Regional Wastewater System Planning under Population Dynamics Uncertainty
(American Society of Civil Engineers, 2014)Regional wastewater systems are used for the collection and treatment of the wastewater generated in a region and aimed at guaranteeing surface water quality. The volumes of wastewater to process depend on future population ... -
Economic Value of Storage in Multireservoir Systems
(American Society of Civil Engineers, 2014)Following three decades of rather low investment in dams, many regions throughout the world are now seeking to further develop new storage capacity to meet exploding demands for water and to hedge against the risk posed ... -
Forest-Core Partitioning Algorithm for Speeding Up Analysis of Water Distribution Systems
(American Society of Civil Engineers, 2014)Commonly, water distribution networks have many treed or branched subgraphs. The equations for these systems are often solved for the steady-state flows and heads with a fast implementation of Newton’s method such as the ... -
Simulation-Based Inexact Two-Stage Chance-Constraint Quadratic Programming for Sustainable Water Quality Management under Dual Uncertainties
(American Society of Civil Engineers, 2014)Water quality planning is complicated itself but further challenged by the existence of uncertainties and nonlinearities in terms of model formulation and solution. In this study, a simulation-based inexact two-stage ... -
Application of Multimodal Optimization for Uncertainty Estimation of Computationally Expensive Hydrologic Models
(American Society of Civil Engineers, 2014)The generalized likelihood uncertainty estimation (GLUE) framework has been widely used in hydrologic studies. However, the extensive random sampling causes a high computational burden that prohibits the efficient application ... -
Integrated Water Management for Environmental Flows in the Rio Grande
(American Society of Civil Engineers, 2014)In the Rio Grande transboundary basin, environmental flows have not been considered as an integral part of the water management. This research focuses on the Big Bend, a reach located along the Rio Grande mainstem. Important ... -
Technology Adoption for Long-Term Drought Resilience
(American Society of Civil Engineers, 2014)In this paper, a mathematical model of optimal management of prolonged and consecutive drought events is developed to evaluate circumstances under which the adoption of a water-efficient technology may offer long-term ... -
Optimal Water Distribution Network Design Accounting for Valve Shutdowns
(American Society of Civil Engineers, 2014)The hydraulic system functioning is determined by the boundary conditions (e.g., network topology, pipe resistances/diameters, tank levels, status of control devices, and status of pumps). Shutdown of isolation valves to ... -
Methodology for Comparing Evolutionary Algorithms for Optimization of Water Distribution Systems
(American Society of Civil Engineers, 2014)In recent years, a number of evolutionary algorithms have been proposed for optimizing the design and operation of water distribution systems (WDSs). These evolutionary algorithms include genetic algorithms, ant colony ... -
Water as Warning Medium: Food-Grade Dye Injection for Drinking Water Contamination Emergency Response
(American Society of Civil Engineers, 2014)Once contamination of a drinking water distribution system is suspected or known, emergency managers may take different actions in response to the perceived state of the system. This study explores performance of a novel ... -
Improving Efficiency of the Bayesian Approach to Water Distribution Contaminant Source Characterization with Support Vector Regression
(American Society of Civil Engineers, 2014)There are multiple sources of uncertainties in urban water-distribution systems, e.g., nodal water demand and sensor measurement error. All of these uncertainties increase the complexity of contaminant source identification ... -
Bargaining Models for Optimal Design of Water Distribution Networks
(American Society of Civil Engineers, 2014)Optimal design of water distribution networks (WDN) involves an evaluation of both consumers’ pressure benefits and investors’ economic objectives. The aforementioned objectives often conflict, so finding the optimal ... -
Dealing with Uncertainty in Water Distribution System Models: A Framework for Real-Time Modeling and Data Assimilation
(American Society of Civil Engineers, 2014)Water distribution system (WDS) models may improve system control when applied using real-time data, and in doing so, help meet consumer and regulatory demands. Such real-time modeling often overlooks the multiple sources ... -
Effects of Climate Change on the Surface-Water Management of the South Saskatchewan River Basin

Operating Water Distribution Networks during Water Shortage Conditions Using Hedging and Intermittent Water Supply Concepts
(American Society of Civil Engineers, 2013)Population increase and requirements as well as water resource limitations reveal the necessity for the optimal operation of water distribution networks (WDNs), especially during shortage events. Because WDNs directly ... -
Optimal Location of Sediment-Trapping Best Management Practices for Nonpoint Source Load Management
(American Society of Civil Engineers, 2013)Selecting approaches to managing nonpoint source pollution is challenging due to the complex generation and transport processes that influence the quantity of pollutant that eventually reaches a receiving water. Pollutant ... -
Modeling Automatic Meter Reading Water Demands as Nonhomogeneous Point Processes
(American Society of Civil Engineers, 2014)In this paper, an overview of a strategy for automatic meter reading (AMR) data interpretation and aggregation is presented along with the proposed stochastic models adequate for representing the intrinsic characteristics ... -
Stochastic Assessment of Long-Term Impacts of Phosphorus Management Options on Sustainability with and without Climate Change
