Optimal Utilization of a Multi-Reservoir Water Distribution System
A water supply distribution system planning model (DSPM) has been developed using a linear programming approach. Unlike the conventional formulation, the water demand requirements are...

Reliability Curves for Reservoir Performance
Seattle District, U.S. Army Corps of Engineers, has developed a family of reservoir guide curves that illustrate reliabilities when storage conditions gradually decline from 98% to as...

Geographic Information System Application: Water Right Places of Use as Polygon Attributes
A Geographic Information System (GIS) was tested for potential use as a water resource management tool by application to a ground water study area. Because of the limitations of the particular...

GIS Reconstruction of Exposure to Water Supply Contaminants
Groundwater pollution resulting from improper waste handling practices in the aerospace industry contaminated the water supply in Tucson, Arizona. State and federal health officials concluded...

Stochastic Forecasts in Reservoir Planning and Operations
The factors involved in stochastic forecasts of water supply and demand are discussed in relationship to reservoir planning and operating decisions....

Characterization of Uncertainty in Reservoir Operations
The development of operating policies for complex reservoir systems typically requires a consideration of various system component interrelationships and several conflicting operating...

Hydrologic Forecasting?What are the Issues?
The paper briefly describes hydrologic forecasting techniques that are being used today and raises issues that should be addressed as new hydrologic forecast systems are developed and...

Using Forecasts to Improve Reservoir Operations
This review considers methodologies that have or can be employed to incorporate streamflow forecasts into reservoir policies and operating decisions. These include the use of streamflow...

The Development and Use of Policy Statements in River Simulation Models
There are a number of ways in which the physical operation of a river system can be expressed in simulation models. Most of the earlier simulation models have incorporated the operating...

Advanced Decision Support Systems for Environmental Simulation Modeling
Some new computer approaches for integrating simulation models into water-quality management and planning are described. A system for integrating models, databases and decision-support...

Solute Transport Modeling under Unsteady Flow Regimes: An Application of the Modular Modeling System
Many existing solute transport codes rely on the assumption of steady (i.e. time-invariant) flow. This assumption severely limits such models, as accurate simulations often require realistic...

Stochastic Reservoir Operation under Drought with Fuzzy Objectives
Biobjective reservoir operation under drought conditions is investigated using stochastic dynamic programming. As both objectives (irrigation water supply, water quality) can only be defined...

Seasonal Water Quality Management Given Sparse Data
An approach for designing robust seasonal water quality management programs for river basins with sparse or short flow records is presented. This approach uses Markov chain modelling and...

Imprecise Probability and Water Resources Decisions
In water resources engineering weak information would correspond to circumstances when the record is extremely short relative to the mean rate of occurrence of important design events,...

Development of a Raw Water Master Plan Model to Assist Long Range Drought and Water Conservation Planning for the City of Louisville, Colorado
The City of Louisville, a municipal corporation charged with meeting the water demands of almost 5,000 water accounts and faced with a diminishing supply of available senior water rights...

Application of Computer Support for Water Quality Management
A Computer-Aided Support System for operation of the QUAL2E-UNCAS river water quality model has been developed for the California Regional Water Quality Control Board, North Coastal Region....

CASS for Evaluating Hg Contamination in Clear Lake, CA
Characterization of ecosystem contamination and evaluation of potential mitigation schemes represent two of the most immediate challenges to management of water resources. Heavy metals...

Graphics User Interface for Water Quality Model Calibration
The UC Davis Water Resources Modeling Group developed a unique Graphical Use Interface (GUI) in the Microsoft Windows environment to facilitate use of the stream mode QUAL2E for the Russian...

Research Needs in Water Resources Planning and Management
When the WRPMD was formed, expectations about research were high, but in this new era we must reexamine the role of research. The greatest policy need for the water industry is institutional:...

Remarks on Computer-Use History in Water Resources
Over the past 50 years, use of electronic computers has radically changed water resources engineering practice. It has enhanced capabilities, reduced costs and improved reliability. It...
