Numerical Methods for Modeling Water Quality in Distribution Systems: A Comparison
(American Society of Civil Engineers, 1996)A comparison is made between the formulation and computational performance of four numerical methods for modeling the transient behavior of water quality in drinking-water-distribution systems. Two are Eulerian-based (the ... -
Water Crisis in Developing World: Misconceptions about Solutions
(American Society of Civil Engineers, 1996)The United Nations forecasts a world population growth of 1 billion in the next decade and 2 billion in the next two decades—growth that will place immense demands on the developing nations' water resources. The extent of ... -

Yields from Ground-Water Storage for California State Water Project
(American Society of Civil Engineers, 1996)Yields from a proposed ground-water storage facility are evaluated using a nonlinear optimization model of the California State Water Project (SWP) and the Central Valley Project (CVP). Model constraints account for the ... -
Key Sources of Uncertainty in QUAL2E Model of Passaic River
(American Society of Civil Engineers, 1996)Application of stream water-quality models in decision making has been hampered by a lack of data appropriate for minimization of model-simulation uncertainty. A method for determining data needed to reduce model-prediction ... -
Use of Geographic Information Systems in Ground-Water Flow Modeling
(American Society of Civil Engineers, 1996)Geographic information systems (GISs) offer data management and spatial analysis capabilities that can be useful in ground-water modeling. Many regional ground-water models require large, unwieldy data sets, and calibrating ... -
Chebyshev Model for Water-Quality Management
(American Society of Civil Engineers, 1996)A Chebyshev criterion is used to develop robust direct regulation water-quality management models. The reserve capacity of the stream, in terms of the excess capacities above the water-quality goal at the most critical ... -
Maximized Detention Volume Determined by Runoff Capture Ratio
(American Society of Civil Engineers, 1996)The percentage of storm-water runoff volume, or of the number of runoff events captured is a key factor when designing storm-water quality control facilities. Design criteria originally developed for sizing flood control ... -
Storm-Water Utility User Fee Credits
(American Society of Civil Engineers, 1996)Urban storm-water utilities are an important funding method for storm-water programs. The rate structure is the basis on which the utility forms its fees and other secondary funding methods and rate modifiers. One rate ... -
Watershed Riparian Management and Its Benefits to a Eutrophic Lake
(American Society of Civil Engineers, 1996)Sediment and nutrient loads from a 73 km -
Adaptive Search Optimization in Reducing Pump Operating Costs
(American Society of Civil Engineers, 1996)This paper proposes a method called the adaptive search algorithm to optimize a water supply system. The adaptive search algorithm is a discrete optimization search model that selects which pumps to switch on or off using ... -
Experiment with Simulation Models in Water-Resources Negotiations
(American Society of Civil Engineers, 1996)A laboratory experiment was conducted to investigate the effects of various kinds of access to a simulation model on water-resources negotiation outcomes and processes. The (mock) negotiation involved determining a release ... -
Regression and Inverse Analyses in Regional Ground-Water Modeling
(American Society of Civil Engineers, 1996)Numerical models of ground-water flow within the regional aquifer underlying Lambton County, Ontario, Canada, are constructed by the conjunctive application of methods of regression and inverse analyses. Regression analysis ... -
Predicting Sediment Yield in Storm-Water Runoff from Urban Areas

Intensity, Duration, and Frequency of Residential Water Demands
(American Society of Civil Engineers, 1996)Water demands at four single-family residences were monitored for a 1-yr period. About 8,000 demands per capita were recorded and converted to single equivalent rectangular pulses. Each pulse was classified by type ... -
Optimal Dispersed Ground-Water Contaminant Management: MODCON Method
(American Society of Civil Engineers, 1995)A presented methodology and model compute optimal ground-water use strategies that approximate optimality for water supply, while achieving desired ground-water quality goals. This MODCON approach utilizes a new goal ... -
Water-Price Effect on Residential and Apartment Low-Flow Fixtures
(American Society of Civil Engineers, 1996)The relationship between water price and the installation of low-flow faucets, low-flow toilets, low-flow showerheads, and drip irrigation of plantings was analyzed for apartments and individual households in Tucson, Ariz. ... -
Neural-Network Models of Rainfall-Runoff Process
(American Society of Civil Engineers, 1995)Spatially distributed rainfall patterns can now be detected using a variety of remote-sensing techniques ranging from weather radar to various satellite-based sensors. Conversion of the remote-sensed signal into rainfall ... -
