Flood Storage Allocation Rules for Parallel Reservoirs
(American Society of Civil Engineers, 2015)Optimal operating policies have been derived for reservoirs in series and in parallel for various purposes, but little formal analysis has been done for flood operation of parallel reservoirs. For flood management, parallel ... -
Optimal Upgrading of Water Distribution Network Redundancy
(American Society of Civil Engineers, 2015)A new two-stage iterative methodology is presented for upgrading of single-source water distribution networks to achieve redundancy. In the first stage, the existing network is strengthened using linear programming (LP) ... -
Influence of Network Model Detail on Estimated Health Effects of Drinking Water Contamination Events
(American Society of Civil Engineers, 2015)Network model detail can influence the accuracy of results from analyses of water distribution systems. Previous work has shown the limitations of skeletonized network models when considering water quality and hydraulic ... -
Vulnerability Assessment of Water Distribution Networks under Seismic Actions
(American Society of Civil Engineers, 2015)A methodology to analyze the vulnerability of water distribution networks (WDNs) to earthquakes by means of risk assessment is presented. The consequences of multiple pipe failures due to earthquakes are investigated in ... -
Development and Application of the Bat Algorithm for Optimizing the Operation of Reservoir Systems
(American Society of Civil Engineers, 2015)Optimal utilization of water resources by means of water transfers and reservoirs in semiarid and arid regions is used to mitigate natural water scarcity. In this context, metaheuristic algorithms for optimum reservoir ... -
Discussion of “<i>Optimal Upgrading of Hydraulic‐Network Reliability</i>” by Lindell Ormsbee and Avner Kessler (November/December, 1990, Vol. 116, No. 6)

Real-Time Guidance for Hydrant Flushing Using Sensor-Hydrant Decision Trees
(American Society of Civil Engineers, 2015)A utility may detect contaminant in a water distribution network through water quality sensor information, which indicates that a biological pathogen or chemical contaminant is present in the network. A utility manager ... -
Developing Key Indicators for Adaptive Water Planning
(American Society of Civil Engineers, 2015)With hard-to-predict changes in future demand, climate, supply options, technological opportunities, and budgetary constraints, water agency plans should be flexible and robust, designed to meet agency goals over a wide ... -
Optimization Research of Parallel Pump System for Improving Energy Efficiency
(American Society of Civil Engineers, 2015)In applications where demand on a water supply system changes frequently and widely, the operating conditions of pumps always deviate from the design conditions, and this error leads to poor efficiency and reliability. For ... -
Quarter-Hourly Operation of Large-Scale Hydropower Reservoir Systems with Prioritized Constraints
(American Society of Civil Engineers, 2015)This paper deals with the optimization of short-term hydropower scheduling when a mathematically feasible solution cannot be achieved. Generally, the numerical search procedure terminates with the detection of infeasibility ... -
Energy Assessment of Pressurized Water Systems
(American Society of Civil Engineers, 2015)This paper presents three new indicators for assessing the energy efficiency of a pressurized water system and the potential energy savings relative to the available technology and economic framework. The first two indicators ... -
Using Real Options in the Optimal Design of Water Distribution Networks
(American Society of Civil Engineers, 2015)Water supply systems have to satisfy water needs in terms of quantity and quality. The constant changes in urban areas require the regular adaptation of the water supply infrastructure to meet new circumstances. However, ... -
