Accounting for Phasing of Construction within the Design of Water Distribution Networks
(American Society of Civil Engineers, 2014)The traditional optimization approach for water distribution mains is that of considering a single design scenario with prefixed nodal demands representing the peak values at the end of the life cycle of the construction. ... -
Simulation Study to Evaluate Temporal Aggregation and Variability of Stochastic Water Demands on Distribution System Hydraulics and Transport
(American Society of Civil Engineers, 2014)As utilities move toward more detailed hydraulic and water quality network models, the potential for the stochastic nature of consumptive demands having an effect on transport characteristics increases. A nonhomogeneous ... -
Evolutionary Algorithm and Expectation Maximization Strategies for Improved Detection of Pipe Bursts and Other Events in Water Distribution Systems
(American Society of Civil Engineers, 2014)A fully automated data-driven methodology for the detection of pipe bursts and other events that induce similar abnormal pressure/flow variations (e.g., unauthorized consumptions) at the district metered area (DMA) level ... -

Planning the Optimal Operation of a Multioutlet Water Reservoir with Water Quality and Quantity Targets
(American Society of Civil Engineers, 2014)The integration of quality and quantity issues in the management of water resources systems is key to meet society’s long-term needs for freshwater while maintaining essential ecological services and economic benefits. ... -
Reliability Assessment for Water Supply Systems under Uncertainties
(American Society of Civil Engineers, 2014)Reliability assessment of water supply systems (WSSs) is an important aspect of WSS planning and operations. Traditionally, WSS reliability involves the comparison of hydraulics (e.g., pressure or available water volume) ... -
Research Database of Water Distribution System Models
(American Society of Civil Engineers, 2014)Since the 1960s, researchers have continued to develop new methodologies and algorithms in support of the planning, design, and management of water distribution systems. While initial research focused on modeling the ... -
Noncrossover Dither Creeping Mutation-Based Genetic Algorithm for Pipe Network Optimization
(American Society of Civil Engineers, 2014)A noncrossover dither creeping mutation-based genetic algorithm (CMBGA) for pipe network optimization has been developed and is analyzed in this paper. This CMBGA differs from the classic genetic algorithm (GA) optimization ... -
Adsorption Model for Arsenate Transport in Corroded Iron Pipes with Application to a Simulated Intrusion in a Water Distribution Network
(American Society of Civil Engineers, 2014)Adsorption to pipe wall materials significantly affects the fate and transport of certain contaminants in water distribution systems. For example, arsenate has a strong affinity for iron oxide, a substance common in water ... -
Predicting the Timing of Water Main Failure Using Artificial Neural Networks
(American Society of Civil Engineers, 2014)Effective management of aging water distribution infrastructure is essential for preserving the economic vitality of North American municipalities. Historical failures within Scarborough, Ontario, Canada, reveal a seasonal ... -
Modeling Contaminant Spills in the Truckee River in the Western United States
(American Society of Civil Engineers, 2014)Originating at Lake Tahoe, the Truckee River provides 85% of drinking water for the Reno/Sparks metropolitan area. Major highways and a railroad run adjacent to the river, which increases risk of a contaminant spill into ... -
Automated Detection of Pipe Bursts and Other Events in Water Distribution Systems
(American Society of Civil Engineers, 2014)This paper presents a new methodology for the automated near-real-time detection of pipe bursts and other events that induce similar abnormal pressure/flow variations (e.g., unauthorized consumptions) at the district metered ... -
Heterogeneous Residential Water and Energy Linkages and Implications for Conservation and Management
(American Society of Civil Engineers, 2014)This paper develops an integrated approach to model heterogeneous household water and energy use and their linkages. The approach considers variations in behavioral and technological water and energy use factors that affect ... -
Optimal Real-Time Operation of Multipurpose Urban Reservoirs: Case Study in Singapore
(American Society of Civil Engineers, 2014)The sustainable urban water management paradigm is based on the idea that water supply, storm water drainage, and wastewater disposal are interrelated resources that can increase the sustainability at the urban scale. In ... -
