Correction of the <i>EPANET</i> Inaccuracy in Computing the Efficiency of Variable Speed Pumps
(American Society of Civil Engineers, 2013)One attractive possibility for saving energy in water distribution systems is the introduction of variable speed pumps (VSPs). However, to assess the cost effectiveness of using VSPs, a correct estimate of VSP energy ... -
Integrated Approach to Water Allocation in River Basins
(American Society of Civil Engineers, 2013)Available water resources are decreasing in river basins around the world. Some reseachers have suggested various indicators and methods that should be used to allocate water resources. This paper attempts an integrated ... -
Optimal Tank Design in Water Distribution Networks: Review of Literature and Perspectives
(American Society of Civil Engineers, 2014)Water distribution networks (WDN) are traditionally designed without integrating tanks in the optimization process, despite the numerous benefits tanks bring to network operation. Since 2004, a number of efforts have been ... -
General Multiobjective Model and Simulated Annealing Algorithm for Waste-Load Allocation
(American Society of Civil Engineers, 2013)Waste-load allocation (WLA) is a difficult problem with multiobjective features, which requires models that consider a full range of competing goals to identify good and practical solutions. In this study, a general and ... -
Efficiency Curves for Hydroelectric Generating Units
(American Society of Civil Engineers, 2014)This paper presents a methodology for obtaining and adjusting of efficiency curves for hydroelectric generating units. It is based on measured data of power, gross head, and water discharge recorded by the company that ... -
Value of Information in the Design of Resilient Water Distribution Sensor Networks
(American Society of Civil Engineers, 2013)The ability to monitor the flow and how water transforms throughout water networks would greatly improve the management of those distribution systems. The sensor placement problem attempts to find the locations of monitoring ... -
Dynamic Framework for Intelligent Control of River Flooding: Case Study
(American Society of Civil Engineers, 2014)This paper presents a case study on the application of a dynamic framework for the intelligent control of flooding in the Boise River system in Idaho. This framework couples a robust and numerically efficient hydraulic ... -
Parambikulam-Aliyar Project Operations Optimization with Reliability Constraints
(American Society of Civil Engineers, 2013)In this paper, a recently developed stochastic programming technique that includes reliability constraints is used to solve the operations optimization problem of the Parambikulam-Aliyar project (PAP), a multireservoir ... -
Developing an Agricultural Planning Model in a Watershed Considering Climate Change Impacts
(American Society of Civil Engineers, 2013)Societies are facing major challenges in allocating water resources to growing water demands due to population growth and industrial and agricultural developments. With increasing water scarcity, the need to increase ... -
Design of Efficient Water Pricing Policies Integrating Basinwide Resource Opportunity Costs
(American Society of Civil Engineers, 2013)By ignoring the opportunity cost of water use, water is undervalued, which can lead to significant errors in investments and water allocation decisions. The marginal resource opportunity cost (MROC) varies in time and ... -
Probabilistic Analysis and Optimization to Characterize Critical Water Distribution System Contamination Scenarios
(American Society of Civil Engineers, 2013)Characterization of critical water distribution system (WDS) contamination scenarios—defined by a set of attributes, a probability of occurrence, and a specific level of consequences—is a prerequisite for preparation of ... -
Design-Variable Optimization of Hydropower Tunnels and Surge Tanks Using a Genetic Algorithm
(American Society of Civil Engineers, 2013)Optimal design of tunnels and surge tanks is a major concern in the implementation and operation of large hydropower plants, particularly those in which tunnels are long and water hammer is likely. In this paper, flow ... -
Reservoir Operation for Simultaneously Meeting Water Demand and Sediment Flushing: Stochastic Dynamic Programming Approach with Two Uncertainties
(American Society of Civil Engineers, 2013)River bed materials are commonly removed and conveyed downstream. In this process, some sediments are deposited in reservoirs, causing a decrease in reservoir active storage capacity and thus its ability to meet water ... -
Methods and Tools for Managing Losses in Water Distribution Systems
(American Society of Civil Engineers, 2013)The water industry worldwide is facing challenges of water and revenue losses. To reduce these losses and improve efficiency of water distribution systems, tools and methods have been developed over the years. This paper ... -
Bilevel Optimization of Regional Water Resources Allocation Problem under Fuzzy Random Environment
