Simulation of Water Quality Processes in the Chicago Waterway and Upper Illinois River Systems
The U.S. Environmental Protection Agency QUAL2E-UNCAS (QUAL2EU) computer program was used to simulate the water quality processes in the Chicago waterway and Upper Illinois River Systems....
Optimization of Operations?The Manitoba Hydro Experience
As part of a decision support system, Manitoba Hydro implemented a comprehensive optimization model for operations planning in the mid 1980's (Barritt-Flatt and Cormie 1991). Since that...
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,...
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,...
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:...
Optimal Planning of Combined Sewer Rehabilitation
The need to rehabilitate many of the existing sewer systems to keep them operational is evident. The development of a rehabilitation plan that optimizes the use of funds is the first step...
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...
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...
Geothermal and Hydropower Production in Iceland
This paper will first consider the technical aspects of both hydropower and geothermal power production in Iceland. Then the economic consequences of the alternative utilization of these...
Use of a Statistical Model to Forecast Future Wastewater Flows
Future wastewater flows are generally predicted based upon an assumed rate of population and industry growth within a treatment facility's area of influence. In a community with limited...
Price Elasticity and Conservation Potential
Water conservation programs usually contain pricing incentives for users to limit water consumption. This analysis uses data from the Portland, Oregon water system as an example of both...
Interactive Decision Support for Hydrologic, Hydraulic, & Instream Flow Criteria
Most often, impacts on natural resources from alternative river discharges are not quantified. The personal computer (PC) can provide access to useful techniques for analyzing multiobjective...
Reservoir Management and Thermal Power Generation
Thermoelectric power stations on regulated rivers may cause violations in stream temperature standards if the dilution water from the upstream reservoir is not adequate. However, it is...
Alternatives Analysis Using Two-Dimensional Modeling for the Owensboro Bridge and Approaches
The Federal Highway Administration plans to design and construct a new bridge over the Ohio River near Owensboro Kentucky. A hydraulic model with two-dimensional capabilities was utilized....
Dynamic Analysis and Design Considerations for High-Level Nuclear Waste Repositories
This proceedings,
A Structural Analysis System
In this paper, the importance of the structural analysis in accordance with the construction progress was emphasized to accurately predict the structural behavior of prestressed concrete...
Computer Analysis of Cable-Stayed & Suspension Bridges
The finite element structural analysis of long span bridges is an area of research that has been studied within the past thirty years since the development and emergence of the digital...
