Coal Mine Subsidence and Structures
Underground coal mining has occurred beneath 32 multiplied by 10**9m**2 (8 million acres) of land in the United States and will eventually extend beneath 162 multiplied by 10**9m**2 (40...
Extent of Water Quality Effects of Dams?A National Viewpoint
An overview of phosphorus impacts on impoundments, a subset of the contents of the Dam Water Quality Report is presented. The U.S. Environmental Protection Agency (EPA) is the lead investigator...
Reservoir Safe Yield Evaluation Using Simulation
The safe yield available from surface water impoundments serving the City of Portsmouth, Virginia, was evaluated, and the sensitivity of the reservoir system to several factors was investigated....
Risk Consideration in Water Supply Reservoir Capacity Design
This study develops a method for estimating the risk in reservoir capacity design by applying frequency analysis to the mass curve method. It provides a means for the engineer to use familiar...
Water Assurance Districts: A New Concept in Local Government
Society has long utilized local governmental units to implement numerous water management functions. This paper discusses a new and relatively unique local organizational structure now...
Artificial Recharge: Key to Scottsdale's Future
The City of Scottsdale, Arizona has begun planning its strategy for meeting its future needs by recognizing artificial recharge, subsurface storage, and recovery as an integral component...
Underground Storage in Urban Stormwater Management
The use of underground pipe detention basins is discussed. These basins mitigate the frequency of localized flooding and sewer surcharging by effectively increasing the flow capacity of...
Computer Based Master Plans Manage Water Resources
Scottsdale is pursuing water and wastewater master planning with the goal of implementing a proactive water resources management policy. To prepare dynamic master plans with the above...
A Study in Nuclear Decommissioning
The Gentilly-1 nuclear power plant two year decommissioning project launched a series of firsts for the nuclear power industry. It was the first commercial sized plant in the world to...
Injecting an Oxygen Fix
Seasonal dissolved oxygen deficiencies are an old problem in hydropower discharges from deep impoundments. At the Richard B. Russell Dam near Savannah, Georgia, an innovative solution...
Underground Storage Tank Program and Its Implications
National concern over leaking underground tanks storing hazardous materials and wastes has resulted in the implementation of the 1984 Amendments of RCRA, which include the requirement...
Trenchless Techniques for Pipeline Installation, Renovation and Replacement
New construction methods have been developed primarily in Europe and Japan for underground pipeline work. The new methods, known as trenchless techniques, are primarily used when existing...
Mine Induced Subsidence
Effects on Engineered Structures
The influence of mine subsidence on engineered structures is a growing concern of the United States coal industry. This book contains a collection of case histories of the control and...
