Topological Placement of Quality Sensors in Water-Distribution Networks without the Recourse to Hydraulic Modeling
(ASCE, 2020)The detection of contaminant intrusion into a water-distribution network (WDN) is a difficult issue due to uncertainty related to the type of injected contaminant, source location, and intrusion time. The placement of water ... -
Multicriteria Decision-Making Model of Reservoir Operation Considering Balanced Applicability in Past and Future: Application to the Three Gorges Reservoir
(ASCE, 2020)Motivated by the emerging need for long-term and sustainable reservoir management, this paper developed a multicriteria decision-making (MCDM) model of reservoir operation with consideration of balanced applicability in ... -
Probability of Water Fixture Use during Peak Hour in Residential Buildings
(ASCE, 2020)The standard method for estimating instantaneous peak water use in premise plumbing systems (PPSs) is Hunter’s (1940) design curve, showing water demand versus fixture units. In recent years, federal regulations have ... -
Linear Model and Regularization for Transient Wave–Based Pipeline-Condition Assessment
(ASCE, 2020)Condition assessment or defect detection of a pipeline is a difficult inverse problem. This paper proposes a general linear model framework that can approximately describe a wide range of pipeline condition assessment and ... -
Resolving Emerging Issues with Aging Dams under Climate Change Projections
(ASCE, 2020)Concerns about the collapse of dams due to overtopping are increasing owing to heavy rainfall and frequent typhoons associated with climate change. As a result, there has been a spike in anxiety among residents living near ... -
Energy Recovery and Leakage-Reduction Optimization of Water Distribution Systems Using Hydro Turbines
(ASCE, 2020)Potential for energy recovery exists at any point within a water distribution system where the mechanical energy of excess water pressure can be converted into electrical energy. Energy conversion decreases the average ... -
