This thesis research seeks to document more recent changes in the Green Swamp and to evaluate the effects of various human activities on the system. The study period is from 1985 to 2015. For this time period changes in land use and landcover were examined using neural network classifications. Changes in vegetation health were evaluated by examining Normalized Difference Vegetation Index (NDVI) and Green Vegetation Index …


Murray Energy Corporation V. Mccarthy, Sarah M. Danno Feb 2017

Murray Energy Corporation V. Mccarthy, Sarah M. Danno

Public Land & Resources Law Review

Holding that the widespread effects of environmental regulation on the coal industry constituted sufficient importance, the Northern District of West Virginia ordered the Environmental Protection Agency to conduct analysis on employment loss and plant reduction resulting from regulatory effects. In admonishing the EPA’s inaction, the court ruled that the Agency had a non-discretionary duty to evaluate employment and plant reduction. Furthermore, the court held that the EPA’s attempt to put forth general reports in place of required evaluations was an invalid attempt to circumvent its statutory duty.


Impact Of Urbanization On Temperature Variation In Big Cities: Measuring Health Risk While Targeting Vulnerable Population, Maryam E. Karimi Feb 2017

Impact Of Urbanization On Temperature Variation In Big Cities: Measuring Health Risk While Targeting Vulnerable Population, Maryam E. Karimi

Dissertations, Theses, and Capstone Projects

Densely populated cities are experiencing Urban Heat Island (UHI) effects and localized hotspots. Cities, such as New York can form heat islands all year round. This is primarily due to land surface modifications, radiative trapping in urban canyons and lack of cooling through evapotranspiration caused by displaced trees and vegetation. UHI refers to an increase in air and surface temperature in cities compared to surrounding suburban and rural areas. Large scale environmental forcing can cause subdivisions of UHI throughout a city. The combined of environmental forcing effects lead to the formation of hot pockets within the cities at micro-scale. The …

Effects Of Spatially Distributed Stream Power On Check Dam Function In Small Upland Watersheds: A Case Study Of The Upper Laja Watershed, Guanajuato, Mexico, Zachary Andrew Herzfeld

Dissertations and Theses

Watershed restoration comes in a variety of forms depending on which set of problems are sought to be remedied. Severe soil erosion, in the form of gullying and/or headcutting, can be mitigated through constructing check dams in well-selected locations. This practice has been used throughout the upland subwatersheds within the Upper Laja River watershed in Guanajuato, México. The present study employed Wolman pebble counts to systematically assess the effectiveness of 21 check dams located near the city of San Miguel de Allende. Particle size distributions taken directly downstream and upstream of each check dam were differentiated, aggregated and compared--with the …


Inventory And Analysis Of Some Obsidian Artifacts In The James M. Collins Collection, Matthew Boulanger, Alexis Graves Jan 2017

Inventory And Analysis Of Some Obsidian Artifacts In The James M. Collins Collection, Matthew Boulanger, Alexis Graves

Anthropology Research

An inventory and analysis of four lots of Native American artifacts within the James M. Collins Collection curated at Southern Methodist University reveals the research value of archaeological materials with less than perfect provenience information. All that is known about the origins of these artifacts is that they appear to have come from Oregon. Elemental analysis by energy dispersive X-ray fluorescence identifies the most likely geochemical source for all of the obsidian artifacts in these lots. Source profiles identified from the 75 artifacts represent major sources located in southwestern Idaho. Similarly, the morphology of the artifacts is consistent with material …

A supervised classification methodology is presented to classify the fire type of MODerate resolution Imaging Spectroradiometer (MODIS) active fire detections using training data defined by consideration of Brazilian government forest monitoring program annual land cover maps, and using predictor variables concerned with fuel flammability, fuel load, fire behavior, fire seasonality, fire annual frequency, proximity …


Morpho-Sedimentary Characteristics Of Proximal Gravel Braided River Deposits In A Froude-Scaled Physical Model, Peter Ashmore, Tobias Gardner, Pauline Leduc Jan 2017

Morpho-Sedimentary Characteristics Of Proximal Gravel Braided River Deposits In A Froude-Scaled Physical Model, Peter Ashmore, Tobias Gardner, Pauline Leduc

Geography & Environment Publications

A Froude‐scaled physical model of a proximal gravel‐bed braided river was used to connect the river morphological characteristics, and sedimentary processes and forms, to deposit geometry. High resolution continuous three‐dimensional topographic data were acquired from sequential photogrammetric digital elevation models paired with grain‐size surface maps derived from image analysis of textural properties of the surface. From these data, the full three‐dimensional development of the braided river deposit and grain‐size sorting patterns was compiled over an experimental time period of 41 h during which the model river reworked a large portion of the braided channel. The minimum surface of the deposit …


America's National Parks And The Anthropocene: Addressing The Present To Accommodate The Future In Acadia National Park, Sophie A. Swetz Jan 2017

America's National Parks And The Anthropocene: Addressing The Present To Accommodate The Future In Acadia National Park, Sophie A. Swetz

Honors Theses

In 2000, atmospheric chemist, Paul J. Crutzen, and limnologist, Eugene Stoermer, formally proposed the idea of “the Anthropocene,” a new geologic epoch in which humans are the dominant force shaping the Earth. To claim the Anthropocene's existence is to declare that human actions have altered the Earth in such a way that geologic indicators render it a distinct epoch in the stratification of geologic time. This new epoch emerges as a consequence of increased technological development employed to accommodate an anthropocentric human existence. That is, rapid advancements in technology have driven the transformation from a primarily naturally controlled planet to …

Development Of A Variogram Approach To Spatial Outlier Detection Using A Supplemental Digital Elevation Model Dataset, Zane Daniel Helwig Jan 2017

Development Of A Variogram Approach To Spatial Outlier Detection Using A Supplemental Digital Elevation Model Dataset, Zane Daniel Helwig

Masters Theses

"When developing a ground water model, the quality of the dataset should first be evaluated. Spatial outliers can lead to predictions which are not representative of actual conditions. In order to isolate misrepresentative points, a method is presented which examines the experimental variogram of a ground water elevation dataset. To define a threshold variance between pairs of ground water elevation measures, ground elevation values from a digital elevation model (DEM) are used to determine a maximum reasonable variance expected to occur on the experimental variogram. To determine appropriate DEM parameters, a separate study was also done which observed characteristic behavior …


Climate Change Adaptation For Southern California Groundwater Managers: A Case Study Of The Six Basins Aquifer, Frank Lyles Jan 2017

Climate Change Adaptation For Southern California Groundwater Managers: A Case Study Of The Six Basins Aquifer, Frank Lyles

Pomona Senior Theses

Groundwater has been very important to the economic development of Southern California, and will continue to be a crucial resource in the 21st century. However, Climate Change threatens to disrupt many of the physical and economic processes that control the flow of water in and out of aquifers. One groundwater manager, the Six Basins Watermaster in eastern Los Angeles and western San Bernardino Counties, has developed a long-term planning document called the Strategic Plan that mostly fails to address the implications of Climate Change, especially for local water supplies. This thesis presents an in-depth analysis of the Six Basin Watermaster’s …

Rock Glacier Hydrology In The San Juan Mountains, Colorado, Emilio Ian Mateo

Electronic Theses and Dissertations

Rock glaciers are unique geomorphological features located in alpine environments and are found in the San Juan Mountains of Colorado. There has been little research done on rock glaciers compared to their ice glacier counterparts. Most rock glaciers are located on the northern slope aspect in mountainous areas (Janke 2007), however, there are multiple in southwest Colorado with different aspects. This research project asks how slope aspect influences the hydrological processes of streams sourced from rock glaciers in the San Juan Mountains. This project focused on three basins that are adjacent to each other and share a common peak, Gilpin …


Novel Methods For Quantifying Spatio-Temporal Change In Glaciated And Subaqueous Environments, Jordan Mertes Jan 2017

Novel Methods For Quantifying Spatio-Temporal Change In Glaciated And Subaqueous Environments, Jordan Mertes

Dissertations, Master's Theses and Master's Reports

In many scientific fields, it is important to actively develop new approaches to monitoring and quantifying changes within different systems. Often adapting existing tools or applying techniques from alternative fields can greatly improve our ability to monitor spatial and temporal changes. In this dissertation, I present four studies aimed at demonstrating new innovative ways at improving our ability to observe and quantify changes occurring on glaciers, submerged cultural resources (SCRs) and supraglacial lakes by using technology such as Structure from Motion + Multi-view stereo photogrammetry (SfM) and ground penetrating radar (GPR) surveying combined with facies analysis.

Ironstone Gravel Types In Western Australia: Re-Purposing A Geological Survey To Improve Soil Management, Edward A. Griffin, Karen Holmes, Tim Overheu Dec 2016

Ironstone Gravel Types In Western Australia: Re-Purposing A Geological Survey To Improve Soil Management, Edward A. Griffin, Karen Holmes, Tim Overheu

Conference papers and presentations

The deeply laterised landscapes of Western Australia’s wheatbelt contain large amounts of ferruginous concretions or pisoliths, referred to locally as ironstone gravel. Soil surveys over the years have described ironstone gravel presence and abundance, and the state soil classification system recognises their importance in agriculture by designating ‘ironstone gravel soils’ at the highest level of the classification hierarchy. These gravels have generally been assumed inert in agricultural soils; however, farm trials and anecdotal experience suggest they may play a more active role in nutrient and water retention than previously recognised. Gravelly soil performance under dryland agriculture varies dramatically across the …


Soundscape Mapping: Spatial Variability Of Sound At Furman University, Alec Schindler Dec 2016

Soundscape Mapping: Spatial Variability Of Sound At Furman University, Alec Schindler

Earth and Environmental Sciences Presentations

Looking at the entire soundscape and studying its spatial variability can often give us important information about the health of the ecosystem. However, most previous studies only measure sound intensity, and are therefore limited in their depiction of the soundscape. Another tool for mapping soundscapes is SPreAD-GIS. This tool models sound propagation in an area. However, previous studies have only used it to evaluate the effects of noise pollution, but not applied it towards depicting the soundscape as a whole. I mapped the soundscape of Furman University’s campus using sound intensity as well as many different soundscape indices in order …

Mapping The Impact Of Intensive Rotational Grazing On Soil Fertility Over Time On Greenbrier Farms In Pickens County, South Carolina, Emily Kirby

Earth and Environmental Sciences Presentations

Intensive rotational grazing (IRG) is a management technique that involves a more intentional management approach which includes increased paddock numbers, shorter grazing periods, larger livestock presence per acre, and longer periods of rest on pastures. Potential advantages of this management technique include improved forage quality, greater yield, decreased erosion, stable production during adverse growing condition, and improved soil fertility. This study collects and analyzes data to understand the impact of rotational grazing on soil fertility as measured by SOC (soil organic carbon) and SON (soil organic nitrogen) on Greenbrier Farms in Easley, South Carolina. This study analyzes the transition from …


Habitat Quality Modeling For Bird Species At Furman University, Emma Cook Dec 2016

Habitat Quality Modeling For Bird Species At Furman University, Emma Cook

Earth and Environmental Sciences Presentations

In rapidly urbanizing areas, such as Greenville County in Upstate South Carolina, it is important to study habitat use and quality across land cover types in order to maximize conservation. Habitat fragmentation is a threat to many species of birds in areas with increasing development, especially those species that utilize larger forest patches for nesting and foraging. While land cover type and patch size are extremely important factors in determining habitat quality for birds, recent research has shown that the matrix of surrounding landscape proves to be very important as well. The landscape matrix, sometimes called landscape mosaic, considers the …


Evaluating Lithology As An Erosional Control On A Fluviokarst System In Northeastern Kentucky, Andrew K. Francis Dec 2016

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 …

A Gis Analysis Of Waulsortian-Like Mounds In The Mississippian Of Kentucky And Tennessee, Philip Roberson Nov 2016

A Gis Analysis Of Waulsortian-Like Mounds In The Mississippian Of Kentucky And Tennessee, Philip Roberson

Scholars Week

Following a mass extinction nearly 365 million years ago, bryozoans and crinoids replaced corals and stromatoporoids as the dominant framework organisms in reefs and, during the very earliest part of the Carboniferous period, they built reef-like structures that are known from Europe, North America and Africa. They are characterized by large size, a matrix of carbonate mud, and their major framework organisms.

Waulsortian-like mounds occur in geographically isolated patches in outcrop and in the subsurface of central Tennessee and Kentucky where they are associated with hydrocarbon production. These mounds have the same characteristic organisms as the European mounds and do …
