Texas Water Availability Modeling System
(American Society of Civil Engineers, 2005)A water availability modeling system was implemented during 1997–2004 by the Texas Commission on Environmental Quality and its contractors, in collaboration with the water management community, under a mandate provided by ... -
Daily Operation of Reservoir Subject to Yearly Probabilistic Constraints
(American Society of Civil Engineers, 2005)This paper addresses the problem of determining the optimal daily operating policy of a small reservoir subject to yearly probabilistic constraints on floods and shortages. The problem is difficult to solve because the ... -
Intensive Groundwater Use: Silent Revolution and Potential Source of Social Conflicts
(American Society of Civil Engineers, 2005) -
Which Groundwater Remediation Objective is Better: A Realistic One or a Simple One?
(American Society of Civil Engineers, 2005)One of the first steps in developing an optimal water resources design model is creating appropriate objective functions that represent the primary goals of the design. In many cases, one major objective is minimizing cost. ... -
Characterizing the Severity and Risk of Drought in the Poudre River, Colorado
(American Society of Civil Engineers, 2005)The implementation of water use restrictions in a given district is very much related to the severity of an evolving drought; thus, water management agencies such as City Water Departments often face the question of how ... -
Optimization of Integrated Urban Wet-Weather Control Strategies
(American Society of Civil Engineers, 2005)An optimization method for urban wet-weather control (WWC) strategies is presented. The developed optimization model can be used to determine the most cost-effective strategies for the combination of centralized storage-release ... -
Water Distribution System Optimization Using Metamodels
(American Society of Civil Engineers, 2005)Genetic algorithms (GAs) have been shown to apply well to optimizing the design and operations of water distribution systems (WDSs). The objective has usually been to minimize cost, subject to hydraulic constraints such ... -
Sensor Placement in Municipal Water Networks
(American Society of Civil Engineers, 2005)We present a model for optimizing the placement of sensors in municipal water networks to detect maliciously injected contaminants. An optimal sensor configuration minimizes the expected fraction of the population at risk. ... -
Treatment and Distribution System Effects on Chloramine Decay, pH, Nitrification, and Disinfection By-Products: Case Study1
(American Society of Civil Engineers, 2005)The Massachusetts Water Resources Authority (MWRA) supplies wholesale unfiltered surface water to 2.2 million people in 43 communities, including Boston. Current MWRA treatment consists of adding hypochlorite for primary ... -
Simulating Exposures to Deliberate Intrusions into Water Distribution Systems
(American Society of Civil Engineers, 2005)A well-known network solver (EPANET) and a novel water-use generator (PRPsym) were linked in Monte Carlo computer experiments to simulate a deliberate biochemical assault on a municipal drinking-water distribution system. ... -
Trade-off between Total Cost and Reliability for Anytown Water Distribution Network
(American Society of Civil Engineers, 2005)This paper investigates the application of multiobjective evolutionary algorithms to the identification of the payoff characteristic between total cost and reliability of a water distribution system using the well-known ... -
Geographic Information System-based Pipeline Route Selection Process
(American Society of Civil Engineers, 2005)The Metropolitan Water District of Salt Lake and Sandy recently began construction of the Point of the Mountain Aqueduct. This 1,524 mm (60 in.) diameter pipeline will convey finished water approximately 9 km ( -
Optimal Water Allocation for the Transboundary Subernarekha River, India
(American Society of Civil Engineers, 2005)This paper presents a linear programming model for optimal water allocations in a large river basin system. The model is applied to the transboundary Subernarekha River in India, which has two main stream reservoirs, two ... -
Detection and Location of a Partial Blockage in a Pipeline Using Damping of Fluid Transients
(American Society of Civil Engineers, 2005)The effects of a partial blockage on pipeline transients are investigated analytically. A partial blockage is simulated using an orifice equation, and the influence of the blockage on the unsteady pipe flow is considered ... -

Self-Adaptive Penalty Approach Compared with Other Constraint-Handling Techniques for Pipeline Optimization
(American Society of Civil Engineers, 2005)Optimal design and rehabilitation of a water distribution system is a constrained nonlinear optimization problem. A penalty function is often employed to transform a constrained into a nonconstrained optimization problem ... -
Characterizing Pipe Wall Demand: Implications for Water Quality Modeling
(American Society of Civil Engineers, 2005)It has become generally accepted that water quality can deteriorate in a distribution system through reactions in the bulk phase and at the pipe wall. These reactions may be physical, chemical, or microbiological in nature. ... -
Threat Assessment of Water Supply Systems Using Markov Latent Effects Modeling
(American Society of Civil Engineers, 2005)Recent amendments to the Safe Drinking Water Act emphasize efforts toward safeguarding our nation’s water supplies against attack and contamination. Specifically, the Public Health Security and Bioterrorism Preparedness ... -
Effects of Discharge Permit Trading on Water Quality Reliability
(American Society of Civil Engineers, 2005)Transferable discharge permit (TDP) programs show potential as cost-effective methods of pollution control. Nevertheless, there remain uncertainties that, if not adequately addressed, might impair their success. Concerns ...
