Climate Resilient Infrastructure: The Problem Shift, Tyler Lautieri, Isaiah Morrison, Harrison Totten

Discovery Day - Daytona Beach

Climate change is a heavily debated topic, but recent studies and data show that climate change is leading to an increase in the frequency and severity of hazards. Infrastructure systems are subjected to more compound and cascading events that lead to the degradation of the systems. More traditional infrastructure design relies on concern that the system will be subjected to single hazard issues, and the design focuses on preventing structural failure during these isolated events. These approaches often fail to account for long term degradation of the system, as well as the interacting hazards, and system interdependence, which makes resilience …

Evaluation Of Dredged Sediments As A Partial Replacement For Fine Aggregate In Mortar And Concrete, Ashish Gautam

Graduate Theses and Dissertations (2019 - present)

The feasibility of using dredged sediment from the Mobile River as a partial replacement for fine aggregate in mortar and concrete was investigated through a series of laboratory characterization and performance evaluation. Three dredged sediment samples (A, B and C) were initially examined, and Sample A was selected for further evaluation due to its closer resemblance to natural fine aggregate. This sample exhibited lower moisture content, higher sand equivalent values, higher specific gravity, and lower absorption. Mortar mixtures with 0, 10, 20, 30, 50, 75 and 100% dredged sediment replacement showed decreasing workability as the replacement level increased. The 20% …

Machine Learning For Predictive Energy And Emissions Modeling Of Vehicles And Power Grids In The United States, S M Tanvir Faysal Alam Chowdhoury

Dissertations

The environmental benefits of electric vehicle (EV) adoption depend on more than replacing internal combustion engine vehicles with electric powertrains. EV adoption reshapes electricity demand, interacts with regional generation mixes, and influences travel behavior and congestion, creating a coupled transportation-energy system in which vehicle and power-plant emissions must be evaluated together. This dissertation develops machine-learning frameworks for predicting energy consumption and emissions from vehicles and power grids under rising EV adoption. The first component forecasts grid emissions from EV charging. Using simulation data from NREL's Cambium database, a Prophet-based time-series framework predicts carbon dioxide, nitrous oxide, and methane emission rates …

Synthesis And Characterization Of Carbon Quantum Dots And Gold Nanoparticles For Norovirus Biosensing Applications In Water Systems, Breanne Evans

Master's Theses

Rapid, reliable detection of viral pathogens remains a significant challenge across water-treatment and environmental monitoring systems, including drinking-water, wastewater, water reuse, and environmental surveillance applications. Waterborne viral contamination can pose substantial public-health risks, making early detection essential for protecting water quality and responding quickly to treatment failures or contamination events. Direct potable reuse (DPR) is one particularly demanding example because it requires continuous verification of treatment performance and the broader need for rapid virus monitoring extends across many water-treatment and environmental surveillance applications. Norovirus is a priority target because of its widespread occurrence in wastewater, environmental persistence, and exceptionally low …

Inconsistencies Emerge Between Regional And Local-Scale Water Security Metrics At Military Installations, Abigail Birnbaum, Michael L. Berg, Caitlin Grady, Daniel J. Weeks, Christopher M. Chini

Faculty Publications

Recent United States federal policy for military installations has emphasized the importance of developing a standardized approach for water security assessment to monitor changes in water resources and the ability for an installation to meet both its civilian and mission needs. For military installations in the United States, these assessments must consider demands both inside and outside the installation’s fence line, as regional resources are required to meet mission readiness. Focusing on physical water scarcity, this study compares four water security metrics with unique formulations and spatial resolutions, including an installation-scale metric and multiple regional metrics defined for either baseline …

Model Stormwater Standards 2026, Unh Stormwater Center

UNH Stormwater Center

The purpose of post-construction stormwater management standards is to provide reasonable guidance for the regulation of stormwater runoff to protect local natural resources from degradation and prevent adverse impacts to adjacent and downstream land, property, facilities, and infrastructure. These standards regulate discharges from stormwater and runoff from land development projects and other construction activities to control and minimize increases in stormwater runoff rates and volumes, soil erosion, stream channel erosion, and nonpoint source pollution associated with stormwater runoff.

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

The climate question 

• Overtopping = 1/3^rd of all dam failures (ASDSO) 
• Drought concerns and supply uncertainty motivate keeping reservoirs full 
• Overtopping likelier if extreme storm when reservoir full 
• Over much of the country the probability of the annual daily maximum rainfall > 100-year event and the preceding 30-day rainfall >10-year event are going up (Hwang & Lall 2024)

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 …
