Development Of A Multiband Remote Sensing System For Determination Of Unsaturated Soil Properties, Cyrus D. Garner
Graduate Theses and Dissertations
A multiband system including active microwave sensing and visible-near infrared reflectance spectroscopy was developed to measure unsaturated soil properties in both field and laboratory environments. Remote measurements of soil volumetric water content (θv), soil water matric potential (ψ), and soil index properties (liquid limit [LL], plastic limit [PL], and clay fraction [CF]) were conducted. Field-based measurement of θv was conducted using a ground-based radar system and field measurements within 10 percentage points of measurements acquired with traditional sampling techniques were obtained. Laboratory-based, visible and near infrared spectroscopy was found to be capable of obtaining empirical, soil specific regression functions (partial …

The Spatial Ordering Of Nabataea: An Integrated Analysis Of The Geography, Architecture, And Morphology Of Nabataean Petra, Christopher Clifton Angel
Graduate Theses and Dissertations
The Nabataean city of Petra is well known for its sandstone architecture and rock-hewn funerary landscape. Over the last few decades, numerous studies examined their history, culture, art, and architecture. The few studies that assessed the urban space of Petra focused on the functional properties of individual architectural forms and their nominal placement within the overall landscape. This study focused on the spatial configurations of architecture as relational to the dynamics of Nabataean politics and ritual where shifts in social order manifested similar shifts in spatial order which in turn produced and reproduced forms of social order. The production of …

Spatial Variability Of Seedling Disease Pressure In Cotton Fields, Kyle Douglas Wilson
Graduate Theses and Dissertations
Seedling diseases are important factors in cotton stand establishment, and seedling disease pathogens are widespread in fields in Arkansas. Little is known about the variability of seedling disease pressure within fields. With expanded adoption of site-specific management and other precision agriculture approaches, cotton producers are increasingly interested in predicting seedling disease pressure, particularly in spatially variable fields. The cotton seedling disease pathogens include the soilborne pathogens Thielaviopsis basicola, Rhizoctonia solani, Pythium spp., and Fusarium spp. These pathogens can survive in soil for long periods and, and when the environment is conducive, these pathogens can act individually or in combination to …
Assessing Landslide Susceptibility With Gis Using Qualitative And Quantitative Methods In Knox County, Nebraska,

University of Nebraska-Lincoln
Assessing Landslide Susceptibility With Gis Using Qualitative And Quantitative Methods In Knox County, Nebraska, Christian J. Cruz
Department of Geography: Dissertations, Theses, and Student Research
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 …

Stratospheric aerosols (SAs) are a variable component of the Earth's albedo that may be intentionally enhanced in the future to offset greenhouse gases (geoengineering). The role of tropospheric-sourced sulfur dioxide (SO2) in maintaining background SAs has been debated for decades without in situ measurements of SO2 at the tropical tropopause to inform this issue. Here we clarify the role of SO2 in maintaining SAs by using new in situ SO2 measurements to evaluate climate models and satellite retrievals. We then use the observed tropical tropopause SO2 mixing ratios to estimate the global flux of …

Sacral Variability In Tailless Species: Homo Sapiens And Ochotona Princeps, Robert G. Tague
Faculty Publications
Homo sapiens is variable in number of sacral vertebrae, and this variability can lead to obstetrical complication. This study uses the comparative method to test the hypothesis that sacral variability in H. sapiens is associated with absence of a tail. Three species of lagomorphs are studied: Ochotona princeps (N = 271), which is tailless, and Lepus californicus (N = 212) and Sylvilagus audubonii (N = 206), which have tails. Results show that O. princeps has (1) higher diversity index for number of sacral vertebrae (0.49) compared to L. californicus (0.25) and S. audubonii (0.26) and (2) significantly higher percentage of …

Impact Of High-Resolution Topographic Mapping On Beach Morphological Analyses Based On Terrestrial Lidar And Object-Oriented Beach Evolution, Xuelian Meng, Xukai Zhang, Rodolfo Silva, Chunyan Li, Lei Wang
Faculty Publications
This research applied terrestrial LiDAR for laboratory beach evolution experiments to quantify the impact of resolution on topographic mapping and change analyses. The multi-site registration and multi-Temporal scanning processes produced high accuracy (-0.002 - 0.003 m) topographic models in a wave tank environment. Morphological analyses based on surface change and profiles showed that models of all resolutions were capable of capturing major sediment changes in relatively smooth areas. However, higher resolution models were necessary in areas with rough surfaces and sudden elevation changes, while coarser resolution models smoothed the roughness and underestimated feature height (e.g., peaks and troughs). Decreasing resolutions …

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 …

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 …

Governing The Urban Water Commons : Essays On Collaborative Policy Networks In A Polycentric Ecology Of Urban Water Policy Games., Emmanuel Frimpong Boamah
Electronic Theses and Dissertations
Governing social-ecological systems, such as the urban water commons, is a multi-scale and multi-sector (polycentric) human-environment process. This dissertation interrogates this process by situating itself within the Ecology of Games Framework by Norton Long (and updated by Mark Lubell) and the literature on polycentric governance by the Bloomington School of Political Economy. The dissertation’s three essays 1) offer both theoretical and methodological means to enact polycentric public economies within the ecology of games framework, and 2) explicate the conditions under which interoganizational collaboration is fostered within a polycentric ecology of policy games in governing the Middle Rio Grande urban watershed. …
Remote Sensing Insights Into Storage Capacities Among Plains Village Horticulturalists,

Remote Sensing Insights Into Storage Capacities Among Plains Village Horticulturalists, Adam Wiewel
Graduate Theses and Dissertations
Maize was a fundamental component of the diet and economy of Middle Missouri Plains Village groups, sedentary farmers with settlements along the Missouri River during the last millennia. More than a century of study has contributed to our understanding of agricultural production among these peoples, but little effort has been made to consider temporal variation in production. Such an understanding is crucial to examining changes that occurred before and after the arrival of colonists and their trade goods in the seventeenth century. Plains archaeologists have suggested that the storage capacity of Middle Missouri villages increased during the sixteenth through the …

Oil, Space, And National Imaginaries : Discursive Productions By Standard Oil New Jersey Post Wwii., Michael Poindexter
Electronic Theses and Dissertations
In a moment of self-representation, Standard Oil New Jersey commissioned a large photo ‘documentary’ project of nearly 80,000 images taken between the years 1943 to 1950. Produced for publication and exhibition, images captured “how oil seeped into every joint” of America, and displayed a specific landscape for post WWII economies. While a stable and centralized industry was ever more tied to the state’s idea of national security, Standard Oil needed a public relations project to address social concerns of big oil. This singular perspective on oil space is problematic. Community histories and social relations are seen through Standard Oil’s own …

“A Theoretical Model For Critical Geographies Of Gentrification: A Comparative Analysis Of Globalization In Two Gay Villages”, Spencer Nelson
Geography Honors Projects
Abstract: The role of gay villages in gentrification has long been contemplated yet their relationship to the global circulation of capital is understudied. This thesis sheds light on this phenomenon through an urban political ecology of gentrification and provides a new model of critical geographies of gentrification. The model is illustrated through ethnographic research in the two gay villages of De Waterkant in Cape Town, South Africa, and Loring Park in Minneapolis, Minnesota. The relationship between gentrification and globalization is analyzed through the four lenses that bring flows of financial capital, culture, technology, and ideology into focus and offers a …

Sensors Everywhere: Using Satellites And Mobile Phones To Reduce Information Uncertainty In Human Rights Crisis Research, Christoph Koettl
Genocide Studies and Prevention: An International Journal
This article critically reviews the use of ICTs for human rights crisis research. While focusing on two specific technologies—satellite imagery and mobile phone technology—it proposes a general framework for analyzing the added value of ICTs. The author suggests that their added value in mass atrocities research arises from their ability to reduce information uncertainty, a challenge that is exacerbated in the digital age. This is different from delivering “truth”, an inaccurate description that only leads to unfulfilled expectations and hopes. The article is written from a practitioner’s perspective, drawing from the work of a global human rights watchdog, thus avoiding …

Electronic Theses and Dissertations
The well-known symbol for conservation, the giant panda bear, and the original red panda have been forced into remote habitats due to anthropogenic disturbance, making ecological study difficult. Therefore the first known species distribution model was created to predict the most likely areas of occurrence within the known range of these elusive animals. These models were then projected onto North America and evaluated against existing breeding programs. Additionally, the close proximity of the Gray Fossil Site and the discovery of the most complete fossil red panda specimens in the world allowed ecomorphological comparisons between the modern red panda, Ailurus fulgens …
