Placing of Impermeable Underwater Membranes
An impermeable underwater membrane has been applied successfully in the construction of a lowered road section in the Netherlands. In this paper the construction technique is discussed...
Movement of Tractive Sediment from Disturbed Lands
The Smoky Creek basin of the coal area of northeastern Tennessee shows extensive evidence of tractive movement of coarse sediment from mined tributary basins into the main channel. Coal-rich...
Modeling Effects of Toxicants on Aquatic Systems
Potential effects of chemicals on biomass production in aquatic systems are extrapolated from laboratory toxicological assays. The extrapolation requires that the effect of acute toxicity...
Vacuum Assisted Pipelines Operation
In the process of upgrading the sewerage facilities for Lancaster, Pennsylvania, it was decided to combine two existing facilities into one new facility. This required the design of three...
Hydrotest Rupture of Penstuck Liner at Bath County
Bath County is the construction site of Virginia Electric and Power Company's pumped storage project. Rupture of a penstock liner during hydrotest at high pressure threatened...
Instruments Detect Dam Movement During Construction
Recent attention has been given to retrofitting electrical generation facilities at existing dams. Maintaining a safe structure during construction, and accomplishing this within a budget...
A Three Dimensional Hydraulic Jump
A study is conducted to define the three-dimensional hydraulic jump that occurs in a rectangular channel downstream of a rectangular contracted sluice gate. A sequent depth ratio equation...
Small Hydropower Development for Mining Industry
In deep mines, large refrigeration systems are employed to condition the working air to help control temperature and humidity. Large quantities of water are required to be brought into...
Field Flow Measurement of Hydro-Turbine Efficiency
Performance tests were conducted at Great Northern Paper (GNP) Company's Weldon Hydroelectric Station. The purpose of the tests was to calibrate the Winter-Kennedy taps and...
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...
Integrated Small Hydro Energy Development
Small hydro power development integrated with other renewable energy sources is economical. Civil engineering components if suitably selected and designed reduce power development costs...
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...
Bureau of Reclamation Hydraulic Laboratory
The Bureau of Reclamation used hydraulic models for the first time in 1930 in the laboratory of the Colorado Agriculture Experimental Station in Fort Collins, Colorado. In 1946 the Reclamation...
Professional Inspection of Construction
The Nation's deteriorating infrastructure is finally receiving the attention it deserves. As a result of this attention, a 5? per gallon gasoline tax has been passed. This...
Yesterday's Mainframe, Today's Desktop
Low cost, high powered engineering computer work stations are now within the economic reach of every small engineering office. While 8-bit computers can solve engineering problems, better...
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....
A Standard for the Measurement of Oxygen Transfer in Clean Water
This standard was developed to measure the rate of oxygen transfer from diffused gas and mechanical oxygenation devices to water. The standard is applicable to laboratory scale oxygenation...
Research Needs Related to the Nation's Infrastructure
The engineering community, which designs and constructs infrastructure facilities, must look for innovative ways to do a more efficient job. Although some research has focused on problems...
Infrastructure Crisis: What the Media Are Saying
In the past year and a half the national media have performed the major role in spreading the word that the nation's public works, particularly in urban areas, have been neglected...
Reagan's Lopsided Energy R&D Policy: Peril to U.S. Security?
The Reagan Administration has made (or proposed) some major shifts in the country's energy policy. It believes the federal energy research and development program should be...
