What Makes Smart Irrigation Work? Lessons From Producers In The Upper Colorado River Basin, Tejinder Singh, Matt Yost, Elisa Flint, Burdette Barker, Jessica Ulrich-Schad, Silas Ekadu

Spring Runoff Conference

Colorado River Basin Water Crisis

• Water allocations in the Colorado River Basin were set during wetter periods and now exceed current river flows, creating a gap between water supply (12.5 maf yr^-1) and demand (15 maf yr^-1).
• River flow has declined 19% since 2000.

Making Water Visible: Neutral, Verification-First Infrastructure For Basin-Scale Water Accountability, Eric Mcculley

Spring Runoff Conference

Every Tool Tells You What the Lake Level WAS.

None Tell You What It WILL BE.

• Current monitoring is retrospective — USGS gauges and DWR reports show only historical data
• Decision lag: By the time you see the problem, it’s too late to adjust
• 2024–2025 season: GSL dropped to record lows before upstream conservation kicked in
• Agricultural users, municipalities, and GSL all compete for limited supply with imperfect information

Leasing Water For Great Salt Lake: Water Savings And Producer Impacts, Conner Harwood

Spring Runoff Conference

Great Salt Lake Water Leasing

• Utah is working to increase inflows to GSL through voluntary water leasing from agriculture
• But key information is missing:
• How much water can leases save at the field level?
• At what price should farmers be compensated?
• This project:

1. Estimates field-level consumptive water use
2. Estimates the value of water in agricultural production
3. Evaluates water savings and producer impacts across leasing strategies

Remediation Of Ammonium Perrhenate Via Tris(2,2’-Bipyridine)Ruthenium(Ii) Chloride, Kaylin L. Thomas, Sandra A. Abdellah, Alvin A. Holder

Knowledge and Creativity Expo

Pertechnetate (TcO₄⁻) is a persistent radioactive byproduct resulting from the decay of uranium-235 or plutonium-239 in the nuclear fuel cycle. Its high environmental mobility, long half-life, and significant beta radiation make TcO₄⁻ a critical contaminant. Structurally tetrahedral and water-soluble, TcO₄⁻ behaves similarly to the sulfate anion, facilitating its rapid introduction into ecosystems.

It bioaccumulates in lower-level organisms, propagating radioactive and toxic effects through food chains. In mammals, technetium-99 accumulates in the thyroid and may also impact fetal development. Its small charge, chemical stability, and solubility present significant challenges for effective remediation.

Current remediation methods often suffer from poor selectivity, dependence …

Reconstructing 5000 Years Of Hurricane Activity In Holyrood Pond Using Sediment Core Analysis, Jamie Mclaulin, Arielle Nogueira, Elizabeth Wallace

Knowledge and Creativity Expo

Hurricanes are hazardous and costly events that annually negatively impact people that live in coastal areas in North America.  The current observational record of hurricanes is short (1970- present) and does not offer insight into the effects of climate change on hurricane frequency.  One method of improving and extending our observational record of hurricanes is to reconstruct paleohurricanes using sediment cores.  These cores record hurricane activity in the form of coarse-grained overwash layers that are deposited when hurricanes move sand from beaches into backbarrier ponds.  In this project, we analyzed sediment cores from Atlantic Canada to locate coarse-grained storm layers …

Methane Consumption Rates By Coastal Virginia Beach Microbes, James R. Bailey Ii

Knowledge and Creativity Expo

This study measures whether microbial communities in the shallow coastal waters of Virginia Beach are capable of consuming methane in the water column. Using methane enrichment incubations and gas chromatography, we found no measurable methane oxidation of our samples over multi-day periods. These results suggest that these coastal waters may act as net sources of atmospheric methane.

Is The Chesapeake Bay Browning?, Samantha Williamson, Jessie Turner

Knowledge and Creativity Expo

Brownification is when water bodies turn brown over time. It occurs due to high amounts of color-dissolved organic matter (CDOM). CDOM is organic material, such as decaying leaves and organisms, that leaches into the water column like tea. It absorbs ultraviolet and blue light more than red light, causing the water to appear brown. After comparing surveys from 1987 and 2018, scientists discovered the Adirondack lakes underwent brownification as they recovered from acid rain. However, while increased CDOM can signify an ecosystem’s recovery, it can also hinder seagrass growth. Although scientists have studied this phenomenon in lakes, estuaries have not …

Living Shorelines As A Solution To Saltwater Marsh Erosion, Elizjah Eddy, Richard Hale

Knowledge and Creativity Expo

In recent years, saltwater marshes fringing the Lafayette River, a tributary of the Elizabeth River, have experienced degradation in response to increased inundation and ocean energy . These marshes provide critical ecological and economic benefits to the City of Norfolk, and prioritizing their long term health and sustainability is an important challenge. An emerging restoration tactic involves enhancing marsh elevation through the application of dredge material that would otherwise require disposal offshore (known as thin-layer placement or TLP). An important first step in TLP projects is characterizing the textural and geochemical properties of the existing marsh sediment. The goal of …

How Much Does Shape Matter: Investigating The Impact Of Marine Particle Morphological Features On In-Situ Settling Velocities Using Pca And Various Ml Models, Huanqing Huang, Alexander B. Bochdansky

Knowledge and Creativity Expo

Particle settling velocity serves as an essential component in ocean biological pump, as it determines particle retention time in the water column. Stokes’ law has been widely used to predict particle settling velocities by particle size and excess density in aquatic environments. However, an increasing number of studies suggest that Stokes’ law fits poorly in the size-velocity relationship of observations on small oceanic particles. Here, we present a series of novel approaches to investigate the relative contribution of settling velocities by the particle shape and optical densities using machine learning (ML) models and principal component analysis (PCA), based on 3906 …

Initial Development Of Cooperative Aerial And Ground Vehicles Experimental Testbed, Javier S. Robinson, Morad Nazari

Beyond: Undergraduate Research Journal

Heterogeneous multi-agent systems represents a growing area of research in autonomous vehicles, which involves the real-time cooperation of vehicles operating under different roles or dynamical mod- els. While there is plenty of theoretical work, the existing experimental research focuses on cooperation between physically identical vehicles. This is likely because testing heterogeneous vehicles naturally in- volves more complicated dynamics and communication frameworks to ensure compatibility. The goal of the Cooperative Aerial and Ground Vehicles Experimental (CAGE) testbed is to develop an experimen- tal testbed that involves cooperation of two distinct vehicle models: multiple Crazyflie 2.1 quadcopter drones and at least one …

Water Needs And Recovery Pathways For The Great Salt Lake, David Tarboton, Sarah Null, Bethany Neilson

Spring Runoff Conference

Main Points 

• Levels of GSL inherently fluctuate because of variability in precipitation and temperature that drive inflow and evaporation 
• Reductions in inflows due to water use are superimposed on this variability 
• Consistent delivery of conserved water offers the opportunity to shift the range of lake levels upwards reducing the occurrence of serious adverse effects and increasing the potential for healthy lake levels 
• Adding 250 thousand-acre ft/year reduces the occurrence of serious adverse effects from 61% to 28% over the long term 
• Adding 800 thousand-acre ft/year shifts the mean of variable lake levels to the lower end of the healthy lake …

Wearer Speech Authentication Using Correlated Acoustic And Body-Vibration Data, Tyler Gore, Aaron Rudolph, Sharath Ananth

Defensive Publications Series

Continuously-operating microphones on wearable computing devices (e.g., a smartwatch, augmented reality glasses, smart ring, etc.) may present challenges related to power consumption and user privacy, as well as difficulty in distinguishing a wearer's speech from ambient sounds. A disclosed technique can address these challenges through a bimodal sensing approach that concurrently analyzes air-conducted acoustic signals from a microphone and body-conducted kinetic signals from a motion sensor, such as an accelerometer or gyroscope. A processing system may perform a correlation analysis between features extracted from the acoustic data and the kinetic data to determine if a detected sound originates from the …

Hierarchical Multi-Agent Orchestration For Cross-Domain Root Cause Analysis, Sandeep Kumar

Defensive Publications Series

Performing root cause analysis for cross-domain issues, such as cascading failures in complex, fragmented software ecosystems, can be challenging due to siloed data and technical complexity. To address this, a hierarchical multi-agent orchestration architecture is described. The system can utilize a central orchestrator agent (OA) that receives a diagnostic query, decomposes it into sub-hypotheses, and dynamically routes these tasks to specialized subject matter expert (SME) agents. Each SME agent can be configured with domain-specific knowledge and tools to investigate its assigned task. Through an iterative execution loop, the OA analyzes intermediate findings from the SME agents and can trigger further …
