Ground-Arthropod Assemblage Response To Groundwater As A Metric Of Flooding In The Middle Rio Grande, Wesley Noe
Water Resources Professional Project Reports
Riparian zones are dynamic ecosystems, crucial for maintaining biodiversity and ecological balance, particularly in arid environments like the Middle Rio Grande (MRG). Ground arthropods, with their sensitivity to environmental changes, serve as bioindicators for assessing the impacts of water regime changes in the MRG, specifically flooding which was historically the main driver of the MRG ecosystem. This study investigated the responses of ground arthropod communities to fluctuations in groundwater and land management practices within MRG riparian habitats. Using a combination of pitfall trapping and habitat assessments, arthropod abundance was assessed in relation to depth to groundwater (DTG). Findings revealed shifts …

Urban Base Cations: Fate, Transport, And Effect On Nitrogen Cycling Genes In Green Stormwater Infrastructure, Duyen Thuy Lam
Dissertations (1934 -)
Urbanization has significantly changed the natural cycling of base cations, primarily due to the use of deicer salts, such as sodium chloride, and chemical weathering of limestone and concrete infrastructure. An unintended consequence is the accumulation of salt across urban settings. These base cations, transported mainly by stormwater runoff, accumulate in soils, streams, lakes, and groundwater, posing risks to soil health, water quality, and ecosystems. To mitigate stormwater runoff and pollutants, cities have adopted stormwater best management practices, shifting from traditional gray to hybrid gray-green infrastructure. As a result, salt-laden runoff is increasingly routed into green stormwater infrastructure (GSI), where …
Low Dissolved Oxygen Operation Enhances Biological Phosphorus Removal In Wastewater Treatment,

Old Dominion University
Low Dissolved Oxygen Operation Enhances Biological Phosphorus Removal In Wastewater Treatment, Haley Morgan
Civil & Environmental Engineering Theses & Dissertations
Biological phosphorus (bio-P) removal occurs when bacteria are exposed to anaerobic/aerobic conditions that stimulate polyphosphate-accumulating organisms (PAOs) to uptake phosphorus. In most treatment plants, dissolved oxygen (DO) concentrations in the aeration tanks are commonly at or above 2.0 mg O2/L, which is often referred to as the most optimal aeration condition for bio-P. If bio-P can happen efficiently at lower DO (< 0.3 mg O2/L), then the energy demand of aeration can be decreased appreciably. This research was conducted in a biological nutrient removal (BNR) pilot plant to assess the performance of bio-P at progressively lower DO operation. This …

Diverse native vegetation supports the many ecosystem services that wetlands provide to society. In degraded wetlands, the native vegetation often needs to be reseeded or replanted as part of the restoration process. However, such wetland revegetation practices of managers are relatively undocumented and the availability of native plants for wetland restoration from vendors has been unclear. We conducted surveys of wetland managers and wetland native plant vendors in the Intermountain West in 2023 to understand their practices, challenges, and perspectives. We found that wetland managers in the Intermountain West revegetate diverse habitats for important ecosystem services despite very limited budgets …

Watershed Sciences Faculty Publications
As high-frequency sensor networks increasingly enhance data-driven models of water quality, process-based models like the U.S. National Water Model (NWM) are generating accessible forecasts of streamflow at increasingly dense scales. There is now an opportunity to combine these products to construct actionable water quality forecasts. To that end, we couple streamflow forecasts from the NWM to a gradient-boosted decision tree algorithm (LightGBM) trained on 5+ years of high-frequency monitoring data to forecast in-stream turbidity levels in the Catskill Mountains, NY, USA. Results indicate LightGBM models are capable of relatively skillful predictions, which enable robust forecasts for 1–3 days lead times. …

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 …
