Modeling Analysis for Management of Artificial Recharge
The objective of these groundwater and sediment modeling studies is to determine the net change in storage and potentiometric levels within the Bunker Hill Groundwater Basin resulting...
Leaching Analysis of Coal Mine Spoil Material
Arch Mineral Corporation has conducted a column leaching study to analyze the leaching characteristics of surface coal mine spoil material in order to predict post-mining groundwater quality....
A Quantitative Assessment of Surface Water Resources for Coal Slurry Pipelines Originating in Southwest Virginia
In view of the high streamflow variability, preliminary quantitative assessment was made of the capacity requirements and low-flow frequency characteristics of offstream reservoirs needed...
Optimal Real-Time Operation of a Cascade of Hydropower Plants in Central West China
The Longxihe River hydropower system consists of four hydropower plants in series. The four reservoirs are used for flood control and power generation. Among the four reservoirs, only...
Saline Water Disposal from a Coal Bed Methane Recovery Well Field
A conceptual engineering approach for low cost management of production water from coal bed methane recovery wells is presented. The approach is applicable for production water that contains...
Hydro-Thermal Power Plants with Pumped Storage
The concept of pumped storage can be justified through the development of hydro-thermal power plants. The hydraulic equipment for power plants of this kind is available in the market meeting...
Alternative Layouts for Hydro Headrace Tunnels
The recent development of tunnel boring machines capable of excavating hard rock at virtually any grade together with the Norwegian experience in compressed air surge tanks provides the...
Sedimentation in Small Hydropower Reservoirs
Small-scale hydropower projects, which usually include reservoirs of limited size, may inherently incorporate severe sedimentation problems. The ratio of reservoir volume to sediment inflow...
Hydrogen Cycle Peak Power at Low-Head Sites
A major draw back to further development of low-head hydro power is that it usually uses run-of-the-river operations. The storage potential for peaking power production that large reservoirs...
Walden Hydroelectric Power Project
The Wallkill River at Walden, New York, produced hydroelectric power from 1909 to 1966. Using turbines dating back to the original hydroelectric development, the Walden hydroelectric station...
Water Supply Supplemented by Airport Storm Runoff
The quality of natural and induced storm water runoff from Oahu's Honolulu International Airport (HIA) and four outer island airports in Hawaii was evaluated for water supply...
A Systems Approach to the Assessment of Water Supply, Treatment, Storage and Distribution Systems
To focus on the needs of a system at present and in the future and to foresee potential problem areas prior to their occurrence, it is advisable for the management of a water utility to...
Sensitivity of Model Choice in Reservoir Design
The Box-Jenkins method of model construction and tests of model adequacy and fit are applied to a reservoir design problem. The sensitivity of the stochastic models used to generate synthetic...
Economics and Groundwater
The increasing use of groundwater has resulted in greater lifts, and coupled with increased energy costs is focusing more attention on the economics of groundwater use. The proceedings...
Structural Engineering in Nuclear Facilities
The papers in this publication cover the general theme of civil and structural engineering as they are applied to nuclear facilities. Traditional topics include seismic analysis, impactive...
Guidelines for the Seismic Design of Oil and Gas Pipeline Systems
Current knowledge on the practice of earthquake engineering for oil and gas pipeline systems is presented. Such systems typically consist of buried oil, gas, or product pipelines and aboveground...
Superhydro
In 1986, when its six turbine/pump-generator/motor units will be in operation, the Bath County Pumped Storage Hydroelectric Project in Virginia will be the world's largest....
EPA's New Land Disposal Rules�A Closer Look
Despite some initial enthusiasm for the new EPA regulations on land disposal of hazardous waste, many critics are now expressing concern for the long-term environmental impact. The dependence...
Lining a Pond to Contain Uranium Tailings
Impermeable pond linings combined with geotextile fabric underlinings are a recent innovation in industrial storage pond construction. A case history of a pond site in New Mexico illustrates...
Pre-Engineered Metal Buildings: The Story Behind Their Rapid Growth
In 1964, pre-engineered metal buildings accounted for 24% of new non-residential, low-rise construction. By 1981, that figure had jumped to 56%. Behind that rapid growth are some very...
