Optimizing River Diversion under Hydraulic and Hydrologic Uncertainties
(American Society of Civil Engineers, 1994)Flood diversion during dam construction has a major influence on the construction period, and its cost represents a significant part of the total project cost. In general, selection of diversion system capacity and the ... -
Evaporation and Evapotranspiration under Climate Change in New England
(American Society of Civil Engineers, 1994)Methods to estimate and generate free‐surface evaporation -
Market Models, Protest Bids, and Outliers in Contingent Valuation
(American Society of Civil Engineers, 1994)Responses to willingness‐to‐pay questions in contingent valuation (CV) surveys are being used with increasing frequency to obtain estimates of the value of public goods, such as improved water quality, for use in benefit‐cost ... -
Optimal Pump Operations Considering Pump Switches
(American Society of Civil Engineers, 1994)A methodology for determining optimal pump operation schedules for water‐distribution systems is presented. In addition to minimizing the energy‐consumption cost, the model includes a constraint to limit the number of pumps ... -
Bromine Distribution Factors in THM Formation
(American Society of Civil Engineers, 1994)Trihalomethanes (THMs), a group of drinking water disinfection by‐products, are suspected carcinogens and are currently regulated by the U.S. Environmental Protection Agency. More stringent regulation of individual and ... -
Partial Infeasibility Method for Chance‐Constrained Aquifer Management
(American Society of Civil Engineers, 1994)A pump‐and‐treat system of extraction wells is modeled to create a hydraulic capture zone to immobilize a plume of contaminants in a confined aquifer with uncertain hydraulic transmissivity. The stochastic approach is used ... -
Data Management for Large‐Scale Water‐Distribution Optimization Systems
(American Society of Civil Engineers, 1994)This paper presents a technique to efficiently process data to supply the necessary in‐puts to a large‐scale water‐distribution optimization model. The overall goal of this project is to develop an on‐line optimal control ... -
Assessing Nassau County's Water Conservation Program
(American Society of Civil Engineers, 1994)To assess the effectiveness of Nassau County's water conservation program, the effects of population changes and weather patterns on water use must first be screened out. Using multiple linear regression, an equation was ... -
Demand‐Driven Operation of Reservoirs Using Uncertainty‐Based Optimal Operating Policies
(American Society of Civil Engineers, 1994)In this study a demand driven stochastic dynamic programming (DDSP) model is developed that allows the use of actual variable monthly demand in generating the operating policies. In DDSP, the uncertainties of the streamflow ... -
Alluvial Fan: Proposed New Process‐Oriented Definitions for Arid Southwest
(American Society of Civil Engineers, 1993)The Flood Control District of Maricopa County, Arizona, recently completed a study whose purpose was to select and describe four alluvial fans for instrumentation and long‐term monitoring. One primary result of this study ... -
Land Use, Climate, and Water Supply
(American Society of Civil Engineers, 1993)A Monte Carlo simulation experiment was conducted to explore the relationships between land use, climate, and water supply yields. A watershed streamflow and sediment yield model was coupled with a reservoir model and used ... -
Parameter Estimation of Linear and Nonlinear Muskingum Models
(American Society of Civil Engineers, 1993)The conventional method of parameter estimation of Muskingum flood‐routing models is based on a graphical bivariate curve‐fitting procedure. The subjectivity of this procedure may lead to problems of reproducibility. A ... -
Optimal Operation of Multiquality Networks. I: Steady‐State Conditions
(American Society of Civil Engineers, 1993)A model is developed for optimal operation of a multiquality water‐supply system, under steady‐state conditions. The system contains: sources of different qualities, treatment facilities, pipes, and pumping stations. The ... -
Drainage Water Disposal, Jeddah, Saudi Arabia
(American Society of Civil Engineers, 1993)The ground‐water table in four districts of the city of Jeddah, in Saudi Arabia, is to be lowered by installing a subsurface drainage system. In connection with the drainage studies, the pollution potential of the drainage ... -
Forecasting Hourly Water Demands by Pattern Recognition Approach
(American Society of Civil Engineers, 1993)Hourly water‐demand data is forecasted with a model based on a combination of pattern recognition and time‐series analysis. Three repeating segments are observed in the daily demand pattern: “rising,” “oscillating,” ... -
Evaluating Locally Financed Reservoir: The Case of Applewhite
(American Society of Civil Engineers, 1993)In an era when subsidized water development is not available to municipalities, development costs are fully borne by the rate‐paying clientele. Proposed water projects therefore impact consumers both through increased rates ... -
Optimal Operation of Multiquality Networks. II: Unsteady Conditions
(American Society of Civil Engineers, 1993)A model is developed for optimal operation of a multiquality water‐supply network under unsteady conditions, for a time horizon that is divided into a number of time periods. The objective is to minimize total cost, which ... -
