New Hydrologic Instrumentation in the U.S. Geological Survey
New water-level sensing and recording instrumentation is being used by the U.S. Geological Survey for monitoring water levels, stream velocities, and water-quality characteristics. Several...
The USACRREL Underwater Frazil Ice Detector
A modified underwater frazil ice detector has been developed at USACRREL. This detector, which operates remotely, can automatically start deicing procedures and alert operators to the...
Risk Assessment for Groundwater Pollution Control
Prepared by the Groundwater Risk Assessment Task Committee for the Water Pollution Management Committee of the Environmental Engineering Division of ASCE. ...
CSO Solutions
EPA estimates that 1,200 cities have nearly 20,000 combined-sewer-overflow points in areas serving more than 43 million people. Their impact on waterways has become a national problem,...
Trouble on the Waterways?
Crumbling highways and bridges can cripple the U.S. economy. A lesser known transportation problem is the condition of our inland waterway system. Waterways are a cost-efficient, environmentally-sound...
Valuing Residual Emissions in Electricity Planning
Incorporating the valuation of residual emissions into calculations of social cost permits comparisons among alternative sources of electricity generation inclusive of environmental impacts....
Efficiency-Based Monitoring System Design
An analytical Monitoring Efficiency Model (MEMO) is presented to support the design of monitoring well networks at hazardous waste sites. The method simulates the migration of hypothetical...
Public Policy Issues for Sustainable Commerce
Sustainable commerce is the process of providing the material needs of a society while using natural resources no faster than they are being generated and generating wastes no faster than...
The PowerBarge
Following a brief description of the prefabricated floating PowerBarge concept, the range of application and expected cost and time savings is presented. Environmental benefits are described...
Exploring CO2 Emissions Reduction Strategies
Concern for potential climate change resulting from the greenhouse effect may be the biggest factor in energy planning in the 1990s. A 20% reduction in CO2,...
Electric Utility Planning for Greenhouse Concerns
International concerns for the potential of significant climate change resulting from the greenhouse phenomenon have focused increasing attention on the emissions of carbon dioxide and...
Interim Spent-Fuel Storage Options at Commercial Nuclear Power Plants
Although spent fuel can be stored safely in waterfilled pools at reactor sites, some utilities may not possess sufficient space for life-of-plant storage capability. In-pool storage capability...
The Low Temperature Engine System?Status Report
Computer simulations have shown the Low-Temperature Engine System (LTES), a breakthrough in application of long-established thermodynamic principles, to offer double digit power output...
The Future of Non-Utility Generation
The business of designing, constructing and operating non-utility owned electric power plants continues to evolve into the 1990s. The industry is consolidating as smaller market participants...
Will The Market in Emission Allowances Work?
The Clean Air Act Amendments of 1990 introduce a major new control program to mitigate the impacts of acid rain. The control program, which has been under debate for approximately a decade,...
Projections for Reduction in Lake Acidification From SO2 Emission Reductions
The Acid Deposition Assessment Model (ADAM) is used to assess the possible range of effects of a national acid rain emission reduction plan on lake chemistry and fish populations in the...
Optimization Models for Acid Rain Control
A series of related optimization formulations are presented for developing and analyzing acid rain control strategies. These models span a wide array of approaches and reflect a similarly...
Screening Emissions Control Measures
Under the new Clean Air Act, electric utilities will be able to choose from a wider range of sulfur dioxide emissions control options than in the past. Among the newly available measures...
Reviewing the History and Activity of FERC
Since passage of the Federal Water Power Act in 1920 (Part I of the Federal Power Act, 16 U.S.C. 791a et seq.), Congress has required those seeking to construct, operate, or maintain hydroelectric...
Facing the 21st Century with an Aging Hydro System
The Tennesse Valley Authority (TVA) has implemented a comprehensive study of their hydroelectric plants in order to extend their service life for the next 50 years into the 21st century....
