Effect of Uncertainty on Water Distribution System Model Design Decisions
(American Society of Civil Engineers, 2009)The goal of calibrating a water distribution model is to establish a numerical model that represents the real system. Given the uncertainty in field data, recent studies have examined model parameter and predictive ... -
Efficient Groundwater Remediation System Designs with Flow and Concentration Constraints Subject to Uncertainty
(American Society of Civil Engineers, 2009)A nested optimization problem that utilizes a multiscenario approach based upon a method known as robust optimization is employed to determine a groundwater remediation design that considers the uncertainty in the hydraulic ... -
Limitations of Network Flow Algorithms in River Basin Modeling
(American Society of Civil Engineers, 2009)A number of computer models for river basin planning and management have been developed by various agencies and used extensively since the mid-1970s. Most of the early developments have been based on the use of heuristic ... -

Negotiation Support for Cooperative Allocation of a Shared Water Resource: Methodology
(American Society of Civil Engineers, 2009)The negotiation support system (NSS) proposed in this paper is designed to aid two parties in their negotiations for allocation of water from a shared water resource. The NSS has several components which are activated in ... -
Design of a Water Transmission Pipeline with an Analytical Probabilistic Model
(American Society of Civil Engineers, 2009)A challenge that utilities face is to design new water transmission systems with incomplete information concerning future water demand. With an increase in water demand caused by population and economic growth, a design ... -
Deterministic versus Stochastic Design of Water Distribution Networks
(American Society of Civil Engineers, 2009)The paper describes a procedure for the robust design of water distribution networks which incorporates the uncertainty of nodal water demands and pipe roughness in a multiobjective optimization scheme aimed at minimizing ... -
Water Rationing Model for Consequence Minimization of Water Infrastructure Destruction
(American Society of Civil Engineers, 2009)This paper describes a model developed for optimizing water supply plans for water customers when a water network is partially operational due to the destruction of water networks by malicious attacks or any catastrophic ... -
Up or Out?—Economic-Engineering Theory of Flood Levee Height and Setback
(American Society of Civil Engineers, 2009)Levee setback (location) and height are important issues in flood levee system design and modification. This paper derives an economic-engineering theory of the optimal trade-off of levee setback for height both for original ... -
Evaluation of the Duration of Storm Effects on In-Stream Water Quality
(American Society of Civil Engineers, 2009)One of the primary reasons water-quality standards are not met is the effect of storm runoff and combined sewer overflows. A methodology is presented here to determine the duration of storm effects on stream water quality. ... -
Optimization Model for Integrated Regional Wastewater Systems Planning
(American Society of Civil Engineers, 2009)The wastewater generated in urban areas is one of the main sources of water pollution, particularly in regions characterized with large population density and high urbanization degree. In this paper, we present an optimization ... -
Fuzzy Neural Network Modeling of Reservoir Operation
(American Society of Civil Engineers, 2009)The present study aims at the application of the hybrid model, which consists of artificial neural network and fuzzy logic in the reservoir operating policy during critical periods. The proposed hybrid model [fuzzy neural ... -
Extended Period Simulation Analysis Considering Valve Shutdowns
(American Society of Civil Engineers, 2008)Planned (e.g., regular maintenance) and unplanned (e.g. pipe burst) interruptions occur regularly in water distribution systems leading to their reduced performance. This paper presents an extended period simulation model ... -
Standard Interactive Genetic Algorithm—Comprehensive Optimization Framework for Groundwater Monitoring Design
(American Society of Civil Engineers, 2008)Optimization for water resources management typically requires many simplifying assumptions about the definition and characteristics of the policy or design application in order to express decision makers’ criteria as ... -
Limits to Water Privatization
(American Society of Civil Engineers, 2008)Water allocation under conditions of water scarcity is a looming issue that threatens the economic well being and quality of life of many of the world’s people. Although the causes of water scarcity are varied, many assert ... -
Extended Global-Gradient Algorithm for Pressure-Dependent Water Distribution Analysis
(American Society of Civil Engineers, 2009)Conventional water distribution models are formulated under the assumption that water consumptions or demands defined at nodes are known values, allowing nodal hydraulic heads and pipe flows to be determined by solving a ... -
Efficient Multiobjective Storm Sewer Design Using Cellular Automata and Genetic Algorithm Hybrid
