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...
