Monitoring and Quantifying Rate-Limited Mass Transfer Using Geoelectrical Measurements
Non-Fickian solute-transport behavior has been observed at research and aquifer remediationsites in diverse geologic settings. Anomalous behavior such as concentration rebound, long breakthrough...
Considerations Regarding Geochemical Transformations Downstream of Subsurface Wastewater Effluent Disposal Facilities
Many suburban and rural communities use subsurface disposal in conjunction with on-site and other small decentralized systems. In addition, to reduce the impacts of wastewater treatment...
Watershed Modeling for Surface-Groundwater Interaction
Groundwater use has increased rapidly due to irrigation development in the Great Plains. This is especially true in the Republican Basin that intersects the three states of Nebraska, Kansas...
Viral Fate and Transport Modeling under Salinity Impact
This research studied the impact of salinity on sorption and transport of MS-2 in saturated sand through one-dimensional column experiments. MS-2 was used as a surrogate to understand...
Evaluation of IA SWAT Testing Protocol for ET Controllers
In recent years the Irrigation Association (IA) has developed a testing protocol for Smart Water Application Technologies (SWAT). These technologies consist of irrigation controllers such...
Enhancing the Solution of Large Monitoring Network Design Problems Using a New Epsilon-Dominance Hierarchical Bayesian Optimization Algorithm
Designing long-term monitoring (LTM) networks for contaminated groundwater is a challenging problem that has long been recognized to suffer from the curse of dimensionality. LTM design...
Concentrated Animal Feeding Operations (CAFOs) and Nitrogen Conversions in the Groundwater Environment
EPA's regulatory focus on concentrated animal feeding operations has historically concentrated on potential surface water impacts from direct discharges as well as nutrient-laden runoff....
Water for Life: Have Improvements in Water and Wastewater Infrastructure along the Rio Grande/Rio Bravo Affected the Lives of Mexico and Texas Border Residents?
Prior to 1990 the poor communities along the Mexico/US border did have not have comparable waterand wastewater infrastructure investments that exist in other US cities. The explosion of...
Summary of Approaches for Estimating Playa Lake Flooding
Playa, or terminal, lakes are common in semi- and arid environments; and their characteristic level, hard, and usually dry surfaces make them ideal for airports, as they are used in the...
A Decision Framework for Stormwater Control in Urbanized Watersheds
Historically, urban growth occurred around water bodies due to factors such as easy access to transportation, water supply, and drainage. With the expanded transportation network along...
Effects of Impervious Area Estimation Methods on Simulated Peak Discharges
The variability of simulated flood discharges is evaluated using two methods for estimating impervious surfaces and common design methods in the Mission Creek watershed (31 sq km) located...
Mitigation of Impervious Surface Hydrology Using Bioretention in North Carolina and Maryland
As an increasingly adopted stormwater best management practice to remedy hydrologic impairment from urban imperviousness, bioretention facilities need rigorous field performance research...
Asphalt Parking Lot Runoff Nutrient Characterization for Eight Sites in North Carolina, USA
The objectives of this study were to characterize asphalt parking lot runoff quality and determine factors influencing nutrient concentrations and loads. Event mean concentrations (EMCs)...
Probabilistic Analysis of Long-Term Aquifer Recharge
Long-term time series of aquifer recharge and other aquifer fluxes (aquifer discharge, groundwater extraction) are essential to monitor and understand aquifer processes. This paper presents...
