Market Exchange Impact on Water Supply Planning with Water Quality
(American Society of Civil Engineers, 2004)A market-based water supply problem is modeled as an optimization problem maximizing net benefit from water use such that all the concerned parties use an economically optimal allocation considering damages due to total ... -
Groundwater Remediation Design under Uncertainty Using Genetic Algorithms
(American Society of Civil Engineers, 2005)In groundwater problems, there always is some uncertainty associated with appropriate values for aquifer parameters. Therefore an optimal remediation strategy identified by assuming a deterministic description of the system ... -
Fuzzy-State Stochastic Dynamic Programming for Reservoir Operation
(American Society of Civil Engineers, 2004)A new way of incorporating fuzzy logic concepts is introduced in order to better capture and manage some uncertainties in applying stochastic dynamic programming (SDP) formulations for reservoir operation. A model called ... -
Risk Evaluation in Water Quality Management of a River System
(American Society of Civil Engineers, 2004)A methodology for evaluation of risk for a river water quality management problem is presented. A fuzzy waste load allocation model is solved with a simulation–optimization approach for obtaining optimum fractional removal ... -
Identification of Unknown Groundwater Pollution Sources Using Artificial Neural Networks
(American Society of Civil Engineers, 2004)The temporal and spatial characterization of unknown groundwater pollution sources remains an important problem in effective aquifer remediation and assessment of associated health risks. The characterization of contaminated ... -
Robust Water Quality Model Calibration Using an Alternating Fitness Genetic Algorithm
(American Society of Civil Engineers, 2004)Presented herein is a robust approach to calibrating water quality models for water quality management using sparse field data. The calibration procedure adopts genetic algorithms (GAs) to inversely solve the governing ... -
Booster System Design Using Mixed-Integer Quadratic Programming
(American Society of Civil Engineers, 2004)A mixed-integer quadratic programming problem is proposed to locate booster stations and to identify their dosage schedules for maintaining disinfectant residual in drinking water distribution systems. Optimal booster ... -
Feasible Diversion and Instream Flow Release Using Range of Variability Approach
(American Society of Civil Engineers, 2004)A methodology based on the range of variability approach (RVA) is presented for determining the feasible combinations of flow diversion and instream flow release for a projected diversion weir. The RVA is designed to support ... -
Optimal Location and Sizing of Stormwater Basins at Watershed Scale
(American Society of Civil Engineers, 2004)Nonpoint source pollution control requires the implementation of best management practices (BMPs) at various locations in a watershed. One important aspect of the watershed strategy is to find the optimal placement and ... -
Stochastic Model to Evaluate Residential Water Demands
(American Society of Civil Engineers, 2004)The analysis and modeling of water distribution networks has been a well established engineering field for many years. However, important questions remain concerning the correct assessment of the spatial and temporal ... -
Interdisciplinary Web-Enabled Spatial Decision Support System for Watershed Management
(American Society of Civil Engineers, 2004)The process of integrating discipline-specific hydrologic, economic, and fish health models in the context of a web-enabled spatial decision support system (SDSS), WebL2W is discussed. As part of a larger research project, ... -
Managing Surface Water-Groundwater to Restore Fall Flows in the Cosumnes River
(American Society of Civil Engineers, 2004)Declining fall flows are limiting the ability of the Cosumnes River to support large fall runs of Chinook salmon. Management scenarios linking surface water and groundwater alternatives to provide sufficient fall flows are ... -

Short-Term Forecasting for Urban Water Consumption
(American Society of Civil Engineers, 2004)An approach is presented for short-term (i.e., daily and monthly) forecasting of municipal water use that utilizes a deterministic smoothing algorithm to predict monthly water use. The smoothing algorithm considers level, ... -
Leak Estimation in Water Distribution Systems by Statistical Analysis of Flow Readings
(American Society of Civil Engineers, 2004)A new method is presented for detecting the magnitude of leaks in small residential service zones (under 1,000 homes) of a drinking water distribution system. It is assumed that continuous measurements of flow rates through ... -
Optimal Layout of Early Warning Detection Stations for Water Distribution Systems Security
(American Society of Civil Engineers, 2004)Deliberate contamination is generally viewed as the most serious potential terrorist threat to water systems. Chemical or biological agents could spread throughout a distribution system and result in sickness or death among ... -
