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...
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...
An Historical Perspective on Water Resources Education
A professional education in water resources combines courses that apply sound science to meet popular needs with general knowledge on how society uses and views water. The graduate has...
Future Directions in Water Resources Education
Water resources education at the undergraduate level must change to properly prepare professionals for the 21st Century. While few changes are needed in technical content, graduates must...
Evolving Institutions for Managing the ACF Basin
The ACF basin is a case of interstate conflict in resource management. This study looks at the planning underway with regard to mechanisms for managing the basin....
Water Management by Endangered Species
In California, water management decisions are being driven by endangered species considerations. Traditional project formulation and operational criteria seemingly are unimportant. The...
Innovation and Diversification?The Key to our Future Water Supply
Water resources management must modernize, innovate, and diversify to meet the challenges of tomorrow: reliable water supply sources of acceptable quality, a cost-effective approach to...
Local Agency Regulation: The Policies and Process of Surface Water Protection
King County, Washington, adopted a Surface Water Design Manual in January 1990. This manual, which has served as a resource guide in developing similar manuals throughout the Pacific Northwest...
Ag-To-Urban Water Transfer in California: Win-Win Solutions
Water transfers from farms to the cities are widely viewed as the next major source of supply to urban California. Ag-to-Urban permanent water transfers may have negative consequences...
