A Spatiotemporal Characterization of Water Resource Conditions and Demands for the Wilcox Groundwater Basin, Southeastern Arizona

Creator:: Job, Carl
Abstract:: Groundwater overdraft in the Wilcox Groundwater Basin, as a consequence of increasing rates of agricultural groundwater withdrawal, has led to significant regional groundwater level decline and threatens to undermine the basin’s long-term water resource security. Updated characterization of the basin’s water resource conditions and agricultural water demand is critically important...

Assessing Opportunities and Constraints of Monitoring Refugee Settlement Socioeconomic Conditions using Nighttime Lights: A Case Study of Bidi Bidi and Rhino Camp Refugee Settlements in Uganda During the Covid-19 Lockdown

Creator:: Mizell, Hannah
Abstract:: As of 2022, Uganda hosts the third largest refugee population in the world with roughly 1.5 million refugees settled within 13 districts. With some of the most progressive refugee policies in the world, refugees in Uganda live alongside hosts in integrated settlements to support positive, sustainable socioeconomic relationships in both...

Climate-Smart Aquaculture: A Conceptual Framework for Evaluating Air-Breathing Fish for Sustainable Food Systems

Creator:: Ichien, Stephanie T.
Abstract:: The global demand for food is expected to double by 2050, presenting a need that is complicated by the many interrelated of pressures on the world’s natural resources from climate change, growing urban populations, and increasing development. As one of the fastest growing food production sectors, aquaculture is poised to...

The Impact of Freeze-Thaw Cycles to the Physical and Biogeochemical Properties of Alaskan Permafrost Soils

Creator:: Rooney, Erin C.
Abstract:: Arctic warming is exposing thawing permafrost to repeated freeze-thaw, a disruptive process that can alter soil biogeochemistry and physical structure. To investigate the impact of permafrost exposure to freeze-thaw, soil response was tested across three scales: 2.5 cm³ aggregates, a forested hillslope, and two sites at contrasting latitudes. XCT imaging...

Assessing Seismic Rockfall Impacts on Mobility in Transportation Corridors

Creator:: Holtan, Katherine
Abstract:: The climate and geologic conditions of the Pacific Northwest leaves its roads highly susceptible to rockfall hazards. Rockfalls often occur on steep slopes that experience heavy rainfall, groundwater seepage, or strong shaking from earthquakes. The unpredictable nature of these events often creates substantial problems for communities, transportation infrastructure, and the...

Pacific Madrone Leaf Blight Detection with Unmanned Aerial Systems and Machine Learning

Creator:: Barker, Matthew I.
Abstract:: Ground-based assessments of foliar diseases including leaf blight are time-consuming and costly. We investigated the potential for using an unmanned aerial system (UAS) in conjunction with a multispectral sensor to determine whether we could more efficiently and reliably detect and quantify leaf blight in Pacific madrones. Our methods included ground-based...

Are Bird Habitat Associations Consistent Across Space and Time?

Creator:: Rousseau, Josée S.
Abstract:: The concept of the fundamental niche is frequently used in ecology to define the set of environmental conditions needed by a species to survive and reproduce (Hutchinson 1957). In contrast, the realized niche constitutes the locations where a species actually occurred, which is a function of both the environmental (abiotic)...

Fighting and Foliage: Land System Dynamics in the Colombian Andes-Amazon region

Creator:: Murillo-Sandoval, Paulo J.
Abstract:: In the Colombian Amazon there has been a complex interplay of rebel groups’ control over land, drug trafficking, and absence of the Government of Colombia. Here, I use satellite remote sensing, ethnographic research and statistical models to provide insights into causal effect and causal mechanisms of land change and economic...

Mapping Nearshore Bathymetry with Spaceborne Data Fusion and State Space Modeling

Creator:: Forfinski-Sarkozi, Nicholas A.
Abstract:: Despite numerous techniques for measuring and estimating water depth, bathymetry in the nearshore zone is notoriously difficult to map. Dangerous sea states, noisy environmental conditions, and expensive survey operations, particularly in remote areas, contribute to the difficulties of obtaining data along the coast. Global datasets, derived mainly from satellite altimetry...

New Metrics, Modeling Applications, and Observational Strategies for Snowpacks in Remote, Data-Limited, Mountain Environments

Creator:: Crumley, Ryan L.
Abstract:: The topics in this dissertation center on the snow processes that dominate mountain environments in the Western U.S. and Alaska, particularly in locations lacking long-term observational datasets or locales that are difficult to access in-person. Some are currently glacierized or have been glaciated in the recent past. Each of the...
