Marginal Cost of Reducing Unplanned Water Supply Interruptions: Influence of Water Company Ownership
(ASCE, 3/1/2021)Water companies are expected to deliver high-quality water services to their customers that include, among others, continuity of water supply. Unplanned water supply interruptions (UWSI) indicate a cost for the water ... -
Isolation Valve Impact on Failure Severity and Risk Analysis
(ASCE, 3/1/2021)The number of isolation valves installed in a water distribution pipe network is typically based on conservative rules of thumb that have been propagated throughout the water industry. However, little work has been done ... -
Transient Response Analysis of Branched Pipe Systems toward a Reliable Skeletonization
(ASCE, 2/1/2021)In this paper, the transient behavior of a single-branch pipe system (Y-system) is analyzed by means of numerical experiments in which a wide range of branch characteristics (i.e., size, location, and operating ... -
Spatial Equality and Equity for Effective Emergency Water Distribution System: Points of Distribution
(ASCE, 3/1/2021)In recent years, there have been multiple incidents of drinking water contamination reported in major US cities. A critical part of the response to such an emergency is the distribution of bottled water to affected residents ... -
Evaluating Potential Impact of Short-Term Augmentation of Groundwater Production on Groundwater Levels in Tampa Bay Region
(ASCE, 2/1/2021)Water supply management is challenging due to diverse stakeholders, conflicting objectives, increasing water demand, increasing regulation complexity, changing climate, and infrastructure constraints. To manage residual ... -
Urban Water Demand Modeling Using Machine Learning Techniques: Case Study of Fortaleza, Brazil
(ASCE, 1/1/2021)Despite recent efforts to apply machine learning (ML) for water demand modeling, overcoming the black-box nature of these techniques to extract practical information remains a challenge, especially in developing countries. ... -
Merging Fluid Transient Waves and Artificial Neural Networks for Burst Detection and Identification in Pipelines
(ASCE, 1/1/2021)The occurrence of bursts in water pipelines can not only prevent the system from functioning properly, but it can also produce significant water loss that disrupts activities in urban areas. Therefore, the detection and ... -
Hybrid Models for Water Demand Forecasting
(ASCE, 2/1/2021)An accurate prediction of future water consumption is necessary to create a satisfactory design for a water distribution system. In this study, two new hybrid approaches are proposed for accurately predicting future hourly ... -
Development of a Tool for Measuring Resilience of Water Supply Systems in Tanzania: Technical Dimension
(ASCE, 2/1/2021)Tanzania water supply systems (WSSs) are facing resilience problems, compromising the quality and coverage of water supply services during floods. The expected rise in flood frequency and magnitude due to climate change ... -
Cyclic Feedback Updating Approach and Uncertainty Analysis for the Source Identification of DNAPL-Contaminated Aquifers
(ASCE, 2/1/2021)Hypothetical and real case studies were combined to explore the feasibility and effectiveness of a surrogate-based cyclic feedback updating approach for groundwater contamination source identification (GCSI) at dense ... -
Impact of Climate Change on Hydrology and Hydrologic Extremes of Upper Blue Nile River Basin
(ASCE, 2/1/2021)The potential global warming impact on the extreme and mean streamflow of the Upper Blue Nile (UBN) River Basin was projected for the 2050s and 2080s by three hydrological models [Nedbør-Afstrømnings Model (NAM), Variable ... -
Leakage Detection in Water Distribution Systems Based on Time–Frequency Convolutional Neural Network
(ASCE, 2/1/2021)Effectively detecting leaks is critical to improving leakage control management. Acoustic detection is one of the main leakage detection methods, and has been widely used in water utilities. Nevertheless, the effectiveness ... -
Urban Water Demand: Statistical Optimization Approach to Modeling Daily Demand
(ASCE, 2/1/2021)Reliable forecasts of water demand that account for factors that drive demand are imperative to understanding future urban water needs. The effects of meteorological dynamics and sociocultural settings are expressed weakly ... -
Setting Future Water Rates for Sustainability of a Water Distribution System
(ASCE, 2/1/2021)This study introduces an approach to plan future water rates to achieve water distribution system (WDS) sustainability triple-top line (TTL) targets. The WDS components are modeled by connecting the EPANET hydraulic model ... -
Stochastic Optimization of Reservoir Operation by Applying Hedging Rules
(ASCE, 2/1/2021)The high percentage of reliability of water resources systems has always been considered as a positive advantage by users. However, in arid and semiarid areas in which the flow rate of the reservoir is highly variable, it ... -
Interval Analysis of the Loss of Life Caused by Dam Failure
(ASCE, 1/1/2021)Both hydrodynamic factors and social factors have large impacts on the loss of life caused by dam failure. Relatively large uncertainty intervals of the influencing factors lead to changes in the potential loss of life. ... -
Design of Integrated Water Systems: Water Distribution System, Household Water-Saving Scheme, and Sanitary Sewer Perspectives
(ASCE, 2/1/2021)An integrated design method that complements the increasing uptake of water-saving schemes (WSSs) is presented. WSSs may consist of water-saving fittings, appliances, rainwater-harvesting systems (RWHSs), and water-reuse ... -
Source Contamination Detection Using Novel Search Space Reduction Coupled with Optimization Technique
