Evaluating Sensitivity of Hydraulic Control Optimization Models
Sensitivity of hydraulic control optimization models to variation in gradient constraints is examined. Monte Carlo simulation is used in conjunction with repeated optimization runs to...

The Application of Streamflow Duration Curves in Water Resources Engineering
Streamflow duration curves are a useful graphical and analytical tool for illustrating the relationship between the frequency and magnitude of daily streamflow. They are commonly used...

Fort Bend County Surface Water Supply Study
Fort Bend County encompasses approximately 876 square miles in southeast Texas near the Gulf of Mexico. The County's sole source of potable water is groundwater, which supplied 28 million...

Instream Flow Policy: An Alternative to Minimum Flowby
The limitations of current instream flow policies based on the concept of minimum flowby are discussed. An alternative policy based on sharing the available resource among competing uses...

Water 2050-Supply for the Portland, Oregon Metropolitan Region Using the Integrated Resource Planning Process
This paper presents information about the long range regional water supply planning work that is being conducted in the Portland, Oregon metropolitan region. An integrated resources planning...

Salt River Project Strategic Water Resource Plan
This paper discusses the results of the Salt River Project Strategic Water Resource Plan - Phase I: Assessment & Potential Strategies. The objective of Phase I of the Strategic...

Thoughts of Reservoir Management Studies
Changing water use patterns and priorities, the high cost and uncertainty of developing new supply sources, increasingly stringent environmental regulation, and the desire and need to...

Mitigation of Non-Point Source Pollution Impacts on Groundwater Aquifers: A Case Study
This paper presents methodologies applied to a regional-scale project to study the potential impacts of storm runoff on groundwater aquifers that store sole source water supplies in Morris...

Site Characterization by Artificial Neural Networks
Recently, an optimal groundwater management model has been developed to treat groundwater remediation problems at Lawrence Livermore National Laboratory (LLNL). The objective of the model...

Aquifer Remediation Design: Nonlinear Programming and Genetic Algorithms
Nonlinear programming and genetic algorithm solutions of a pump-and-treat aquifer remediation design model are presented and discussed. These models find the minimum cost design of the...

Genetic Algorithms and Neural Networks: Do Pluralized Techniques Hold Any Advantages for Designing Groundwater Quality Assurance Systems?
Methods have recently been developed for designing groundwater monitoring and pollutant containment systems. These methods rely on a variety of new and classical optimization and modeling...

Integration of Reliability, Uncertainty and Optimization in Hydraulics Systems: Structural Reliability
The focus of this paper is to provide an overview of analysis and optimal design of systems in which the system reliability is dependent upon the structure of the system (such as the layout...

Designing Optimal Reliable Multiquality Water Supply Systems
A methodology which integrates optimal design and reliability of a multiquality water supply system is presented and demonstrated. The system constructed is able to sustain prescribed...

A Decision Support System for Administering Water Rights in an Alluvial Aquifer
A previously developed basin scale surface-ground water simulation model has been incorporated into a micro-computer based decision support system that simulates the transient ground water...

Colorado River Decision Support System
Colorado is developing its own tools, such as the Colorado River Decision Support System (CRDSS), to evaluate alternative strategies and establish an informed and factual position regarding...

Geographically Distributed Decision Support; The Tennessee Valley Authority (TVA) TERRA System
The Tennessee Valley Authority (TVA) has a long history of managing the water provided by the Tennessee River and its tributaries. TVA is responsible for such diverse water interests as...

Modeling Temperature Impacts on Salmon Survival
Among research goals at the University of California-Davis are the development and application of mathematical models to study water quality impacts on threatened and endangered species....

Water Conservation and Delivery Flexibility in the Imperial Irrigation District Through Lateral Interceptor Systems
The lateral interceptor concept was conceived in the wake of a water conservation effort to reduce several sources of water loss typical of irrigation districts. These sources include...

Building Groundwater Optimizers That Respond to the Needs of Decision-Makers
Optimization methods are being sought and employed to design systems that remediate contaminated groundwater regions (and, in fact, the subsurface in general) with increasing frequency....

Arizona Groundwater Management Alternatives
Sustainable groundwater management policies are examined through the use of a hydrologic-economic impact model of Arizona surface and groundwater use. Present water use practices were...
