Distributed Sensor Fusion in Water Quality Event Detection
(American Society of Civil Engineers, 2011)To protect drinking water systems, a contamination warning system can use in-line sensors to indicate possible accidental and deliberate contamination. Currently, reporting of an incident occurs when data from a single ... -
Possibilistic Stochastic Water Management Model for Agricultural Nonpoint Source Pollution
(American Society of Civil Engineers, 2011)Agricultural activities are the main contributors of nonpoint source water pollution within agricultural systems. In this study, a possibilistic stochastic water management (PSWM) model is developed and applied to a case ... -
Optimal Drought Management Using Sampling Stochastic Dynamic Programming with a Hedging Rule
(American Society of Civil Engineers, 2011)This study develops procedures that calculate optimal water release curtailments during droughts using a future value function derived with a sampling stochastic dynamic programming model. Triggers that switch between a ... -
Calibration of Nodal Demand in Water Distribution Systems
(American Society of Civil Engineers, 2011)This paper presents an optimization methodology to calibrate the nodal demand in the model of water supply distribution systems. The matrix analysis has been carried out to get the sensitive coefficients matrix for the ... -
Risk-Based Margins of Safety for Phosphorus TMDLs in Lakes
(American Society of Civil Engineers, 2011)A total maximum daily load (TMDL) under Section 303(d) of the U.S. Clean Water Act is the maximum amount of pollutant that a water body can assimilate without violating applicable water quality standards (WQSs). The TMDL ... -
Calibration and Optimal Leakage Management for a Real Water Distribution Network
(American Society of Civil Engineers, 2011)The aim of the paper is to present two optimization methodologies applied to a real water distribution system. The first one involves model calibration, while the second addresses the problem of optimal leakage management. ... -
CalLite: California Central Valley Water Management Screening Model
(American Society of Civil Engineers, 2011)The California Department of Water Resources (DWR) and U.S. Bureau of Reclamation Mid-Pacific Region (Reclamation) have developed a rapid, interactive screening model, named CalLite, for evaluating various Central Valley ... -
Optimal Water Allocation under Short-Run Water Scarcity in the South Saskatchewan River Basin
(American Society of Civil Engineers, 2011)This paper examines the effect on economic welfare of alternative surface water allocations in the Alberta portion of the South Saskatchewan River Basin in Canada. Growing demands for urban and instream water uses add to ... -
Decision Support System for Optimizing Reservoir Operations Using Ensemble Streamflow Predictions
(American Society of Civil Engineers, 2011)This paper investigates the value of ensemble streamflow predictions and energy price forecasts as aid to decision makers in scheduling the quantity and timing of reservoir releases for daily, weekly, and seasonal operations ... -
Planning Unidirectional Flushing Operations as a Response to Drinking Water Distribution System Contamination
(American Society of Civil Engineers, 2010)This paper addresses the issue of contaminated water evacuation as part of the response process in cases of intentional or accidental contamination of drinking water distribution systems (DWDSs). Following a previous study ... -
Historical Calibration of a Water Account System
(American Society of Civil Engineers, 2011)Models used for future based scenarios should be calibrated with historical water supply and use data. Historical water records in Australia are discontinuous, incomplete, and often incongruently disaggregated. We present ... -
Demand and Roughness Estimation in Water Distribution Systems
(American Society of Civil Engineers, 2011)To provide more accurate estimates and account for associated uncertainties, a parameter estimation methodology for water distribution systems (WDSs) that combines demand and parameter estimation processes is proposed. A ... -
Groundwater Banking in the Rio Grande Basin
(American Society of Civil Engineers, 2011)The water planning and management policies of the Rio Grande basin no longer respond to the sustainable needs of water users, environment, and international commitments of this transboundary basin between Mexico and the ... -
Integrated Planning Framework for Urban River Rehabilitation
(American Society of Civil Engineers, 2010)In 2002, 2005, and 2006, the U.S. Environmental Protection Agency (EPA) and the Department of the Army entered into memoranda of understanding to implement the Urban Rivers Restoration Initiative (URRI). The URRI is a ... -
Monitoring Design for Source Identification in Water Distribution Systems
(American Society of Civil Engineers, 2010)The design of sensor networks for monitoring contaminants in water distribution systems is currently an active area of research. Much of the effort has been directed at the contamination detection problem and the expression ... -
Energy Audit of Water Networks
(American Society of Civil Engineers, 2010)This paper presents the energy audit of a water network, which is obtained from the energy equation in integral form, and its time integration extended over a given period (day, month, or year). The analysis allows accounting ... -
Patterns in Potential Impacts Associated with Contamination Events in Water Distribution Systems
(American Society of Civil Engineers, 2011)Properly designing contamination warning systems requires an understanding of potential public health impacts for a range of contaminated water systems and a wide range of contaminants. To address this need, we determined ... -
Review of Sensor Placement Strategies for Contamination Warning Systems in Drinking Water Distribution Systems
(American Society of Civil Engineers, 2010)Contamination warning systems (CWSs) are a promising approach for the mitigation of contamination risks in drinking water distribution systems. A critical aspect of the design of a CWS is the strategic placement of online ... -
Least-Cost Design of Water Distribution Networks Including Fire Damages
(American Society of Civil Engineers, 2010)The implicit goal of water network design is to provide acceptable service during normal and peak demands and to limit damages to property and people during fires. Despite this, fire damages are seldom explicitly included ... -
SLOTS: Effective Algorithm for Sensor Placement in Water Distribution Systems
(American Society of Civil Engineers, 2010)This paper deals with methods aimed at the effective and efficient detection of accidental and/or intentional contaminant intrusion(s) in water distribution systems. The objective of this paper is to present a methodology ...
