Water Supply Yield Analysis for Washington Metropolitan Area
Publisher: American Society of Civil Engineers
Abstract: The Washington D.C. Metropolitan Area (WMA) has experienced rapid population growth in the 1980s. Water supply yield analysis techniques are developed in this paper to assess adequacy of the current WMA water supply system ...
Conditional‐Yield Operating Rules for Low‐Flow Management
Publisher: American Society of Civil Engineers
Abstract: A family of reservoir operating rules, termed
Synergistic Bacterial Inactivation by Silver Ions and Free Chlorine in Natural Waters
Publisher: ASCE
Abstract: Using high amounts of chlorine to disinfect contaminated natural waters for drinking purposes can produce an unpleasant taste and odor and contribute to the formation of toxic byproducts. These challenges can be addressed ...
Proteinate-Capped Silver Nanoparticle Transport in Water-Saturated Sand
Publisher: American Society of Civil Engineers
Abstract: The transport of proteinate-capped silver nanoparticles (AgNPs) was evaluated in well-defined water-saturated Ottawa sand over a range of water chemistry conditions and sand particle sizes. AgNP retention in the columns ...
Effects of Flood Control Structures on Flood Response for Hurricane Floyd in the Brandywine Creek Watershed, Pennsylvania
Publisher: American Society of Civil Engineers
Abstract: Small watersheds in urbanizing and suburbanizing regions are an increasingly important element of the flood hazard problem in the United States and abroad. This paper presents a methodology to estimate flood response in ...
Benzene Transport through Landfill Liners Containing Organophilic Bentonite
Publisher: American Society of Civil Engineers
Abstract: The mineral surface of Wyoming bentonite was modified by replacing inorganic ions by different quaternary ammonium compounds of known molecular structure by an ion‐exchange process. The resulting organically modified ...
Protozoa and Virus Disinfection by Silver- and Copper-Embedded Ceramic Tablets for Water Purification
Publisher: ASCE
Abstract: Point-of-use water treatment (PoUWT) technologies have been shown to reduce incidences of waterborne diseases. However, their effectiveness is limited against the most harmful pathogens, such as protozoa and viruses, due ...
Runoff Reduction by Four Green Stormwater Infrastructure Systems in a Shared Environment
Publisher: ASCE
Abstract: Green stormwater infrastructure (GI) imitates the hydrology of undeveloped land to mediate the impacts of stormwater runoff, but research is lacking that characterizes the performances of different types of independent GI ...
Evaluation of a Prediction Model for Influent Pharmaceutical Concentrations
Publisher: American Society of Civil Engineers
Abstract: This research attempts to evaluate a previously developed model for predicting influent concentrations of prescription pharmaceuticals and understand why some drugs are more accurately predicted than others. It also ...
Environmental Life-Cycle Assessment of Winter Maintenance Treatments for Roadways
Publisher: American Society of Civil Engineers
Abstract: Departments of Transportation (DOTs) rely heavily on chloride-based treatments for winter road maintenance despite the well-documented effects of these chemicals on infrastructure and the environment. Proposed alternative ...
