Impacts of Future Climate Conditions and Forecasted Population Growth on Water Supply Systems in the Puget Sound Region
(American Society of Civil Engineers, 2011)There is evidence that long-term climate change has altered streamflow patterns in the Puget Sound region, particularly during spring and summer months, and forecasts suggests these changes will continue. This research ... -
Efficient Hydraulic State Estimation Technique Using Reduced Models of Urban Water Networks
(American Society of Civil Engineers, 2011)This paper describes and demonstrates an efficient method for online hydraulic state estimation in urban water networks. The proposed method employs an online predictor-corrector (PC) procedure for forecasting future water ... -
Development of an Improved Approach for Selecting Storm-Water Best Management Practices
(American Society of Civil Engineers, 2011)This paper discusses the development of a software-aided approach to best management practice (BMP) selection. Supported with input from a geographic information system (GIS), this software provides an algorithmic, ... -
Pareto Optimality for Sensor Placements in a Water Distribution System
(American Society of Civil Engineers, 2011)As society looks to provide the most effective identification of possible intrusion events, issues of sensor placement in water distribution systems are drawing increased attention. A multiple objective optimization problem ... -
Evaluating Water Demands under Climate Change and Transitions in the Urban Environment
(American Society of Civil Engineers, 2011)Urban regions are complex and dynamic with many external and internal factors driving growth, movement, and composition. Forecasting regional characteristics important for long-term planning is inherently difficult for ... -
Stakeholder Consensus Building in Multiobjective Environments
(American Society of Civil Engineers, 2011)This paper introduces a method that assists in the evaluation of project and policy alternatives by identifying stakeholder reactions not only to the predicted economic, environmental, and social impacts but also to the ... -
Transient Modeling of a Full-Scale Distribution System: Comparison with Field Data
(American Society of Civil Engineers, 2011)The usefulness of transient models depends on their predictive ability. Consequently, their results should ideally be validated with field data. Despite numerous theoretical developments in the area of surge analysis, ... -
Object-Oriented Bayesian Networks for Participatory Water Management: Two Case Studies in Spain
(American Society of Civil Engineers, 2011)Object-oriented Bayesian networks (OOBNs) have recently been introduced to model water systems that can be represented as repetitive patterns. This paper shows the way in which OOBNs can be used as a groundwater management ... -
Optimal Multipurpose-Multireservoir Operation Model with Variable Productivity of Hydropower Plants
(American Society of Civil Engineers, 2011)Stochastic dual dynamic programming (SDDP) is one of the few methods available to solve multipurpose-multireservoir operation problems in a stochastic environment. This algorithm requires that the one-stage optimization ... -
Evaluating the Environmental Impacts of Water Distribution Systems by Using EIO-LCA-Based Multiobjective Optimization
(American Society of Civil Engineers, 2011)Climate change has made environmental impact a factor of growing importance in decision making for municipalities. Increasingly, the environmental impacts of expanding and operating a water distribution system (WDS) are ... -
Optimization of the Operation of Large-Scale Multisource Water-Supply Systems
(American Society of Civil Engineers, 2011)This paper describes a simulation-optimization model aimed at helping water utilities determine the best way to operate large-scale multisource water-supply systems. The operation of water systems is optimized taking into ... -
Comparative Evaluation of Drought Indexes: Case Study on the Yarra River Catchment in Australia
(American Society of Civil Engineers, 2011)Drought indexes (DIs) have commonly been used to quantify drought conditions around the world. Most DIs are developed for specific regions and, therefore, may not be directly applicable to other regions because of the ... -
Dynamic Programming Methodology for Prioritizing Sewerage Projects
(American Society of Civil Engineers, 2011)A simple yet effective approach is developed on the basis of dynamic programming (DP) as a means of objectively selecting and prioritizing sewerage projects within available funds and system capacity. The methodology ... -
Price Sensitivity of Farmer Preferences for Irrigation Water–Pricing Method: Evidence from a Choice Model Analysis in Krishna River Basin, India
(American Society of Civil Engineers, 2011)Water pricing is one of the water-demand management tools advocated to improve water allocation, water-use efficiency, equity, and sustainability. Often, however, little attention is paid to farmers’ cooperation, which is ... -
Contamination Source Identification in Water Distribution Systems Using an Adaptive Dynamic Optimization Procedure
(American Society of Civil Engineers, 2011)Contamination source identification involves the characterization of the contaminant source based on observations that stream from a set of sensors in a water distribution system (WDS). The streaming data can be processed ... -
Applying Dynamic Surrogate Models in Noisy Genetic Algorithms to Optimize Groundwater Remediation Designs
(American Society of Civil Engineers, 2011)Computational cost is a critical issue for large-scale water-resource optimization under uncertainty, since time-intensive Monte Carlo simulations are often required to evaluate over multiple parameter realizations. This ... -
Risk Explicit Interval Linear Programming Model for Uncertainty-Based Nutrient-Reduction Optimization for the Lake Qionghai Watershed
(American Society of Civil Engineers, 2011)Water quality management is subject to large uncertainties due to inherent randomness in the natural system and vagueness in the decision-making process. For water quality management optimization models, this means that ... -
