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....
Dam, Spillway and Hydropower Rehabilitation
Many older dams are in need of rehabilitation as a result of aging, deterioration, and more stringent safety standards. Current deficiencies include deterioration of original construction...
Hydro Rehabilitation?Innovative Solutions
Most hydro facilities have been in operation for many years and, consequently, must periodically have been rehabilitated. The high cost of energy, labor, materials, and financing dictate...
Brule Project Spillway Rehabilitation and Expansion
Brule Hydroelectric Project is located near Florence, Wisconsin, on the Brule River about 1.5 miles upstream of its confluence with the Michigamme River. The 80 year old dam developes...
Automation of Union Electric's Hydro-Power Plants

Acid Mine Drainage: An Overview
In the United States, acid mine water adversely affects over 6,500 km (4,000 miles) of rivers and streams. This is, however, a significant improvement over the situation two decades ago....
A Model to Predict the Production Rate of AMD
Results generated from a model to deterministically calculate the production rate of acid mine drainage compared to those generated by an empirical model are nearly identical. The model...
Wetlands for Acid Mine Drainage Treatment
Wetlands are being constructed on mined lands to treat acid mine drainage. Most of these wetlands remove a substantial amount of iron and sulfate from the water, but manganese removal...
Acid Mine Drainage Control Utilizing Fly Ash
Acid mine drainage is a serious environmental problem confronting the Appalachian region. Fly ash, the air particulate residual from the combustion of coal, is also an environmental concern...
Overview of Acid Mine Drainage Control Strategies
Since 1970, regulations requiring proper overburden sampling techniques to obtain representative geologic profiles and outline specific overburden analysis to determine acid-producing,...
Nuclear Plant License Renewal: Benefits, Feasibility, and Process
The future of power plants in the U.S. is of growing concern. The need for competitively priced and economically safe plants is a must. The reluctance of the utility industry to produce...
The Pittsburgh MAGLEV Project
A passenger transportation crisis exists in the United States which experts predict will only worsen, wasting billions of U.S. dollars. Magnetic Levitation (MAGLEV) is a promising new...
Ash Disposal at Coal Creek Station
This paper outlines the effort of two utilities to minimize the impact of an 1100 megawatt lignite fired plant's waste stream on the environment. Current regulations, poor...
Beneficial Use of Coal Ash as a Structural Fill
For decades, electric utility companies have and will continue to dispose of their coal ash in various waste disposal sites. In the state of Pennsylvania, the Beneficial Use of Coal Ash...
Fly Ash in Roller Compacted Concrete Pavement
