Cross Correlation of Demands in Water Distribution Network Design
(American Society of Civil Engineers, 2007)The aim of water distribution design is to size and configure a system so that it meets existing and future demands while providing pressures above a minimum level for service and fire protection. Extended period simulation ... -
Multipurpose Reservoir Operation Using Particle Swarm Optimization
(American Society of Civil Engineers, 2007)This paper presents an efficient and reliable swarm intelligence-based approach, namely elitist-mutated particle swarm optimization (EMPSO) technique, to derive reservoir operation policies for multipurpose reservoir ... -
Generating Alternatives Using Evolutionary Algorithms for Water Resources and Environmental Management Problems
(American Society of Civil Engineers, 2007)Contemporary heuristic search procedures [e.g., evolutionary algorithms (EAs)] continue to offer increased capabilities for systematic search for a range of water resources and environmental management problems. These ... -
Direct Search Approaches Using Genetic Algorithms for Optimization of Water Reservoir Operating Policies
(American Society of Civil Engineers, 2007)The direct search approach to determine optimal reservoir operating policies is proposed with a real coded genetic algorithm (GA) as the optimization method. The parameters of the policies are optimized using the objective ... -
Valve-Controlled Segments in Water Distribution Systems
(American Society of Civil Engineers, 2007)Subsystem identification in water distribution systems is important for repairing pipes and containing damages. In this paper, a method is proposed to identify the smallest subsections of a network called segments that are ... -
Simulation of Intra- or Transboundary Surface-Water-Rights Hierarchies Using the Farm Process for MODFLOW-2000
(American Society of Civil Engineers, 2007)Water-rights driven surface-water allocations for irrigated agriculture can be simulated using the farm process for MODFLOW-2000. This paper describes and develops a model, which simulates routed surface-water deliveries ... -
Influence of Inflows Modeling on Management Simulation of Water Resources System
(American Society of Civil Engineers, 2007)This paper investigates the influence of different hydrological input data on the management simulation of a water resources system (WRS). Three complete simulations were carried out using synthetic inflow series generated ... -
Calibration and Verification of QUAL2E Using Genetic Algorithm Optimization
(American Society of Civil Engineers, 2007)In this study, the QUAL2E model is linked with a genetic algorithm (GA) in order to conduct the calibration and verification of the model. The efficacy of the optimization model was tested for different observation data ... -
Mathematical Programming Approaches for Modeling Water Rights Allocation
(American Society of Civil Engineers, 2007)Three methods for modeling allocation of water rights under different types of water rights systems are presented. The priority-based maximal multiperiod network flow (PMMNF) programming method searches for optimal allocations ... -
Water Sector Structure, Size, and Demographics
(American Society of Civil Engineers, 2007)Although the water sector (or water industry) is vital to the United States, national reporting systems do not include its economic or employment statistics. These would help policy makers and the public understand the ... -
Robust Least-Cost Design of Water Distribution Networks Using Redundancy and Integration-Based Methodologies
(American Society of Civil Engineers, 2007)Two approaches to solving the problem of robust least-cost design of water distribution systems under uncertainty in input parameters are considered. The first approach (redundant design) is based on redundancy in design, ... -
Ant Colony Optimization Applied to Water Distribution System Design: Comparative Study of Five Algorithms
(American Society of Civil Engineers, 2007)Water distribution systems (WDSs) are costly infrastructure, and much attention has been given to the application of optimization methods to minimize design costs. In previous studies, ant colony optimization (ACO) has ... -
