Repairing The Relationship Between Trains And Traffic In Columbia, South Carolina, 2017 University of South Carolina
Repairing The Relationship Between Trains And Traffic In Columbia, South Carolina, Andrea Esselman
My intention with this paper is to inform readers of the history and complexity of the issues with the trains and other traffic in Columbia, South Carolina. While it may not offer specific solutions to the problems, it does examine solutions that have been proposed and reasons why these solutions have not been pursued. The reader should take away a deeper understanding of why things are in their current state in relation to the trains and the automobile traffic in Columbia. Ultimately this information can keep the public informed so that better decisions can be made in the future.
Environmental Justice And Gis: A Comparison Of Three Gis Methods For Estimating Vulnerable Population Exposed To Brownfield Pollution In Portland, Oregon, Kyle Goodman
Geography Masters Research Papers
This project compares three GIS techniques that estimate populations who are potentially affected by environmental contamination in Portland, Oregon. All three GIS techniques utilize polygon containment to estimate populations potentially exposed to pollutants based on block level census data. In this study, multiple buffer distances at half-mile increments were used across all three techniques. Circular Euclidean distance buffers surrounding a known contaminated property, such as documented brownfields, approximate the contamination zone. Accurate estimates for populations exposed to harmful environmental conditions could provide a better understanding of environmental justice issues. The specific research questions were: 1) Are the population estimates sensitive ...
Stream Sedimentation Patterns In An Urban Beaver System: Fanno Creek, Oregon, 2017 Portland State University
Stream Sedimentation Patterns In An Urban Beaver System: Fanno Creek, Oregon, Alexandra Joan Santora
Geography Masters Research Papers
Beaver activities can cause drastic changes to hydrogeomorphic processes by impounding waterways through the construction of dams, trapping sediments and reducing the downstream sediment load. The presence of beaver is increasing in urban areas. Urban streams exhibit hydrogeomorphic processes distinct from natural systems because of changes in land cover that alter hydrology. This case study was developed as part of an effort to understand the sedimentation patterns of a beaver impounded urban stream in Beaverton, Oregon. Twelve sediment samples were collected and processed for organic matter content and particle size and sediment depths were calculated using GIS software from data ...
Examination Of The Potential Of Terrestrial Laser Scanning And Structure-From-Motion Photogrammetry For Rapid Nondestructive Field Measurement Of Grass Biomass, Sam D. Cooper, David P. Roy, Crystal B. Schaaf, Ian Paynter
GSCE Faculty Publications
Above ground biomass (AGB) is a parameter commonly used for assessment of grassland systems. Destructive AGB measurements, although accurate, are time consuming and are not easily undertaken on a repeat basis or over large areas. Structure-from-Motion (SfM) photogrammetry and Terrestrial Laser Scanning (TLS) are two technologies that have the potential to yield precise 3D structural measurements of vegetation quite rapidly. Recent advances have led to the successful application of TLS and SfM in woody biomass estimation, but application in natural grassland systems remains largely untested. The potential of these techniques for AGB estimation is examined considering 11 grass plots with ...

This thesis examined what type of relationship existed between snow water equivalence (SWE) volume and groundwater elevation within six sub-watersheds in Utah. Data was gathered on SWE from seventeen SNOTEL sites and groundwater elevation data was gathered from six continuously monitored groundwater wells. This data was gathered for January through May for 2011, 2013, and 2014 in order to represent the water conditions that were above average, below average, and average respectively. Using MLR formulas the total SWE for each sub-watershed was determined for each year/month. Afterwards a correlation analysis was performed to determine if any association existed between ...
Understanding The Vulnerability Of The Population Of Afghanistan Under Multiple Natural And Anthropogenic Risks With An Indicator-Based Analysis, 2017 University of Tennessee, Knoxville
Understanding The Vulnerability Of The Population Of Afghanistan Under Multiple Natural And Anthropogenic Risks With An Indicator-Based Analysis, Matthew Repine Miller
The purpose of this study is to understand the vulnerability to natural and anthropogenic hazards of the population of Afghanistan and the social factors which enhance or moderate such vulnerability. While vulnerability studies are commonly conducted in the United States, as well as many other global north countries, most studies of this type utilize data collected by central government entities in the form of a census which is periodically executed and uses standardized collection methods. In the case of Afghanistan, and many other countries in the global south, such data is hard to acquire, lacks a high level of confidence ...

Effects Of Switchgrass Related Land-Use Changes On Aquatic Macroinvertebrates, Latha Malar Baskaran
This research examines if switchgrass-based land-management practices have the potential to influence aquatic macroinvertebrates through changes in stream flow and water quality. The number of taxa in Ephemeroptera, Plecoptera, and Trichoptera orders (EPT taxa richness/EPT-TR) is analyzed as an aquatic macroinvertebrate bioindicator in the context of regional environmental effects, and changes in stream flow and water quality. This dissertation is structured as three manuscripts that link together to address the overall research question.
The first manuscript focuses on identifying regional environmental variables that influence EPT-TR across ecoregions in Tennessee. The influences of temperature, precipitation, geology, soil, stream flow and ...
Impacts Of Thermal Time On Land Surface Phenology In Urban Areas, 2017 South Dakota State University
Impacts Of Thermal Time On Land Surface Phenology In Urban Areas, Cole Krehbiel, Xiaoyang Zhang, Geoffrey Henebry
GSCE Faculty Publications
Urban areas alter local atmospheric conditions by modifying surface albedo and consequently the surface radiation and energy balances, releasing waste heat from anthropogenic uses, and increasing atmospheric aerosols, all of which combine to increase temperatures in cities, especially overnight, compared with surrounding rural areas, resulting in a phenomenon called the “urban heat island" effect. Recent rapid urbanization of the planet has generated calls for remote sensing research related to the impacts of urban areas and urbanization on the natural environment. Spatially extensive, high spatial resolution data products are needed to capture phenological patterns in regions with heterogeneous land cover and ...
Assessing Landslide Susceptibility With Gis Using Qualitative & Quantitative Methods In Knox County, Nebraska, 2017 University of Nebraska-Lincoln
Assessing Landslide Susceptibility With Gis Using Qualitative & Quantitative Methods In Knox County, Nebraska, Christian J. Cruz
Theses and Dissertations in Geography
This thesis assesses landslide susceptibility using data from LiDAR DEMs, land cover, and soil surveys. Data were assessed quantitatively through Bayesian logistic regression within a geographic information system (GIS) and statistical software to produce a landslide susceptibility map. The study area exhibits moderate relief where bluffs along the Missouri River valley gradually recede into rolling loess-mantled hills further to the south and southeast in Knox County. The six factors used to determine susceptibility to landslides are: land cover, parent material, slope aspect, slope curvature slope degree, and soil series. My findings show an increase in slope is the most significant ...

Mapping Community Space And Place In Mto Wa Mbu, Tanzania Through Surveys And Gis, Jessica Craigg
Georgia College Student Research Events
Cities throughout the African continent have been developing at an unprecedented pace, many of them due to the influence of the tourism industry. This is particularly true in Tanzania, a country famous for its national parks and their draw to tourists who help provide money for development. However, the only way to get the whole story on how to spend this money is through the experiences and needs of the people themselves. This study focuses on a small town in northeastern Tanzania, Mto wa Mbu, situated near Lake Manyara National Park, and its people’s perceptions of the park and ...
Characterizing Large-Scale Meteorological Patterns And Associated Temperature And Precipitation Extremes Over The Northwestern United States Using Self-Organizing Maps, Paul C. Loikith, Benjamin R. Lintner, Alex Sweeney
Geography Faculty Publications and Presentations
The self-organizing maps (SOMs) approach is demonstrated as a way to identify a range of archetypal large-scale meteorological patterns (LSMPs) over the northwestern United States and connect these patterns with local-scale temperature and precipitation extremes. SOMs are used to construct a set of 12 characteristic LSMPs (nodes) based on daily reanalysis circulation fields spanning the range of observed synoptic-scale variability for the summer and winter seasons for the period 1979–2013. Composites of surface variables are constructed for subsets of days assigned to each node to explore relationships between temperature, precipitation, and the node patterns. The SOMs approach also captures ...

Forest Inventory Data, Izaya Numata, Mark Cochrane, Jeppe Kjaersgaard, Sonaira Souza Da Silva
Drought in Amazonia Data Sets
Forest inventory was conducted in Acre, the southwestern Amazon, in July-August in 2014. Field data was collected in four fragmented forest areas. In addition, this forest inventory includes data in forest areas burned in 2005 and 2010 and unburned forest areas. Forest inventory includes information on vegetation species and stem diameter at breast height (DBH) at each plot of 25m x 25m. All trees with DBH ≥ 10cm were measured at 25m x 25m plots and those with DBH< 10cm and lianas were measured at 10m x 10m and 5m x 5m subplots within each 25m x 25m plot.

Half of Earth’s land surface has been altered by human activities, creating various consequences on the climate and weather systems at local to global scales, which in turn affect a myriad of land surface processes and the adaptation behaviors. This study reviews the status and major knowledge gaps in the interactions of land and atmospheric changes and present 11 grand challenge areas for the scientific research and adaptation community in the coming decade. These land-cover and land-use change (LCLUC)-related areas include 1) impacts on weather and climate, 2) carbon and other biogeochemical cycles, 3) biospheric emissions, 4) the ...
Assessing Changes In Land Cover In Southeast Louisiana From 2001 To 2011 Using Time-Series National Land Cover Data, 2017 Western Michigan University
Assessing Changes In Land Cover In Southeast Louisiana From 2001 To 2011 Using Time-Series National Land Cover Data, Ashley Tarver
Each year, Louisiana loses 20 to 25 square miles of land. If land loss persists at the current rate, a forced migration of the human population with serious implications may be warranted. Although studies have measured land use/land cover change in southeast Louisiana over multiple decades, a recent analysis of landscape changes since Hurricane Katrina’s landfall in 2005 is needed to identify areas with chronic long-term wetland losses and associated economic development patterns. This study, therefore, compares land cover and land use changes including wetland loss, and subsequent increases in developed land in ten parishes from 2001 to ...
Exploration Of Scaling Effects On Coarse Resolution Land Surface Phenology, 2017 South Dakota State University
Exploration Of Scaling Effects On Coarse Resolution Land Surface Phenology, Xiaoyang Zhang, Jianmin Wang, Feng Gao, Yan Liu, Crystal Schaaf, Mark Friedl, Yunyue Yu, Senthilnath Jayavelu, Joshua Gray, Lingling Liu, Dong Yan, Geoffrey M. Henebry
GSCE Faculty Publications
Numerous land surface phenology (LSP) datasets have been produced from various coarse resolution satellite data and different detection algorithms from regional to global scales. In contrast to field-observed phenological events that are defined by clearly evident organismal changes with biophysical meaning, current approaches to detecting transitions in LSP only determine the timing of variations in remotely sensed observations of surface greenness. Since activities to bridge LSP and field observations are challenging and limited, our understanding of the biophysical characteristics of LSP transitions is poor. Therefore, we set out to explore the scaling effects on LSP transitions at the nominal start ...
Precipitation Intensity Trend Detection Using Hourly And Daily Observations In Portland, Oregon, 2017 Portland State University
Precipitation Intensity Trend Detection Using Hourly And Daily Observations In Portland, Oregon, Alexis Cooley, Heejun Chang
Geography Faculty Publications and Presentations
The intensity of precipitation is expected to increase in response to climate change, but the regions where this may occur are unclear. The lack of certainty from climate models warrants an examination of trends in observational records. However, the temporal resolution of records may affect the success of trend detection. Daily observations are often used, but may be too coarse to detect changes. Sub-daily records may improve detection, but their value is not yet quantified. Using daily and hourly records from 24 rain gages in Portland, Oregon (OR), trends in precipitation intensity and volume are examined for the period of ...
