How Low A Colorado River Flow To Go? Insights From Numerically Stabilizing Lake Powell And Lake Mead During Crisis, David Rosenberg, Anabelle Myers, Motasem Abualqumboz, Erik Porse

Civil and Environmental Engineering Faculty Publications

Colorado River users are now discussing dividing river flow on a percentage basis (Fleck, 2025; Hager, 2025, Winslow, 2025). This is an important step to managing a declining and more volatile supply. In our prior May 2025 post, we shared a strategy we have worked on for several years— division of river flow—as one of 13 reasons why we have hope for consensus on Colorado River management. In this post, we address the question: How extreme low river flow and reservoir storage should we plan for going forward (Figure 1)? We also share our insights from numerically stabilizing and recovering …

Enhancements And Improvements Of The Radiation Probe - Compact Radiation Probe (Crp), Yihsuan Chou, Loren Chang, Yichung Chiu, Tzuwei Hung, Sinyu Tsui

Small Satellite Conference

As space missions venture beyond Earth's magnetic field, spacecraft face elevated risks from solar energetic particles (SEPs) and galactic cosmic rays (GCRs). Taiwan's first lunar payload—the Deep Space Radiation Probe (DSRP)—was developed to measure radiation dose, dose rate, and SEU rates during Earth–Moon transit. However, flight data revealed limitations in SEU detection and system operation. To address these issues and support CubeSat-class missions, the Compact Radiation Probe (CRP) was developed for the upcoming COSPAR-1 mission.

Northern Arizona Ecological Conservation: Assessing Quaking Aspen Health In Northern Arizona Using Earth Observations, Ikram Morso, Luke Collins, Margaret Cox, Melissa Schwan

Small-stand Challenges in the Northern Rockies

Brytten Steed, PhD, USFS Forest Entomologist (retired) Forest Health Protection - Missoula Field Office

Aspen in the Northern Rocky Mountains exist more often as small, scattered patches or “stringers” than the iconic landscapes of aspen found elsewhere. Like early-season fireflies, they dot the landscape where moisture is present, ringing potholes, lining streams, or clinging to topographies rich in subsurface moisture. Their rarity belies their importance to wildlife, livestock, fire movement, and humans. Aspen are preferred browse for large herbivores, a hotspot for birds, and home to a diversity of plants. People, too, gravitate …

Sustainable Master Planned Gateway Communities: The Kamas Valley Case, Zachary Sannar

All Graduate Reports and Creative Projects, Fall 2023 to Present

Gateway communities (towns and cities located near public lands and natural amenities) are experiencing significant and often disruptive change as they transition from economies historically rooted in natural resource extraction to those increasingly driven by tourism and amenity-based migration (Howe et al., 1997; Stoker et al., 2020).

In the Intermountain West, places like Jackson, Wyoming; Springdale, Utah; and West Yellowstone, Montana exemplify this trend, and Kamas Valley is emerging as part of this broader pattern.

Although these communities share a deep cultural and economic connection to their landscapes, they now face mounting pressures from population growth, changing land uses, and …

A Computational Study On Impact Performance Of Concrete Barriers For Protecting Transportation Assets, Ashesh Pokhrel

All Graduate Theses and Dissertations, Fall 2023 to Present

Highway safety is a major concern as roads accommodate increasing numbers of vehicles, including large trucks and tractor-trailers. Concrete barriers are commonly used along highways and bridges to prevent accidents by redirecting vehicles and protecting important structures like bridge piers. However, their effectiveness depends on how well they withstand vehicle impacts, how they perform after being damaged in previous crashes, and how they protect bridge piers when space is limited. This research examines these issues using advanced computer simulations to better understand barrier performance and improve roadway safety.

The first part of this study reviews how researchers and engineers use …

An Optimization Study Of Multi-Orifice Synthetic Jets, Rhett T. Parry

All Graduate Theses and Dissertations, Fall 2023 to Present

From the mixing of creamer into coffee, to the dynamics of a dust storm, or smoke rising from a chimney—everything is driven by turbulent fluid motion. Experimentalists bring the complex driving mechanism that is turbulence into a laboratory setting to fundamentally understand its behavior in response to certain test parameters. Researchers may choose various drivers, or “actuators”, of fluid motion to start the turbulent regime for their applications. However, in building an entire experimental apparatus, they miss the step of ensuring that an individual driver is performing as best as possible. A common actuator used in experimental studies is a …

Risk Perceptions And Water Governance: Experiences Of Irrigation Companies In The Great Salt Lake Basin Of Northern Utah, United States, Bailey M. Holdaway

All Graduate Theses and Dissertations, Fall 2023 to Present

Irrigation companies are important water management entities in the Western US. However, these companies often face barriers when managing water. Particularly as the state of Utah grows and water resources are drying, there is much finger pointing at those in irrigation and agriculture for better water management. However, pointing fingers without the participation of these companies often does not lead to effective water management outcomes. Therefore, it is important to understand the role of these irrigation companies, and particularly how they are approaching water management.

I set out to understand the role of these irrigation companies, specifically in the Great …

Role Of Quartz Grain Size And Saturation On Fault Strength And Frictional Healing, Sapana Regmi

All Graduate Theses and Dissertations, Fall 2023 to Present

Rocks near the Earth's surface (less than 5 kilometers deep) often break and grind against one another to create crushed rock materials known as fault gouge. These fault gouges are filled with fragmented particles and broken rocks, which vary in grain size over time and space due to repeated earthquakes. This variation in grain size distribution along fault gouge can affect the strength of the fault, how it slips during an earthquake and how it 'heals' or recovers strength between earthquakes. Further, fault gouges often contain water from underground sources, which can influence how they slip. Previous studies have examined …

The Effects Of National Elite Signaling On Ranked Choice Voting In Utah, Mathew Woodman

All Graduate Reports and Creative Projects, Fall 2023 to Present

Ranked-Choice Voting (RCV) is a voting method used in few cities in the United States. There has recently been an increase in interest in adoption of the voting method in other cities using pilot programs, much like the one introduced in Utah. Ranked-Choice Voting has become a topic of contention with strong disapproval coming from opponents of the voting system. The questions are why there is disdain for Ranked-Choice Voting, and why such disdain seems to exist more heavily in Republican camps. Public opinion polling from “likely and confirmed Utah voters” in Salt Lake, Utah, and Grand Counties, conducted by …

Examining The Development Of Collective Classroom Efficacy At The Secondary Level, Bradley K. Dutson

All Graduate Theses and Dissertations, Fall 2023 to Present

How can educators develop cohesive and productive learning communities at the secondary level? Prior research has investigated how classrooms develop collective classroom efficacy (CCE) or the shared belief that, as a classroom, they can achieve their learning goals together as a community. Previous studies suggest that CCE at the elementary level is developed with a teacher acting in the role of a community organizer. The teacher employs social and academic practices which incorporate the use of relevance, relationship, and responsibility. These help to establish four key elements of developing CCE which include: 1) a positive classroom environment, (2) persistence and …

Pressure Recovery Analysis Downstream Of Valves And Meters: An Experimental And Numerical Investigation, Stephen J. Sanders

All Graduate Theses and Dissertations, Fall 2023 to Present

In pressurized water systems, flow control devices such as valves and meters cause pressure losses that can affect energy efficiency and measurement accuracy. Industry standards assume that all devices recover within the same distance downstream, but this may not be true for all device types. In this study we used laboratory testing and computer modeling to determine how far downstream pressure stabilizes after flowing through various valves and meters. Devices like Venturi meters recovered pressure quickly, while orifice plates required longer distances and resulted in greater permanent energy loss. In most cases, pressure recovered within four to six pipe diameters. …

"Why Does Coach Do That?" Exploring Influences Of Coach Behavior In Non-Elite Women's Artistic Gymnastics, Katherine Vernay Adams

All Graduate Theses and Dissertations, Fall 2023 to Present

This two study dissertation explores coaching in women's artistic gymnastics, as the sport has been criticized for harsh and controlling coaching methods. The first study investigated whether coaches who experienced mistreatment as young gymnasts were more likely to adopt controlling coaching practices. While there was no direct link, those with a history of mistreatment tended to struggle more with managing their emotions. The second study tested whether coaches view controlling coaching as more acceptable for younger or more advanced gymnasts. The results showed that neither age nor skill level made a difference—controlling coaching was generally viewed as unacceptable, while supportive …

Gender-Diverse Individuals' Mathematics Self-Efficacy, Aliya Halterman

All Graduate Theses and Dissertations, Fall 2023 to Present

Many factors influence how well someone learns and achieve in school and daily living, with motivation being especially important. One key part of motivation is something called self-efficacy, which refers to how much someone believes they can successfully do a specific task (Bandura, 1986; 1997). Research has shown that self-efficacy plays a major role in how well people do, and the quality of their efforts (Pintrich & Schrauben, 1992; Weinstein & Mayer, 1986; Zimmermann, 2000). Additionally, mathematics skills are tied to better outcomes in school, careers, and in daily life. Mathematics also has also had a complex history when it …

Exploring Methods For Quantifying Uncertainty In Neural Network-Based Turbulence Closures, Cody Grogan

All Graduate Theses and Dissertations, Fall 2023 to Present

Machine Learning (ML) is a very promising field for data-driven modeling of different phenomena. In the field of Computational Fluid Dynamics (CFD), ML is an enticing alternative to traditional methods to improve the accuracy and computational efficiency of simulations. However, many ML models, like Neural Networks, don’t quantify their uncertainty or indicate their confidence in a prediction to those who wish to use them. This is especially important because the use of inaccurate ML predictions in a CFD simulation can greatly impact the validity of a simulation. However, with uncertainty quantification, an ML model can indicate to a modeler the …

An Ant-Colony Approach To Scheduling Charging Sessions Of Electric Vehicle Fleets With Heterogeneous Scheduling Constraints, Derek D. Redmond

All Graduate Theses and Dissertations, Fall 2023 to Present

Electric vehicles and electric-vehicle fleets are gaining widespread usage. A major challenge of managing an electric-vehicle fleet is scheduling when the vehicles can charge and when the vehicles can complete their tasks. Finding smart ways to schedule electric-vehicle charging reduces both the cost of charging vehicles and increases the health of the grid and the environment. This best-of-both-worlds outcome is because of the pricing structure that electric utility companies use. When minimizing the cost of charging the vehicles, it is important to consider that vehicle fleets have constraints on when they can charge. Vehicles are usually limited by the tasks …
