Caribou Migration And Non-Local Hunting In Northwest Alaska: A Gis Analysis Of Hunting Activity And Its Relationship With Caribou Migration Corridors, Brittney L. Jiménezszabo

Geography and the Environment: Graduate Student Capstones

Indigenous Alaskans rely on subsistence hunting for food, with Barren-ground caribou making up approximately 27% of their diet. It is believed by subsistence hunters that non-local hunting is forcing a change in caribou migration behavior. This study examined non-local harvesting records from 2013 – 2025 in the northwest and interior Game Management Units (GMU) and Alaksa’s Western Arctic Caribou Herd (WACH) migration range data to answer the question, is there a spatial relationship between non-local harvests and WACH migration behavior. Mixed methods included spatial autocorrelation and local statistics. Findings led to the rejection of the null hypothesis which will help …

From Disaster To Resilience: Developing Smart Settlements In The Himalayas, Keshav Bhattarai, Ambika P. Adhikari

Himalayan Research Papers Archive

Nepal’s catastrophic 26 August 2026 Bhote Koshi–Trishuli flood should be understood not only as a humanitarian tragedy but also as a potentially major turning point in updating national settlement and reconstruction policy. Engineers and scientists have described the floods as a glacier–bedrock collapse that triggered an ice-rock avalanche and debris flow. As per the live updates on September 7, 2026, the total death toll was 1,355, and 4,996 people were missing (The Hindu, 2026). Indian and Nepali rescuers worked urgently to locate and rescue people buried under hydropower tunnels, buildings, mud, and landslide debris.

From Himalayan Catastrophe To National Resilience: Lessons From The 2026 Bhote Koshi And Trishuli River Floods In Nepal, Keshav Bhattarai, Ambika P. Adhikari

Himalayan Research Papers Archive

On the morning of 26 August 2026, the mountains above Nepal’s northern frontier delivered a disaster of almost unimaginable speed and scale. A massive mass of ice, rock, and sediment detached in the high Himalayan terrain near the Nepal–Tibet border, descended roughly 1,200 metres, interacted with the Lhende Khola system, and generated a debris-rich flood that surged through the Bhote Koshi and Trishuli river corridors, destroying settlements, markets, roads, bridges, hydropower facilities, and an international border crossing and transforming them into fields of mud, boulders, and wreckage within minutes (ICIMOD, 2026b; Reuters, 2026a). Satellite analysis indicates that a substantial section …

This project assessed vulnerabilities downstream of Utah’s 189 state-regulated, high-hazard dams using a Social-Ecological-Technological Systems (SETS) approach. The purpose of the project was to look beyond engineering and structural risk alone and identify the people, protected ecosystems, critical infrastructure, and land cover types located within mapped dam inundation zones.

Potential inundation zone maps were obtained from the Utah Division of Water Rights Dam Safety Section. They were processed using ArcGIS Pro and integrated with publicly available nationwide geospatial datasets to …

Who Bears The Burden: Tax Incidence And Water Governance In The Middle Rio Grande Conservancy District (Mrgcd) Within Bernalillo County, Michael W. Wilson

Economics ETDs

This study examines how property-value-based assessments within a large western irrigation and flood-control district distribute fiscal burdens across property owners. The empirical analysis is restricted to Bernalillo County within the Middle Rio Grande Conservancy District (MRGCD), using parcel-level administrative data from fiscal year 2025 merged with 2021 irrigation service records and geospatial information. The analysis classifies 34,397 parcels by irrigation status, agricultural valuation enrollment, and primary use to evaluate whether non-irrigating residential and commercial parcels, including renter-occupied properties that lack direct irrigation access, bear a disproportionate share of financial responsibility for a district whose first listed priority under their primary …

Understanding The Long-Run Effect Of Historical Redlining Practices, Yujian Lu

Geography ETDs

Historical redlining practices initiated by Home Owners’ Loan Corporation (HOLC) in the 1930s have produced enduring persistent socioeconomic and environmental disparities in U.S. cities. This dissertation examines their long-term impacts on social vulnerability, urban flood risk, along with public discourse about redlining practices. Results indicate that neighborhoods with HOLC grade A (greenlined) exhibit the lowest overall social vulnerability, while those graded D (redlined) face the highest across U.S. cities. In Chicago, associations between redlining practices and flood risk disparities are stronger than in Los Angeles, reflecting place-specific characteristics among environmental, socioeconomic, and demographic factors shaping flood risk disparities in long …

Measuring And Mapping Spatial Distributions Of Soil Lead Concentrations Along Chicago Parkways: West Ridge And Near South Side, Alyssa M. Kain

DePaul Discoveries

Lead is a heavy metal that can be found in every part of our planet. Human activities like the extraction of fossil fuels and degradation of construction materials can release lead into the environment, where it travels and accumulates in places like our soil or water. Despite efforts to lower the use of lead-based materials within the last fifty years, lead contamination remains as a threat to public health and safety. Elevated blood lead levels are known to cause a variety of health issues particularly for young children and pregnant women. This study aims to measure, map, and analyze the …

DePaul Discoveries

Fine particulate matter (PM₂.₅) poses significant risks to human health and disproportionately affects marginalized communities in urban environments (World Health Organization [WHO], 2021; Tessum et al., 2021). Using low-cost mobile sensors, this study explored spatiotemporal PM₂.₅ concentration patterns along a north–south transect of Halsted Street in Chicago. A 2B Technologies Portable Aerosol Monitor (PAM) mounted on a bicycle was used to continuously record PM₂.₅ concentrations with associated GPS coordinates at approximately two-second intervals during 16 sampling events between 08-12-2025 and 10-05-2025. PM₂.₅ concentrations did not differ significantly among the South Side, West Loop, and North Side regions, contrary to the …

Scraping The Earth: Testing Ndvi As An Indicator Of Military Ground Maneuver Within The Israeli Invasion Of The Gaza Strip, Thomas A. Bergeron

LSU Master's Theses

The advancement of open-source (OSINT) and geospatial intelligence (GEOINT) has allowed independent researchers to study human conflict in new ways, with tools that were previously reserved only for state intelligence agencies. In order to advance methodologies, researchers must continue to evaluate new tools to study war.  Valued for its accessibility and moderate spatial resolution, the Normalized Difference Vegetation Index (NDVI) is one such tool that has not been widely systematically tested for its use in an open-source GEOINT investigation of modern conflict. This study tests NDVI as an indicator of military maneuver by leveraging a mixed-method approach against open-source kinetic …

The Role Of Urban Forests In Mitigating Flooding Effects: A Case Study In Savannah, Georgia, Gillian Bush

Chatham County, a low-elevation region in the Savannah, Georgia metropolitan area along the eastern coast of the United States, is prone to coastal storms and frequently affected by flooding. It serves as a useful case study to better understand the factors behind flooding and the areas that are most at risk. This study uses GIS-based analysis to examine the overlap between flood risk, urban forest cover, and impervious surfaces. The results indicate elevated vulnerability along major transportation corridors and barrier islands, where high-risk flood zones …

Geospatial Governance Failures In The Department Of Defense: Contractor Noncompliance, Ai Adoption, And The Parallel Treatment Of Gis And Cybersecurity, Lyndsey Olmstead

Geography and the Environment: Graduate Student Capstones

The Department of Defense's treatment of geographic information systems and cybersecurity as parallel rather than integrated policy domains produces geographically predictable vulnerability patterns across its global military installation footprint. This capstone investigates that conclusion through original spatial analysis, constructing a five-variable composite geospatial vulnerability index across the six U.S. Combatant Command regions using publicly available unclassified data. EUCOM ranked highest overall, driven by GPS/PNT spoofing density, commercial satellite coverage, and cyber incident frequency; CENTCOM ranked second, driven by OSINT exposure incidents and governance risk. The null hypothesis of random geographic distribution is rejected. Findings confirm the structural governance gap documented …

Not Everyone Gets A Tree: Housing Values, Street Trees, And Equity In Portland, Matthew Moller

University Honors Theses

Street trees are positively associated with Portland home sale prices, but exposure and capitalization are uneven by race/ethnic neighborhood context. Urban trees are ecological assets, but their economic and equity implications remain uneven. This thesis examines street-tree exposure and 2023 residential sale prices in Portland, Oregon (n = 6,414) using a mixed-methodology hedonic design. Ordinary least squares models measure inventoried street-tree counts within 20m, 50m, and 100m buffers together with structural controls and census-block racial and ethnic context. Trees are positively and significantly associated with logged prices at all radii, with scale-sensitive magnitudes and modestly better fit as wider buffers. …

Automation, Migration, And Development: Geography Of Job Precarity In South Asia And North Africa, Keshav Bhattarai, Ambika P. Adhikari

Himalayan Research Papers Archive

This article examines how accelerating automation and the adoption of artificial intelligence (AI) in advanced economies reshape labor markets across the Global South through interconnected channels of production, migration, and remittances. Drawing on the theories and practices of economic geography, labor economics, and development studies, the analysis conceptualizes automation as a transnational shock that contracts demand for migrant labor while simultaneously amplifying employment precarity in labor-surplus economies. The article advances a geographically grounded framework linking technology adoption in core industries with labor displacement, youth unemployment, and urban labor saturation in South Asia and North Africa. It further highlights the macroeconomic …

What’S In A Map?: Evaluating Mapping Techniques And Measures Of Culture To Inform Equitable Cultural Planning In Dallas, Texas, Kena Nicol

Planning Masters Professional Reports

The City of Dallas developed a neighborhood typology map to assess cultural resource distribution as part of its 2018 Cultural Plan, representing a relatively new approach that remains underexplored in academic literature. In the same plan, stakeholders identified equity as a central value, highlighting the need for tools that better support equitable cultural planning. This study evaluates the outcomes of two mapping techniques–cultural asset mapping and opportunity mapping – to examine how each represents cultural resource distribution across Dallas and supports equity-oriented analysis. Cultural asset mapping, the standard approach in cultural planning, identifies the spatial distribution of physical cultural infrastructure. …

Increasing Access To Rural Resources: A Spatial Exploration Of The Social Implications Of Mobility In Appalachian Kentucky., Anna Morris

College of Arts & Sciences Senior Theses

Mobility and accessibility are key predictors in the way that people navigate their communities. However, many rural areas lack holistic transportation systems that support the needs of a diverse range of users. As a result, rural residents, especially rural non-drivers, often face barriers to equitable mobility and access to necessary resources, like healthcare. This study examines the role that mobility plays in facilitating access to healthcare facilities for driving and non-driving populations in Appalachian Kentucky. The study pairs the Enhanced 2-Step Floating Catchment Area method with a demographic index to evaluate mobility equity through spatial accessibility to primary care facilities. …

The Effects Of Impervious Land Cover And Red Tide (Karenia Brevis) On The Florida Manatee (Trichechus Manatus Latirostris) In The Gulf Coast Of Florida, Anna Compton

Honors College Theses

Red tide, caused by the dinoflagellate Karenia brevis, is an algal bloom event that occurs annually in the West Florida Continental Shelf. The algae releases brevetoxin, a toxin that can be fatal to wildlife in high concentrations. These algal bloom events are thought to be exacerbated by warming ocean temperatures and increased nutrient runoff from urbanization. Red tide is responsible for the mass mortality of various marine organisms like the Florida manatee (Trichechus manatus latirostris). This study analyzes the changes in nutrient runoff and sea surface temperatures, and how these factors affected red tide cell concentrations and Florida manatee mortalities …

Creating A Gis-Based Site Suitability Index For A Major Sports Stadium In Kansas City, Theodore E. Blair

Political Science Undergraduate Honors Theses

There are many considerations taken when siting major sports stadiums. Most literature, though, has focused on the political and economic considerations, the negative outcomes of using public money for private projects. However, geographic considerations play a major part in deciding where to site a stadium. These considerations are wide-ranging and can change with the times. This thesis determines ten modern site suitability criteria, and with them, creates a site suitability index using GIS to determine and quantify more and less suitable areas for stadium development. It applies this index to the Kansas City area, as the city is currently in …

Redeveloping Mississippi: A Case Study On Brownfields In Central & Southern Mississippi, Sahrah R. Yeroozedek

Master's Theses

Brownfields, or properties that are or possibly are contaminated with dangerous materials, represent a common obstacle for communities in Mississippi. The real or potential presence of contaminants at these sites often deters investors due to costly cleanup requirements (EPA, n.d. -b). The Environmental Protection Agency (EPA), through its Brownfield Revitalization Program, implemented guidelines for covering the costs and labor associated with the remediation of these properties. The EPA is not, however, responsible for redevelopment that supports long-term environmental and economic sustainability. Although the EPA maintains inventories of all Brownfields, there is also no comprehensive database of Brownfields and their current …

From Guyana To Queens: The Formation Of The Indo-Guyanese Ethnoburb In New York City, 1970-1990, Lianne R. Persaud

Theses and Dissertations

Expanding on Li’s concept of ethnoburbs, this study examines Indo-Guyanese settlement in Little Guyana, Queens (1970–1990). I propose the Vertical Enclave Model, which suggests that multi-family homeownership and internal rental markets facilitated the residential permanence of working-class individuals. The IPUMS Census microdata corroborates this community’s reliance on metropolitan integration, thereby refuting traditional self-sufficient ethnic enclave theories.

The Geography Of Race: A Spatial Analysis Of Free People Of Color In The City Of Charleston (1790-1861), Alexandra Ullman

All Theses

In Charleston, South Carolina, for all but one year from 1790 to 1860, the enslaved and free Black population outnumbered that of the white. Through manumission, the process of an enslaved person gaining their freedom, the free Black population grew substantially and reached a peak in South Carolina during the nineteenth century. This large community of free people of color (FPOC), shifted the social climate by upsetting the balance of white power, thus increasing racial conflict, tension, and legislation that aimed to control the movement of FPOC.

Despite FPOC comprising a significant portion of the total population of Charleston, there …

Machine-Learning Landslide Susceptibility And Runout Modeling In The Nolichucky River Gorge After Hurricane Helene, Grace Braver

Electronic Theses and Dissertations

Extreme rainfall from Hurricane Helene (September 2024) triggered widespread landslides across the southern Appalachian region, highlighting the need for rapid landslide susceptibility assessments that capture both landslide initiation and downstream runout. Traditional susceptibility models often focus solely on initiation zones, limiting their ability to identify which slopes will generate destructive landslides or where material will travel. This study addresses that gap by (1) integrating Geographic Information System (GIS)-based machine learning susceptibility modeling using ArcGIS Pro: Maximum Entropy (MaxEnt) and Random Forest-Based and Boosted Classification and Regression (FBBC) and (2) the U.S. Geological Survey (USGS) Grfin (Growth, Flow, and Inundation) runout …

Increasing Accuracy Of Mapping Local Climatic Zones Using Building Height And Spectral Unmixing, Ian Douglas Stauffer

Masters Theses

Local climatic zone (LCZ) classifications are traditionally done using reflectance, population data, and often climatic data. The goal of this research is to utilize Google’s new “Open Buildings Temporal v1” building data set as well as “spectral unmixing”. With the objective of testing, assessing, and implementing this data set into the workflow of LCZ mapping. After testing the quality of the data against a validated LiDAR data set from the same year as a given “Open Buildings Temporal v1” band, I implemented it into the Random Forest machine learning process. Secondly, I justified the use of spectral unmixing as a …
