Defending A Nation: Synthesizing Geographic Information System Analysis And Ground Penetrating Radar To Locate Battlefield Features Associated With The 1780 Siege Of Charleston, Lisa Gardiner
All Theses
Common methods used to locate battlefield features have not been utilized extensively on the Charleston peninsula. This thesis explores methods used to locate battlefield features and their effectiveness on the Charleston peninsula. The methods were utilized in areas related to the Siege of Charleston in 1780 during the American Revolution. These methods include research into historic accounts of battlefield features, geographic information systems (GIS) to georeference historic maps of the Charleston peninsula, LiDAR to detect the topography of the land and locate any changes to the land over time, and finally ground penetrating radar (GPR) to locate any battlefield features. …
Comparison Of Saturated Hydraulic Conductivity Using Geospatial Analysis Of Field And Ssurgo Data For Septic Tank Suitability Assessment, Joshua Randall Weaver
Comparison Of Saturated Hydraulic Conductivity Using Geospatial Analysis Of Field And Ssurgo Data For Septic Tank Suitability Assessment, Joshua Randall Weaver
All Theses
Saturated hydraulic conductivity (Ksat) is a soil property linked to ecosystem services and it is often used in septic tank suitability determination at various scales. Field and laboratory measurements of Ksat and septic tank suitability are time-consuming and expensive. Soil Survey Geographic Database (SSURGO) data are available for the United States, but limitations of using SSURGO data for Ksat and septic suitability determination are not fully understood. The objectives of this study were to quantify and compare depth to limiting layer, thickness of limiting layer, and Ksat values for a 147-hectare Cornell University Willsboro Research Farm, located in upstate New …
Comparing Ssurgo Data Versus Geospatial Field Measurements To Estimate Soil Texture And Infiltration Rate Classes In Glaciated Soils, Stephen Austin Cole
Comparing Ssurgo Data Versus Geospatial Field Measurements To Estimate Soil Texture And Infiltration Rate Classes In Glaciated Soils, Stephen Austin Cole
All Theses
The infiltration rate (IR) of water is a key soil property related to hydrological processes, soil health and ecosystem services. However, detailed measurements of IR in the field and/or laboratory are labor-intensive and expensive to perform. Soil judging in the field provides a rapid and inexpensive method to estimate IR classes based on soil texture, soil organic carbon/matter and soil structure. The objectives of this study were to classify and compare soil texture and IR for the A horizon across the 147-ha Cornell University Willsboro Research Farm using the Soil Survey Geographic (SSURGO) database and field-based measurements. Soil texture was …
Storm Water Damage Risk Assessment Along The South Carolina Heritage Trail, Charles Pellett
Storm Water Damage Risk Assessment Along The South Carolina Heritage Trail, Charles Pellett
All Theses
This study was conducted to better predict and assess damage to high-value small-spatial scale landscapes from storm water. Storm water damage in the form of rill formation across the South Carolina Botanic Gardens (SCBG) Natural Heritage Garden Trail has been modelled as a function of contributing area using D8 and D-infinity flow direction algorithms on a preprocessed LiDAR-derived elevation raster. D8 and D-infinity algorithms were also applied over a set of stochastic Monte Carlo simulations (n=1,000) representing elevation error. The contributing area was calculated using each of the four methods for each 5'x5' cell along the trail. The output was …
Rapid Riparian Buffer Width And Quality Analysis Using Lidar In South Carolina, Emre Akturk
Rapid Riparian Buffer Width And Quality Analysis Using Lidar In South Carolina, Emre Akturk
All Theses
The importance of protecting water quality and aquatic resources are increasing because of harmful human impacts within and around waterways. Establishing or restoring functional riparian areas protect water quality and are a good mechanism to conserve aquatic systems, plants, and wildlife. Laser-based remote sensing technology offers a high resolution approach to both characterize and document changes in riparian buffer zones (RBZs). The objectives of this study were to build a model to calculate riparian buffer width on both sides of a stream using a LiDAR-derived slope variable, to classify riparian buffers and determine their quality, and to evaluate the appropriateness …
Historical Integration Of Remote Sensing Data: Can Gis Extract Information From Grayscale Aerial Photographs?, Kristina Robertson
Historical Integration Of Remote Sensing Data: Can Gis Extract Information From Grayscale Aerial Photographs?, Kristina Robertson
All Theses
There have been many changes in land management policies of the National Forest system over the past 100 years. Changes in policy related to law, population growth and economics directly cause changes in land cover. Global land cover changes are occurring at such a pace and magnitude that they are affecting Earth system functioning (Lambin et al., 2001). The analysis of land cover changes plays a key role in understanding several environmental phenomena, resulting in a need for objective and comparable land cover maps (Gennaretti et al., 2011). Advances in remote sensing and Geographic Information Systems (GIS) have modernized land-use …
Gis And Web Technologies For Assessing Sediment Pollution From Abandoned Developments, Joshua Werts
Gis And Web Technologies For Assessing Sediment Pollution From Abandoned Developments, Joshua Werts
All Theses
The economic crisis that occurred at the time of this research left numerous residential developments in the Southeastern United States in various stages of construction, creating a potential source of sediment runoff to waterways. Sediment runoff is potentially damaging to aquatic ecosystems and lakes. The objectives of this research include identifying these developments in upstate South Carolina through GIS/remote sensing analysis and implementation of an integrated webGIS framework. Residential development locations with significant bare soil areas were identified through GIS analysis involving Landsat 5 TM classification and aerial photograph verification. The Revised Universal Soil Loss Equation (RUSLE) was used in …
