Coming Together And Falling Apart: Producing And Contesting Place On The Atlanta Beltline, Jessica Martinez Jul 2019

Coming Together And Falling Apart: Producing And Contesting Place On The Atlanta Beltline, Jessica Martinez

Theses and Dissertations

In their efforts to revitalize and reimagine Atlanta, local government, private-public entities, and environmental organizations infuse green projects with the rhetoric of community engagement and local participation. The Atlanta Beltline, a circular greenway system of interconnected parks and trails that adaptably reuses abandoned rail lines surrounding the city, is Atlanta’s latest multi-scaled and controversial sustainability project. One of the Beltline’s primary goals is to act as a transformative force to create an equitable and unified city, which is evident in the Beltline’s promotional slogan, Where Atlanta Comes Together. Narratives of community engagement and decisions involved in constructing the Beltline’s built …


Potassium Fertilization Effects On Yield For Wheat, Soybean, And Corn Grown In Coastal Plain Soils, Renada Davis Jul 2019

Potassium Fertilization Effects On Yield For Wheat, Soybean, And Corn Grown In Coastal Plain Soils, Renada Davis

Theses and Dissertations

A study conducted on wheat, soybean, and corn crops was designed to assess the effect of potassium fertilization based on current potassium (K) fertilizer recommendations on crop yield, soil K levels, and plant tissue K concentration. The objectives of this study were to 1) evaluate the effect K fertilization has on crop yield; 2) To assess soil K levels through the duration of the experiment and the effect fertilization may have on soil K levels; and 3) to evaluate the effect of fertilization on plant tissue K concentrations. There was no statistical difference in yields between plots treated with the …


Impacts Of Drainage Systems On Stormwater Hydrology: Rocky Branch Watershed, Columbia, South Carolina, Logan Ress Jan 2018

Impacts Of Drainage Systems On Stormwater Hydrology: Rocky Branch Watershed, Columbia, South Carolina, Logan Ress

Theses and Dissertations

The effects of urbanization and associated land use changes, specifically increases in impervious surfaces, have long been the focal point of urban hydrologic research. However, studies and calculations that consider impervious surfaces alone do not encompass all factors that influence urban hydrologic response. Artificial structures such as storm sewer (SS) systems and road networks increase rates of stormwater conveyance, yet these artificial networks are rarely considered in computations of drainage densities and associated hydrologic alterations. This study examines several hydrologically relevant descriptors that can be used to better understand the impact of urbanization on small watersheds. Rainfall and stormflow data …


Effectiveness Of Conventional And Lid Stormwater Management Approaches With Swmm Modeling: Rocky Branch Watershed, Columbia, Sc, John M. Williams Jan 2018

Effectiveness Of Conventional And Lid Stormwater Management Approaches With Swmm Modeling: Rocky Branch Watershed, Columbia, Sc, John M. Williams

Theses and Dissertations

Increases in percent impervious area and storm-sewer densities in an urbanized watershed lead to increased flood risk in urban areas. Conventional flood-risk management strategies such as detention ponds and low impact development (LID) can reduce peak flows. Research is needed to resolve questions about which strategy is best-suited for stormwater management under various schemes of sizing, distribution, and cost. Conventional and LID strategies differ in associated costs and benefits in addition to effectiveness and location feasibility. Previous research suggests that conventional strategies require less initial investment for design and construction, though LID is more cost effective in the long-term due …


Classifying The Woody Vegetation Community Of Wade Ponds In Colleton County, South Carolina, Wade Biltoft Jan 2018

Classifying The Woody Vegetation Community Of Wade Ponds In Colleton County, South Carolina, Wade Biltoft

Theses and Dissertations

Wetland habitats are some of the most biodiverse ecosystems in the world, varying in both physical and biological characteristics. Geographically isolated wetlands are particularly important to the landscape due to their role in the hydrological cycle and as local centers for biodiversity. In parts of the coastal plain of South Carolina, there are geographically isolated wetlands found in concentrated groups with distinctive size, shape, and distribution. Despite their unique appearance and distribution, these wetlands have been scarcely researched or investigated. This project seeks to explore the plant communities that are contained within these ponds in order to understand their composition …


North American Butterfly Association Counts At Congaree National Park: A Case Study For Connecting Citizen Science To Management, Austin Clarridge Jun 2016

North American Butterfly Association Counts At Congaree National Park: A Case Study For Connecting Citizen Science To Management, Austin Clarridge

Theses and Dissertations

Citizen science is becoming an ever more popular way for scientists and resource managers to deal with needs for large temporal and spatial scale datasets. It provides a free or low cost means for collection of extensive amounts of data across time and space while acting as a public education and outreach tool, empowering communities to be involved in the management decisions being made in their back yard. Though large, well-known citizen science programs such as the Christmas Bird Counts are being used extensively for peer reviewed literature and management decisions, there are numerous smaller, local counts that have the …


A Comparison Of Framing In Two Environmental Conflicts, Alexander M. Iannone Jun 2016

A Comparison Of Framing In Two Environmental Conflicts, Alexander M. Iannone

Theses and Dissertations

Frames can be perspectives about people, objects, events, or settings that guide action based on past experiences and values. Conflicts are created by different stakeholders “holding conflicting frames.” Researchers in the past have used framing analysis to try and better understand environmental conflicts that tend to perpetuate for extended periods of time. A set of researchers have relied on specific framing categories and typologies as a framework for analysis. They have found that the strong presence or lack thereof certain frames can tell us a lot about conflict dynamics and shed light into the undercurrents driving the complexity of the …


A Botanical Survey Of Native And Non-Native Species Along The Three Rivers Greenway In Columbia, South Carolina, Rebecca L. Givens Jan 2015

A Botanical Survey Of Native And Non-Native Species Along The Three Rivers Greenway In Columbia, South Carolina, Rebecca L. Givens

Theses and Dissertations

Baseline surveys are important tools in establishing the present flora located within an area for future monitoring. In addition, knowledge of invasive species presence is essential to help maintain native ecosystem biodiversity. This study aimed to establish a baseline inventory of plant species found along a portion of the Three Rivers Greenway in Columbia, South Carolina, and to create a comprehensive list of native and invasive plant species within this area. In addition, a geographic information system (GIS) was employed to show the spread of a particular known invasive plant species, Hedera helix within the area. Specimens were collected in …


Analysis Of Hurricane Preparedness Levels And Evacuation Intent For South Carolina Coastal Residents, Wesley Chad Seigler Dec 2014

Analysis Of Hurricane Preparedness Levels And Evacuation Intent For South Carolina Coastal Residents, Wesley Chad Seigler

Theses and Dissertations

Many communities across the nation, especially those in coastal areas, are experiencing extensive growth and expansion. This growth and the associated need for additional infrastructure, goods and services, and basic human needs often place people and the things they value in harm’s way due to the threat of a natural disaster. In order to properly prepare and mitigate disaster impacts, individuals and communities must view disasters as events that will likely occur at least once during their lifetime rather than simply outside possibilities. Residents of coastal communities must prepare for potential impacts from hurricanes and resulting storm surges and must …
