Optimizing Hydropower Reservoirs Operation via an Orthogonal Progressive Optimality Algorithm
(American Society of Civil Engineers, 2018)The progressive optimality algorithm (POA) is commonly used to identify optimal hydropower operation schedules in China. However, POA may not converge within a reasonable time for large and complex problems because its ... -
Fractal Singularity–Based Multiobjective Monitoring Networks for Reactive Species Contaminant Source Characterization
(American Society of Civil Engineers, 2018)The first step in effective design of contaminated aquifer site remediation is the accurate characterization of contaminant sources, which requires a large amount of concentration measurement data. However, in real-world ... -
Reducing Combined Sewer Overflows through Model Predictive Control and Capital Investment
(American Society of Civil Engineers, 2018)Operational strategies to mitigate combined sewer overflows (CSOs) in older urban areas may be enhanced through real-time decision support provided to sewer operators. During severe rainfall events, real-time hydraulic ... -
Decreasing the Discoloration Risk of Drinking Water Distribution Systems through Optimized Topological Changes and Optimal Flow Velocity Control
(American Society of Civil Engineers, 2018)In this paper, a new mathematical framework is proposed for maximizing the self-cleaning capacity (SCC) of drinking water distribution systems by controlling the diurnal peak flow velocities in the pipes under normal ... -
Untitled
(American Society of Civil Engineers, 2018)Two implementations of the Pareto archived dynamically dimensioned search (PADDS) algorithm using different selection metrics are applied to 12 water distribution network (WDN) design benchmark problems from the literature. ... -
Using Joint Probability Distribution of Reliability and Vulnerability to Develop a Water System Performance Index
(American Society of Civil Engineers, 2018)Assessing the long-term reliability and vulnerability of municipal water supply systems often employs system modeling to analyze performance. Generally, decision-makers have long been in search of a metric that presents a ... -
Energy Metrics to Evaluate the Energy Use and Performance of Water Main Assets
(American Society of Civil Engineers, 2018)Managing aging infrastructure has become one of the greatest challenges for water utilities, particularly when faced with selecting the most critical pipes for rehabilitation from among the thousands of candidates. This ... -
Leakage Control and Energy Recovery Using Variable Speed Pumps as Turbines
(American Society of Civil Engineers, 2018)One of the primary concerns in water supply systems is pressure control. High pressure increases both leakage and the risk of pipes bursting, while low pressure can reduce the water supplied to consumers and allow the ... -
Centralized and Decentralized Strategies for Dual Water Supply: Case Study
(American Society of Civil Engineers, 2018)Dual water systems are becoming an important urban water management strategy as more utilities adopt increasingly integrated approaches that enable matching source water quality to the intended use, more efficient use of ... -
Pipe Material Effect on Water Network Leak Detection Using a Pressure Residual Vector Method
(American Society of Civil Engineers, 2018)Municipal authorities face many challenges in maintaining an effective water distribution service (WDS) because of aging infrastructure and financial limitations. Effective leak detection methods minimize the cost of pipe ... -
Multipurpose Design of the Flow-Control System of a Steep Water Main
(American Society of Civil Engineers, 2018)This work presents the technical characteristics and the regulation system of a complex water supply system (WSS) in an Italian Alpine valley. The WSS faced multiple challenges: water supply over a large area, hydropower ... -

Comparing Model-Based and Model-Free Streamflow Simulation Approaches to Improve Hydropower Reservoir Operations
(American Society of Civil Engineers, 2018)This paper presents a comparison between an inflow model-based and an inflow model-free optimization method applied to a hydropower system. Widely used stochastic dynamic programming (SDP) and the evolutionary multiobjective ... -
Performance and Cost Analysis of Decentralized Wastewater Treatment Plants in Northern India: Case Study
(American Society of Civil Engineers, 2018)In this study, a techno-economic analysis of 16 decentralized wastewater treatment plants (WWTPs) based on various technologies was performed in northern India. Six elements including treatment performance, land use, capital ... -
Extensive-Form Game for Examining Mutual Trust between a Reservoir Operator and Agricultural Water Users
(American Society of Civil Engineers, 2018)This paper aims to illustrate the hidden bargain decision-making process undertaken by a reservoir operator and basin farmers along with water allocation of the Al-Tharthar reservoir located on the Tigris river. The amount ... -
Understanding Water Utility Attitudes toward Water Transfers and Risk: Pretest Results
(American Society of Civil Engineers, 2018)Water transfers between utilities can be a cost-effective substitute for supply infrastructure expansions when seeking to reduce vulnerability to drought. Water utility employees may choose not to use water transfers, ... -
