The Saint Lawrence River System, Atlantic Coast of Québec
At the 1:250,000 scale, Quebec has 13 773 km of coasts, 6 772 km of which belong solely to the Saint Lawrence River System. This system can be divided into six portions: river, limnetic...

Probabilistic Characteristics of Elapsed Time Between Rainfalls
The elapsed time between rainfalls is analyzed statistically using the hourly rain data at two locations: the flat-plain at Urbana, Illinois and the northwestern Appalachian foothills...

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...

The U.S. Office of Surface Mining (OSM) Proposed Strength-Durability Classification System
Federal regulations for the surface mining of coal stress proper design and construction of stable waste rock disposal areas. A key to the long-term stability of these excess spoil fills...

Precipitation Variability Effects on Modeled Soil Water Deficits
