The structure, function, and dynamics of Earth's terrestrial ecosystems are profoundly influenced by how often (frequency) and how long (duration) they are inundated with water. A diverse array of natural and human-engineered systems experience temporally variable inundation whereby they fluctuate between inundated and non-inundated states. Variable inundation spans extreme events to predictable sub-daily cycles. Variably inundated ecosystems (VIEs) include hillslopes, non-perennial streams, wetlands, floodplains, temporary ponds, tidal systems, storm-impacted coastal zones, and human-engineered systems. VIEs are diverse in terms of inundation regimes, water chemistry and flow velocity, soil and sediment properties, vegetation, and many other properties. The spatial and temporal …

Investigating Environmental Controls On Temperature Dynamics In An Urban Stream, Matthew Cullen Yates

Dissertations and Theses

Water temperature is a critical environmental variable influencing aquatic ecosystems. This study investigated the factors controlling stream temperature and thermal stratification in Rock Creek (RC) and Bethany Lake, an urbanized watershed featuring an in-line irrigation pond and buried wastewater infrastructure. Previous research suggested that subsurface water flow might drive temperature shifts in Rock Creek during summer periods when flow from Bethany Lake ceases. From 2023 to 2024, continuous temperature and stage monitoring, combined with statistical methods including principal component analysis and random forest regression, were used to evaluate seasonal temperature dynamics and their controlling factors. Results confirmed that seasonal reversals …

What Do Utahns Think About Global Warming And Climate Change?, Scott Hotaling, Kendall Becker, Lendel K. Narine, Jessica Ulrich-Schad, Roslynn Mccann, Peter D. Howe

All Current Publications

In Utah, there is widespread consensus that global warming is happening, and the strength of this consensus has been steadily rising since 2010. Over the last 14 years, some public opinion metrics have risen dramatically while others have been largely stable. The degree of climate impacts in Utah will depend on residents’ perceptions of climate change and support for implementing policies to help the state adapt to warmer temperatures, more extreme weather events, and other associated changes. In this fact sheet, we integrate multiple data sources to summarize the status and trends of Utahns’ opinions on climate change.

Prediction And Control Of Ground Vibrations Due To Blasting Activities In Aggregate Mines, Iddi Ramadhani Bulushi, Geleta Warkisa Deressa, Bhanwar Singh Choudhary

Journal of Sustainable Mining

Predicting and controlling ground vibrations from blasting is crucial for protecting structures and minimizing environmental impacts. This study investigates how explosive quantity and scaled distances affect peak particle velocity and establishes empirical equations to estimate this velocity at different distances from the blast area. The study found that the maximum charge per delay at a peak particle velocity of 10 mm/s was reduced to 13.46% as the delay timing was increased from 0 to 25 ms and 9.99% from 0 to 50 ms delay timing. The reduction of maximum charge with increasing delay timing leads to the reduction of ground …

An Inventory Of Private Well Programs Across The United States, Bethany G. Foust, Ann S. Ojeda, Jessica Curl, Eve Brantley, Stephanie R. Rogers

Journal of Extension

Private well owners comprise approximately 15% of the United States (US) population and are responsible for managing their well water. Management of domestic wells can be burdensome, requires knowledge, and is critical for maintaining clean drinking water. Management resources vary by state and the resource landscape across the US is unclear. Thus, our objective was to inventory where resources exist, while also highlighting geographic areas that may need improved resources to ensure that people have the ability to safely manage their drinking water. Results of this inventory showed that 64% of states have programs; 72% of which were Cooperative Extension.

Restore The Shore: A Guide To Lakeshore Revegetation In The Great Basin, Jes V. Braun, Rae Robinson, Annie L. Henry, Karin M. Kettenring

All Current Publications

Lakeshore vegetation supports many valuable aspects of lake ecosystems: foraging areas for birds, rearing grounds for fish, nutrient cycling, carbon storage, and aesthetic, cultural, and spiritual values. Yet, the vegetation of many lakeshores has been lost or heavily impacted by humans. What can be done to restore lakeshore vegetation to ensure that lakes remain healthy for future generations? In this guide, we summarize best practices for lakeshore revegetation (i.e., the process of actively reintroducing vegetation, usually native species, to a restoration site through seeding and planting) in the Great Basin.

A Machine Learning Model To Predict Wildfire Burn Severity For Pre-Fire Risk Assessments, Utah, Usa, Kipling B. Klimas, Larissa L. Yocom, Brendan P. Murphy, Scott R. David, Patrick Belmont, James A. Lutz, R. Justin Derose, Sara A. Wall

Wildland Resources Student Research

Background

High-severity burned areas can have lasting impacts on vegetation regeneration, carbon dynamics, hydrology, and erosion. While landscape models can predict erosion from burned areas using the differenced normalized burn ratio (dNBR), post-fire erosion modeling has predominantly focused on areas that have recently burned. Here, we developed and validated a predictive burn severity model that produces continuous dNBR predictions for recently unburned forest land in Utah.

Results

Vegetation productivity, elevation, and canopy fuels were the most important predictor variables in the model, highlighting the strong control of fuels and vegetation on burn severity in Utah. Final model out-of-bag R^{2 …}

The Integrated Monitoring Of Karst Systems (Miks) Model, Applied In Karst Studies In Bulgaria, Petar Stefanov, Dilyana Stefanova, Peter Nojarov

International Journal of Speleology

Karst is a widespread natural phenomenon that is highly sensitive and very vulnerable to both natural and various anthropogenic impacts. This is due to the complex structure of karst territories, which comprise both surface forms and complex systems of underground cavities. Therefore, the study of karst requires a geosystem approach and integrated monitoring, which gives a real idea of the state of karst geosystems and the impacts of global changes on karstogenesis. The article presents a model of this approach, which is applied in karst studies in Bulgaria. The methodological basis is the original ProKARSTerra paradigm, based on the geosystem …

Impacts Of Changing Temperatures On The Water Budget In The Great Salt Lake Basin, Grace Affram, Jihad Othman, Reza Morovati, Saddy Pineda Castellanos, Sajad Khoshnoodmotlagh, Diana Dunn, Braedon Dority, Katherine Osorio Diaz, Cody Ratterman, Wei Zhang

Plants, Soils and Climate Student Research

Quantifying the water budget in the Great Salt Lake (GSL) basin is a nontrivial task, especially under a changing climate that contributes to increasing temperatures and a shift towards more rainfall and less snowfall. This study examines the potential impacts of temperature thresholds on the water budget in the GSL, emphasizing the influence on snowmelt, evapotranspiration (ET), and runoff under varying climate warming scenarios. Current hydrological models such as the Variable Infiltration Capacity (VIC) model use a universal temperature threshold to partition snowfall and rainfall across different regions. Previous studies have argued that there is a wide range of thresholds …

Operationalizing And Measuring Climate Change Adaptation Success, Henry A. Bartelet, Michele L. Barnes, Lalu A.A. Bakti, Graeme S. Cumming

Quantitative Methods and Information Technology Faculty Publications

In a context of rapid global change, understanding whether and how adaptation to climate change can be considered successful has become an important research gap within the climate change adaptation literature. Although definitions of adaptation success have been formulated, it remains unclear how they can be operationalized and tested empirically. To address this gap, we operationalized one of the most prominent definitions of successful adaptation within the academic literature, which describes success as adaptations that support reductions in risk and vulnerability without compromising sustainability. Specifically, drawing on data collected from 209 coral reef tourism operators across 28 locations and eight …

Application Of Cementitious Materials And Fiber Reinforcement To Enhance Lime Stabilization For Nebraska Shale Soils, Jongwan Eun, Seunghee Kim, Chung R. Song, Laith Ibdah, Kenaz Owusu

Nebraska Department of Transportation: Research Reports

Lime stabilization is a widely used technique to improve weak subgrades; however, its effectiveness under freeze-thaw cycles remains a critical challenge. This study investigates the incorporation of cementitious materials and fiber to enhance the mechanical properties and environmental resistance of lime-stabilized soils under such conditions. Two types of soil, gray shale (plasticity index of 37.8) and clay soil (plasticity index of 19.0) from Nebraska, were used. Stabilization mixtures included lime dosages of 0%, 3%, and 6% by weight, combined with either 10% fly ash or 3% and 6% cement by weight, and 0% and 1% fiber. The experimental program comprised …

Development Of Soil Survey Methods For Urban Areas, Kohinoor Begum

Dissertations, Theses, and Capstone Projects

Urban soils are the foundation of urban ecosystems and play a vital role in long-term urban sustainability and resiliency. Accurate soil surveys of urban areas should be done at higher resolution since extensive human activities often result in urban soil being highly disturbed and spatially variable. Besides heterogeneity, one of the unique and challenging aspects of urban soil is the nature and properties of its organic carbon with a significant percentage of black carbon (a particulate product of incomplete combustion), which is less biologically active. Thus, in order to determine the ability of a soil to support biological activity and …

Is Carbon Risk Priced In The Cross Section Of Corporate Bond Returns?, Tinghua Duan, Frank Weikai Li, Quan Wen

Research Collection Lee Kong Chian School Of Business

This article examines the pricing of a firm’s carbon risk in the corporate bond market. Contrary to the “carbon risk premium” hypothesis, bonds of more carbon-intensive firms earn significantly lower returns. This effect cannot be explained by a comprehensive list of bond characteristics and exposure to known risk factors. Investigating sources of the low carbon alpha, we find the underperformance of bonds issued by carbon-intensive firms cannot be fully explained by divestment from institutional investors. Instead, our evidence is most consistent with investor underreaction to the predictability of carbon intensity for firm cash-flow news, creditworthiness, and environmental incidents.

Gamification For Air Quality Education: A Systematic Literature Review, Abdollah Baghaei Daemei, Ruggiero Lovreglio, Zhenan Feng, Daniel Paes, Clayton Miller

Research Collection College of Integrative Studies

Air quality is crucial to our health and well-being, as poor air quality can lead to serious health problems such as asthma, allergies, and other respiratory conditions. Educating people about air quality is key to improving awareness and taking action to reduce its negative effects. Gamification offers a creative and engaging way to deliver educational content by incorporating game elements into the learning experience. However, despite its potential, there has been no review of how gamification has been used for air quality education. Thus, this review aims to fill that gap by systematically examining how gamification is applied to air …

Construction Of Electrically Heated Pavement Using Recycled Waste Rubber Tires, Islam M. Radwan, Mohamed Abdel-Raheem

Civil Engineering Faculty Publications

Accumulated snow on roads presents a dual risk of accidents and financial losses. Conventional de-icing methods, which rely on chemicals, salt, and heavy machinery, are unsustainable and detrimental to both the environment and infrastructure. Furthermore, they demand significant labor and pose hazards in densely populated areas. In response, heated pavement systems such as hydronic and electrically conductive concrete (ECON) have gained traction for mitigating snow accumulation on roads. However, the use of carbon fiber and carbon black in ECON raises costs and depletes valuable resources. This research introduces an inventive and sustainable approach to address snow accumulation on rigid pavements …

In recent years, the misuse of antibiotics has led to severe pollution in water environments, with excessive residues in lake water damaging ecosystems and promoting the emergence of antibiotic-resistant bacteria. Therefore, rapid detection of antibiotic residues in the environment is crucial. This study introduces a novel method for the simultaneous quantification of mixed antibiotics in lake water using Surface-Enhanced Raman Scattering (SERS) combined with deep learning methods. To demonstrate the accuracy of our experiments, we tested four lake water samples collected from four distinct sampling points of an artificial lake in a municipal city in China. We independently analyzed each …

A Holistic Marine Biosecurity Risk Framework That Is Inclusive Of Social, Cultural, Economic And Ecological Values, Marnie L. Campbell, Chad L. Hewitt

Research outputs 2022 to 2026

Effectively managing non-indigenous marine species risks demands swift, transparent decisions amid limited data and in an environment where conflicting interest across environmental, economic, social, and cultural realms exists. Conventional risk assessment tools often fail to comprehensively evaluate these risks together, leading to stakeholder dissatisfaction, conflicts and poor biosecurity outcomes. To address this, we present a structured 7-step marine biosecurity risk framework. It systematically assesses incursion's ecological, economic, social and cultural impacts, encourages stakeholder engagement and promotes inclusive decision-making. Steps include defining contexts, setting objectives, estimating consequences, determining management options, evaluating trade-offs, implementing decisions, and communicating risks effectively. A simulation using …
