Evaluating Advanced Technologies for Acid Rain Compliance
Technological innovation in emissions control of acid rain precursors has made possible increasingly stringent control requirements for coal-fired power plants. A key challenge for potential...

Stabilized Fly Ash Cover for a Municipal Waste Landfill
The study reported herein and several recently related projects have been aimed at reducing the hydraulic conductivity of fly ash and physiochemically fixing any potential leachable metals....

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...

Review Notes on Cohesive Sediment Erosion
Comments are made on issues related to surface and mass erosion phenomena associated with cohesive sediment beds, and the entrainment of fluid mud. The rate process theory is recapped...
