Thermal Monitoring of Leakage Through Dams
The technique involves very accurate temperature measurement at shallow depth below the reach of the surface diurnal cycle. Temperatures respond to subsurface water movement (with advective...
Rehabilitation of a Pump/Turbine
Between 1964 and 1968, eight 212 in pump discharge diameter Baldwin-Lima-Hamilton vertical pump/turbines with Westinghouse motor/generators were installed in Philadelphia Electric Company's...
Uprating Francis Turbines Provides Additional Energy
The use of existing powerhouse, penstocks, dams and unit configuration, all provide for a quick cost effective method to increase output from an existing turbine installation. This paper...
Fishery Issues Slow Boardman River Redevelopment
At issue was the requirement of the Michigan Department of Natural Resources (MDNR) and the U. S. Fish and Wildlife Service to require the establishment of fish ladders at the hydro sites....
Hydropower Contract Conditions for Civil Engineering Works
Norwegian types of contract documents for hydropower construction work - especially the underground parts - have long had the reputation of being flexible as opposed to the traditionally...
HydroMAX; Computerized Hydropower Scheduling
The New England Power Exchange (NEPEX) is currently using the HydroMAX Program to schedule daily hydropower operations for the 17 stations in the 11,250 square mile Connecticut River Basin....
Generic Power System Stabilizer Design
The object of this paper is to describe the design considerations of a microprocessor based power system stabilizer operating through excitation control as applied to a multi-unit pumped...
Increasing Hydropower Operating Efficiency
A method is described for determining the most efficient use of hydro units in a multiple unit hydro plant. In a multi-unit plant enough flexibility exists to load a chosen set of units...
Independent Review of Truman Dam Operation
The Truman Dam in Missouri was constructed by the Army Corps of Engineers in 1979 as a pumped-storage facility. Due to fishkill and other controversies, the pumpback feature of the project...
An Economical Approach to Receiving Coal by Rail in the Sub-Arctic Environment
During the period 1983 to early 1985 a multimillion dollar coal transfer facility was designed and constructed in Seward, Alaska. The facility transfers coal from rail cars to temporary...
Installation of the Port of Singapore's SPM System
To achieve an increase in refining capacity from 70,000 barrels per day to 170,000 barrels per day, a local oil refining company entered into an agreement with the Port of Singapore Authority...
Perforated Wave Barriers in Small Boat Piers
Perforated breakwaters can be used to reduce the energy and the height of waves entering small boat harbors. By not extending the breakwater to the bottom interference with littoral drift...
Expansion of the Electro-Coal Transfer Terminal
This paper briefly describes renovation and expansion of the coal and phosphate marine terminal in Davant, La. The program included: replacement of existing berths damaged by marine accident;...
Additional Benefits from Channel Improvements
This paper describes techniques used to quantify three types of benefits resulting from enlarging the Houston Ship Channel. These benefit types are vessel casualty reduction, delay reduction...
A Study of the Potential for Groundwater Contamination by Alcohol Blended Gasolines
This paper describes the increased solubility of gasoline-hydrocarbons in groundwater when alcohols are used as octane enhancement additives and the effects of 'gasohol versus...
Power from the Incineration of Wastewater Sludge
The City of Kansas City, Kansas recently completed an upgrading of their existing primary treatment and sludge handling system in preparation for the addition of a high purity oxygen activated...
Assessment of Analytical Techniques for Monitoring Petroleum Waste Land Treatment Systems
Optimization of wastewater land treatment effectiveness requires current knowledge of the microbiological ecosystem. Environmental parameters must be measured if they are to be adjusted...
Future Hydrothermal Power of the United States
Public indignation toward nuclear-power expansion, and dwindling oil and gas reserves dictate the needs to look for alternative-power sources, such as coal and water. It is a prime time...
Studies of Long-Term Water Losses
The water-loss time series are formulated for the studied watersheds in the Ohio River Basin through the use of the law of water balance to the system inputs and corresponding outputs....
Coupling Free Vortex Energy Dissipation with Sediment Control
The paper reports on studies showing that sediment control down to the abrasive limit of 30 micron sand and energy dissipation can be achieved simultaneously with a Teacup free vortex...
