Dynamic Optimization Approach for Solving an Optimal Scheduling Problem in Water Distribution Systems
(American Society of Civil Engineers, 2007)A new dynamic optimization (DO) approach to solve large scale optimal scheduling problems for water distribution networks is presented. The main motivation of this research is to formulate an algorithm which is significantly ... -
Economic-Based Optimization of Panama Canal System Operations
(American Society of Civil Engineers, 2006)A network flow optimization model is developed to study the operations of the Panama Canal system. The prescriptive model chooses monthly reservoir releases and storage levels that maximize the overall benefit of the system. ... -
Can Reservoir Storage Be Uneconomically Large?
(American Society of Civil Engineers, 2006)The effect of reservoir losses on the economically optimal use of reservoir storage capacity is explored theoretically and numerically. We demonstrate that reservoir seepage and evaporation losses lead to a trade-off between ... -
Vulnerability of Drinking Water Treatment Plants to Low Water Levels in the St. Lawrence River
(American Society of Civil Engineers, 2007)This project’s main objective was to determine the vulnerability of water treatment plants (WTPs) along the lower St. Lawrence River to water level fluctuations, which included the effects of both regulation and climate ... -
Considering Location, Compliance, and Storage in Decisions on Brackish Water Resource Development
(American Society of Civil Engineers, 2006)In the past, brackish water resources have often been dismissed due to concerns over the cost gap between desalination and conventional treatment, but this simple comparison neglects several important factors that should ... -
Derived Willingness-to-Pay for Household Water Use with Price and Probabilistic Supply
(American Society of Civil Engineers, 2006)Stochastic optimization is used to estimate the willingness-to-pay (WTP) of individual households and groups of households for changes in a combination of probabilistic water supply reliability and retail price of water. ... -
Economically Driven Simulation of Regional Water Systems: Friant-Kern, California
(American Society of Civil Engineers, 2006)This paper develops and applies an economically driven simulation model for California’s Friant-Kern system, a region characterized by diverse water sources employed predominantly for commercial irrigated agriculture, with ... -
Valuing Fisheries and Wetlands Using Integrated Economic-Hydrologic Modeling—Mekong River Basin
(American Society of Civil Engineers, 2006)A healthy water ecosystem is particularly important in the Mekong River Basin, home to 75 million people who depend on its water for rice and fish production. Sound water policies will be needed to sustain current basin ... -
Achieving Water Use Efficiency in Irrigation Districts
(American Society of Civil Engineers, 2006)Irrigation districts are challenging places to achieve efficient water use when the ultimate water users do not individually own the units of water they use. The consequence is that irrigators have difficulty seeing value ... -
Calibrating Holistic Water Resources–Economic Models
(American Society of Civil Engineers, 2006)This paper presents an approach to calibrating a holistic water resources–economic model, which involves essential water resources and economic components in a consistent model. The model is formulated as an optimization ... -
Equilibrium Approach to Integrating Regional Surface Water Treatment and Limited Groundwater Pumping Capacity
(American Society of Civil Engineers, 2006)The inexpensive nature of groundwater, combined with population growth, has resulted in many aquifers being pumped at unsustainable levels. Consequently, regulators in many states have acted to limit water withdrawals from ... -
Integrated Economic, Hydrologic, and Institutional Analysis of Policy Responses to Mitigate Drought Impacts in Rio Grande Basin
(American Society of Civil Engineers, 2006)In the Rio Grande Basin of North America, water is overappropriated and demand for water grows while supplies are constrained by drought and climate change. The Basin is currently in its seventh year of drought, and ... -
Economic Optimization of Conjunctive Use of Surface Water and Groundwater at the Basin Scale
(American Society of Civil Engineers, 2006)This paper presents an integrated hydrologic-economic modeling framework for optimizing conjunctive use of surface and groundwater at the river basin scale. Integrated river basin modeling with distributed groundwater ... -
Groundwater Remediation Design Using Multiscale Genetic Algorithms
(American Society of Civil Engineers, 2006)Water resources optimization models often use spatial numerical models to approximate the physics of natural systems. The discretization of the numerical grids can affect their search for optimal solutions, in terms of ... -
Uncertainty Analysis for Coupled Watershed and Water Quality Modeling Systems
(American Society of Civil Engineers, 2006)A series of uncertainty analysis methods was applied to investigate the propagation of parameter uncertainty within a coupled model system and to evaluate the effects of uncertainty on model outputs and decision-making ... -

Optimal Design of Redundant Water Distribution Networks Using a Cluster of Workstations
(American Society of Civil Engineers, 2006)A genetic algorithm (GA)-based method for the least-cost design of looped pipe networks for various levels of redundancy is presented in this paper. Redundancy constraints are introduced in the optimization model by ... -
Effect of Forecast-Based Pricing on Irrigated Agriculture: A Simulation
(American Society of Civil Engineers, 2006)Seasonal climate prediction offers potentially useful information for water managers. However, implementing forecast information is challenging due to the probabilistic nature of forecasts and limited demonstrations of ... -
Evaluation of Programs for Regulating Withdrawal of Surface Water under the Riparian Legal System
(American Society of Civil Engineers, 2006)The frequency of water conflicts in riparian areas has increased in recent years, forcing water agencies to consider regulating water withdrawals from streams. In this paper, we evaluate permitting programs that would be ...
