations

I am interested in two spaces obverse to each other: open and closed. An open space develops organically based on how people inhabit it. Interacting with an open space is a dynamic, sporadic, multisensory, immersive, and subjective experience. In such spaces, we are confronted with an alternative aesthetic, one that is in conflict with the seamlessness of a closed space. A closed space is anchored on definite variables like structure, use and boundaries. While interaction between people and space is important, the space is tightly controlled and interaction is designed. Through this thesis project, I present a method that metaphorically …

Evaluating Lithology As An Erosional Control On A Fluviokarst System In Northeastern Kentucky, Andrew K. Francis

Theses and Dissertations

Longitudinal stream profiles can be used to evaluate landscape evolution. Lithology as a control on a stream profile is especially of interests because fluviokarst systems are characterized by the contact of carbonate and non-carbonate rocks at the surface. Due to the difference in weathering processes between carbonates and non-carbonate rocks, it is likely that there is a difference in their rates of erosion. Cave Branch and its tributary Horn Hollow, are fluviokarst systems located in northeastern Kentucky. This area is primarily comprised of sandstone and limestone. The objectives of this study were to determine if variation in lithology was creating …

Lebanon's Shouf Biosphere Reserve: A Protected Area And Sport Hunting, Robert Watkins Bowdoin Greeley

Theses and Dissertations

Fortress conservation, the act of setting aside for conservation goals and protecting them through sanction, coercion, and violence, towards local users has became the paradigmatic understanding of how protected areas are created and maintained. The fortress conservation critique is marked by a preoccupation with the negative livelihood impacts of these areas, portrays animosity and social conflict between local users and the protected areas, is primarily concerned with national parks and clearly defined protected areas, and places state power at the center of the creation and maintenance of protected areas. This dissertation takes the tenants of fortress conservation to task by …

Synoptic Climatology Of Extreme Snow And Avalanche Events In Southern Alaska, Kristy C. Carter

Theses and Dissertations

Snowfall distribution in southern Alaska during large snowfall events (>12 inches/day) is complex and dependent on several small-scale factors. Output from highresolution WRF simulations was used to provide further insight into factors that contribute to differences in precipitation patterns. Common synoptic patterns among large snowfall events and cities were studied to create a snow climatology for seven cities in southern Alaska based on the predominant wind flow at the surface and aloft and the location of the surface low and 500 mb height field. Results aid in understanding the synoptic set-up for large snowfall events in each city and …

Geospatial Modeling And Assessment Of The Environmentally Sensitive Lands In The Midwestern U.S., William M. Soohoo

Theses and Dissertations

Agricultural land-use change, especially corn expansion, has been accelerating since the 2000s to meet the growing bioenergy demand in the United States. This study identifies the environmentally sensitive lands (ESLs) in the U.S. Midwest and explores the environmental implications of land-use changes in this vital agricultural region. A new distance factor is introduced to a soil erodibility model to take wetlands and waterbodies into account. With a GIS-Ranking Model, the ESLs in 2008 and 2011 (two representative years of corn expansion) in the study region are ranked based on their soil erosion severity. Under various scenarios of bioenergy land-use change …

Hydrologic Modeling Scenarios In A South Carolina Piedmont Drainage Basin, Parker Douglas Leslie

Theses and Dissertations

Changing land cover can drastically alter the hydrologic processes of a drainage basin. At the same time, the hydrologic processes that occur are governed by weather and climate of the region. The Southeastern United States, and more specifically the Piedmont region of South Carolina, is experiencing significant changes to the landscape and highly variable weather and climate conditions. Few modern hydrologic studies that investigate the impact from these dynamic variables on streamflow and the water balance within the region have taken place and further study is warranted because of the drastic change likely to occur. One objective of this thesis …

Barriers To Success: Refugee Mobility In The New South Immigrant Gateway City Of Columbia, Sc, Usa, Alysha V. Baratta

Theses and Dissertations

This thesis explores mobility and service access of refugees who have been resettled in a non-traditional smaller-city immigrant destination of Columbia, South Carolina. I show that delivery of basic refugee social services varies based on support from individual states while federal expectations for refugees to reach economic selfsufficiency are applied equally across the US. I argue that mobility is a major challenge in obtaining these goals, further exacerbated in the context of a smaller resettlement site. Although redistribution to smaller metropolitan areas may provide refugees safer and more affordable housing, less spatial distance to traverse (Mott, 2010), they often lack …

Assessing Individual Transit Vulnerability To Nuisance Flooding In The Charleston, Sc Area, Sumathee Selvaraj

Theses and Dissertations

Minor coastal flooding, also known as nuisance flooding, is projected to be more frequent due to relative sea level rise. Nuisance flood events in Charleston have resulted in various social impacts caused by road closures, traffic disruptions, and economic losses. This thesis presents research conducted to understand the dimensions of individual transit vulnerability to nuisance flooding and how transit vulnerability will be affected by increased extents of nuisance flooding driven by rising sea levels and heavy rainfall. Mixed methods were used to conduct this research in Berkley, Charleston, and Dorchester Counties, South Carolina. An electronic, in-person survey was administered at …

This study also situates Perna’s conceptual work in relation to his field of human geography, in the specific Venezuelan context.

The Innovation Makerspace: Geographies Of Digital Fabrication Innovation In Greater New York City, Kathryn Dickerson

Theses and Dissertations

Desktop digital fabrication technology has the potential to powerfully alter the economics, geography, and sociology of production. The desktop technology cannot reach its potential for widespread impact until it improves in quality and decreases in price. Makerspaces have emerged in the United States in the last eight years as informal social organizations where innovation in this technology may be occurring. This study examines whether innovation in digital fabrication technology has occurred, or has the potential to occur, at makerspaces in the New York City area.
