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...

Object-oriented River System Simulation
This paper describes an object-oriented approach to river basin simulation modeling that is event driven rather than time driven as in most river system simulation models. At the heart...

RSS: A Construction Kit for Visual Programming of River Basin Models
With the ever increasing pressure on environmental resources, there exists strong interest in river basin models which can be used to simulate proposed policy alternatives. Traditionally,...

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...

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....

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...

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...

Hydrologic Analysis of Leveed Interior Areas
Flood damage reduction projects that include levees or flood walls usually involve special problems associated with isolated interior areas. Storm runoff patterns may be altered and remedial...

Global Approaches for the Nonconvex Optimization of Pipe Networks
Because the pipe network problem is nonconvex, two global search schemes, MULTISTART and ANNEALING, are employed to permit a local optimum seeking method to migrate among various local...

Non Contact, Remote Sensing of Buried Water Pipeline Leaks Using Infrared Thermography
Subsurface water pipelines, sewer and buried utilities throughout America and the rest of the world range in age from hundreds of years old to brand new. They all have, however, one fact...

The Impact of Global Warming on Water Resources: Overview and Implications for Coastal California
In the past two years, impressive evidence has accumulated that global warming is occurring and is related to the increase in greenhouse gasses. The impact of the warming process on water...

Empowering Stakeholders Through Simulation in Water Resources Planning
During the past two years, researchers at the University of Washington (UW) have had the unique opportunity to facilitate and observe the development of drought planning activities associated...

The Potomac Experience?A Forerunner of DPS
Thirty years ago, dramatic events were about to begin in Potomac River basin with the publication of a report of study recommending 16 major reservoirs and hundreds of small ones to solve...

The Role of Object Oriented Simulation Models in the Drought Preparedness Studies
One of the major activities in the U.S. Army Corps of Engineers, Drought Preparedness Studies (DPS) has been the development of water resource simulation models for each study site. This...

Demonstrating Competition for a Limited Resource in the Cedar/Green Basins
An object oriented model building tool is used to develop two river basin simulation models. The models will be used to help manage the water resource during dry years in the Cedar and...

Multiparty Model Development Using Object-Oriented Programming
The Massachusetts Water Resources Authority (MWRA) has taken advantage of recent advances in object oriented programming to build a flexible input and output model of its water supply...

Agricultural Water Conservation Technology Transfer
Efforts to implement computer programs which encourage water and energy conservation in the Columbia Basin, are described. Irrigators use the irrigation scheduling program to receive recommendations...
