Multiobjective Optimization for Least Cost Design and Resiliency of Water Distribution Systems
(American Society of Civil Engineers, 2014)The multiobjective optimization model described in this study is aimed at exploring the tradeoff between cost and resiliency for water distribution systems optimal design. Many have dealt previously with minimizing cost ... -
Burst Detection Using an Artificial Immune Network in Water-Distribution Systems
(American Society of Civil Engineers, 2014)A new method using artificial immune network is presented to identify pipe burst in water-distribution systems. Burst detection is considered as the problem of pattern recognition in the proposed method. An artificial ... -
Robustness of Designs for Drinking Water Contamination Warning Systems under Uncertain Conditions
(American Society of Civil Engineers, 2014)Contamination warning systems (CWSs) for drinking water distribution systems (WDSs) are used to reduce the potential adverse effects of intentional or accidental WDS contamination. They are designed on the basis of possible ... -
Event-Based Approach to Optimize the Timing of Water Main Rehabilitation with Asset Management Strategies
(American Society of Civil Engineers, 2014)Municipalities with limited budgets will have to rehabilitate their stock of deteriorated water mains in the coming decades. Optimization and asset management offer municipalities the opportunity to plan the rehabilitation ... -
Study of Burst Alarming and Data Sampling Frequency in Water Distribution Networks
(American Society of Civil Engineers, 2014)In recent research, the residual of the Kalman filter applied to flow measurements in water distribution systems has been found to strongly correlate with bursts. A positive residual represents an unexpected extra flow, ... -
Efficient Identification of Segments in Water Distribution Networks
(American Society of Civil Engineers, 2014)A valve-enclosed segment is the basic unit of water distribution networks (WDNs) in reliability analysis and optimal design. Based on the theory of the transitive closure of graphs, this paper presents a new method for ... -
Stochastic Programming for Improved Multiuse Reservoir Operation in Burkina Faso, West Africa
(American Society of Civil Engineers, 2015)A network of reservoirs and diversion structures in the Comoé River Basin in southwestern Burkina Faso, West Africa, provides municipal water supply and irrigation for sugarcane agribusiness and downstream farmers. The ... -
Application of a Combination Model Based on Wavelet Transform and KPLS-ARMA for Urban Annual Water Demand Forecasting
(American Society of Civil Engineers, 2014)A combination of models including wavelet transform and kernel partial least squares-autoregressive moving average (KPLS-ARMA) is proposed to explore the nonstationarity of the urban annual water demand series, the nonlinear ... -
Evolution of a Watershed-Management Framework in the Kentucky River Basin
(American Society of Civil Engineers, 2014)Following an increased emphasis on watershed management by the U.S. Environmental Protection Agency (EPA) in the 1990s, the Kentucky Division of Water (KDOW) developed and implemented a watershed-management framework process ... -
Reservoir Management Optimization for Basin-Wide Ecological Restoration in the Connecticut River
(American Society of Civil Engineers, 2014)Evidence from ecological studies suggests that the alteration of river flows downstream of reservoirs can threaten native aquatic ecosystems and the services they offer. Innovative revisions to water management practices ... -
Cost-Benefit Analysis for Hydropower Production in Water Distribution Networks by a Pump as Turbine
(American Society of Civil Engineers, 2014)The use of microhydroelectric plants in urban pipe networks, based on the combination of a pump as turbine (PAT), two regulating valves, and two pressure meters, is proposed along with simple automation rules. Its economic ... -
Modeling and Field Work to Investigate the Relationship between Age and Quality of Tap Water
(American Society of Civil Engineers, 2014)It has been widely theorized that water age may be a useful indicator of the quality of water within drinking water distribution networks. However, there is limited evidence of model simulation results being related to ... -
Inexact Fuzzy Chance-Constrained Nonlinear Programming Approach for Crop Water Allocation under Precipitation Variation and Sustainable Development
(American Society of Civil Engineers, 2014)In this study, an inexact fuzzy chance-constrained nonlinear programming (IFCCNP) method was developed for agriculture water resources management under multiple uncertainties. It improved upon the previous stochastic ... -
Operating Rules for an Off-Stream Blending Reservoir to Control Nitrate in a Municipal Water System
(American Society of Civil Engineers, 2014)Municipal water supply systems dependent on surface water sources that are susceptible to both low flows and contamination can use off-stream blending reservoirs (OSBR) both to increase their yield and avoid investments ... -
Evaluating the Performance of Urban Water Utilities: Robust Nonparametric Approach
(American Society of Civil Engineers, 2014)This paper empirically analyzes the efficiency of urban water utilities using state-of-the-art methodology combining data envelopment analysis (DEA) and a two-stage double bootstrap procedure. In the first stage, robust ... -
On the Use of System Performance Metrics for Assessing the Value of Incremental Water-Use Permits
(American Society of Civil Engineers, 2014)A novel approach on quantifying the value of an incremental surface water–use permit in an integrated water resources system consisting of groundwater, surface water, off-stream reservoir, and desalinated seawater sources ... -
Performance-Based Evaluation of an Improved Robust Optimization Formulation
(American Society of Civil Engineers, 2014)Much progress has been made in the standardization of uncertainty analysis techniques for simulation modeling but less progress has been made in optimization modeling. Among the various techniques used for optimization ... -
Floodway System Operation along Levee-Protected Rivers
