Permits, Surface Water/Groundwater Baseline Sampling, and Analysis of Dewey-Burdock In Situ Uranium Project in Fall River County, South Dakota
Powertech Uranium Corporation has proposed to conduct in situ mining within a uranium enriched ore deposit on the proposed permit area known as the Dewey-Burdock project. The project is...

Groundwater Transport Modeling Using Fuzzy Sets and Fuzzy Logic
Modeling of groundwater flow and transport is inherently uncertain. The predictive capability of the model depends upon both the quantity and quality of hydrogeologic data. The introduction...

Remediation System Optimization with Alternatives
This work applies the enhanced multi-objective robust genetic algorithm (EMRGA) (Beckford and Chan Hilton, 2004) to Fort Ord's Site OU2 for optimal groundwater remediation under uncertainty....

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...

Advances in Watershed Management and Fluvial Hazard Mitigation Using Artificial Neural Networks and Remote Sensing
Watershed and channel management across spatial and temporal scales requires an informed, interdisciplinary approach by experts and stakeholders, who often have disparate goals and objectives....

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...

Flood Warning System for the Sutlej River in Remote Northern India
Through a collaborative effort of the Central Water Commission (CWC) of India, the U.S. Agency for International Development (which provided funding for the project), Riverside Technology,...

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...

Pioneer Square Areaways
Pioneer Square, one of the earliest neighborhoods in Seattle, is adjacent to Elliott Bay. Much ofthis part of the city originally was built on existing land that used to get flooded. When...

The Role of Aesthetics in Bridge Design
The role of aesthetics in current bridge design practice varies widely. Many bridgeprojects in the United States are developed without including aesthetics as one of theproject goals....
