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...

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...

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...

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...

Effects of Climate Change on Water Quality
This research explores the potential effects of climate change on the quality of waters in lakes. Temperature and dissolved oxygen were considered the primary water quality variables due...

A Decision Support System for Reassessing the Operation of the Chungju Reservoir System
The Chungju Reservoir is a component of the Han River System in Korea. Chungju Reservoir consists of a main reservoir and a downstream smaller reservoir that serves as an after bay. It...

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....

Monitoring Water Quality and Use in Colorado
This paper presents the results of a two year study on the impact of irrigation water use on water quality near Greeley, CO. Data on irrigation application efficiency, deep percolation,...

Joint Pond-Wetland System Performance in Colorado
The Shop Creek retention pond and follow-up wetlands were constructed in 1989, by the City of Aurora, Colorado, and the Cherry Creek Basin Water Quality Authority to enhance urban storm...

Integration of Water Quantity and Quality Planning
This paper describes the integration of water quantity and quality objectives within the framework of a computerized interface design to assist with the difficult process of long-range...

Object-oriented Model of Colorado River Salinity
A salt balance is incorporated into an object-oriented river-basin model and applied to the Colorado River. The model simulates seasonal variations in the basin's water balance and employs...

Description of the Application of Goal Programming for Selective Withdrawal Structure Operation
Thermal stratification in reservoirs results in variations of water quality with depth. Selective withdrawal structures with outlets at different vertical locations, can be used to provide...

Conservation Measures in Urban Storm Water Management
The management of storm water runoff has been given considerable attention by regulatory agencies and practicing engineers in recent years. The current state of-the-art of storm water...

Simulating Water Supply Systems of the Raritan Basin
A recently developed interactive river-aquifer system model (IRAS) was used to study the Raritan River Basin as part of the effort to revise the New Jersey Statewide Water Supply Master...

Nakajima Subsurface Dam
A new water resource is generated by a subsurface dam. This paper presents the design, construction, and monitoring of a test subsurface dam in an alluvial valley of an island for both...

Balancing Water Allocation and Water Quality: The Model State Water Code
The Model State Water Code (hereafter called the 'Code') currently being developed by an ASCE task committee is intended to provide a source of legal norms of water allocation for use...

Water Policy Change, Implications for Pyramid Lake
Pyramid Lake is part of and is surrounded by the Pyramid Lake Indian Reservation. The river system has been administered by a Federal water master serving the Federal court system with...

Understanding the Uses of History in Water Resources Planning and Management
Understanding how water resources decisions (technical, regulatory, structural, or managerial) have been made is necessary to provide the water industry with a perception of complex human...

Joint Optimization of Groundwater Remediation and Monitoring
We describe the challenge of devising optimization methods which optimize jointly the remediation and monitoring at a contaminated site. We refer to the dual control method as a promising...
