Levels of Service Applied to Urban Streams
(American Society of Civil Engineers, 1991)The idea of levels of service for resource allocation is explored in managing troublesome urban collector streams in Charlotte, N.C. Results suggest that a classification system based on levels of service would be of ... -
System Analysis of Water Treatment Plant in Taiwan
(American Society of Civil Engineers, 1991)This paper presents an application of a system analysis tool to evaluate the design and operation of a water treatment plant in Taiwan. The optimal design and operation problem is posted as a nonlinear programming problem ... -
Optimal Stochastic Operation of Salt River Project, Arizona
(American Society of Civil Engineers, 1991)The application of extended linear quadratic Gaussian (ELQG) control, a nonlinear stochastic optimization method, to the Salt River Project reservoir system is described. The optimization problem was posed as the maximization ... -
Discussion of “<i>Aqueduct and Reservoir Capacities for Distribution Systems</i>” by Lawrence E. Flynn and Miguel A. Mariño (September, 1989, Vol. 115, No. 5)
(American Society of Civil Engineers, 1991) -
Model Aggregation for California State Water Project
(American Society of Civil Engineers, 1991)The Delta‐O'Neill simulation model (DELMOD) combines the results of the three models used for operating the California State Water Project (SWP) facilities south, north, and west of O'Neill Forebay. Network flow programming ... -
Estimation of Maximum Cut‐Set Size for Water Network Failure
(American Society of Civil Engineers, 1991)Assessment of the reliability of a water distribution system through evaluation of all possible combinations of mechanical (pipe) failure is computationally intensive. It is nonpolynomial (NP) hard. An approach is proposed ... -
Estimation of Inundation in Open‐Cast Limestone Mine in Kerala, India
(American Society of Civil Engineers, 1991)Data on rainfall, runoff, water table fluctuation, and subsurface geology are obtained in an open‐cast limestone mine in Kerala, India. These data are analyzed to identify the most critical condition during the full life ... -
Knowledge‐Based System for SWMM Runoff Component Calibration
(American Society of Civil Engineers, 1991)A knowledge‐based system for automating the calibration of the runoff model of the widely used storm water management model (SWMM) is described. The paper focuses on the key components of the knowledge‐based system: (1) ... -
Water Supplies and Nationwide Drought of 1988
(American Society of Civil Engineers, 1991)Findings of a survey about experiences managing public water supplies during the drought of 1988 are reported. Responses were obtained from 408 of the 501 large utilities in the United States to whom the questionnaire was ... -
Stochastic Optimization of Multiple‐Reservoir‐System Operation
(American Society of Civil Engineers, 1991)A stochastic dynamic programming model for the optimization of hydropower prroduction of a multiple storage‐reservoir system with correlated inflows has been developed. Application was made to a subsystem of the Brazilian ... -
Recurrence Interval of Geophysical Events
(American Society of Civil Engineers, 1991)The recurrence interval is the expected length of time intervening between consecutive geophysical events. The interest in this work is in episodic (catastrophic or cataclysmic) phenomena such as large floods or rare ... -
Method for Locally Adapted Water‐Pollution Abatement in Lake Mjøsa, Norway
(American Society of Civil Engineers, 1991)In the past, the effects of pollution abatement were measured in terms of the size of reductions achieved. This paper demonstrates a method that can be used to measure effects in relation to the practical significance of ... -
Network Flow Modeling of Oroville Complex
(American Society of Civil Engineers, 1991)Network flow programming (NFP) is used to simulate the operation of the Oroville reservoir system of the California State Water Project (SWP). The simulation uses three integrated NFP models developed and calibrated to ... -
Closure to “<i>Water Requirements versus Water Availability in Saudi Arabia</i>” by Omar S. Abu Rizaiza and Mohamed N. Allam (January, 1989, Vol. 115, No. 1)
(American Society of Civil Engineers, 1991) -
Identification of Aquifer's Well‐Pumpage Histories
(American Society of Civil Engineers, 1991)A methodology is developed that estimates the parameters and the past pumping or recharge history of an aquifer simultaneously. A maximum likelihood procedure is used to estimate the aquifer's parameters in conjunction ... -
Prototype Decision Support System for Analyzing Impact of Catchment Policies
(American Society of Civil Engineers, 1991)The South Australian government has recently formed a committee to investigate conflicts over the use of resources in the Mt. Lofty Ranges, including improvements to the quality of water supplied to the city of Adelaide. ... -
Using Regional Ground‐Water Model in Water Resource Planning
(American Society of Civil Engineers, 1991)Nassau County, New York is presently developing a water management plan. In addressing the fundamental question of the ability of the aquifer to yield sufficient quantities of water for public supply, two approaches have ... -
Reliability‐Based Distribution System Maintenance
(American Society of Civil Engineers, 1991)A strategy for prioritizing decisions for the maintenance of a water distribution system is developed. Using component and network reliability based on time‐varying connectivity concepts, the probabilities that water will ... -
Output Reliability as Guide for Selection of Rainfall‐Runoff Models
(American Society of Civil Engineers, 1991)Selection of rainfall‐runoff models is dependent on the modeling objectives and the simulation accuracy required. Output reliability is proposed as a measure to help in choosing the appropriate model for a given rainfall‐runoff ... -
