Hydro Power
The Kerckhoff 2 Hydroelectric Power Projects adds 140 MW to the capacity of the San Francisco area's Pacific Gas & Electric system. No new dam was needed; only a 4-mile...
Dredge Spoil Disposal Predictions and Performance: A Case History
A 146-acre dredge spoil disposal facility was constructed in Baltimore Harbor that received 3. 4 million cubic yards (2. 6 million cubic meters) of dredge spoil generated from construction...
Current Issues in Rock Dredging
An attractive alternative to the use of explosives for deepening shipping channels is the improvement of the rock cutter suction dredger. But, assessing the capability and design parameters...
Mixed Layer Modelling of Stratification in Lakes
Mathematical models for vertical heat transfer processes in lakes and reservoirs are grouped into two classes: diffusion models and mixed layer models. In recent years much of the progress...
Operation of Glen Canyon Dam Spillways--Summer 1983
Flood control at Glen Canyon Dam is provided by a 41-ft (12. 5-m) diameter tunnel spillway in each abutment. Each spillway is designed to pass 138,000 ft**3/sec (3907. 7 m**3/sec). The...
Modeling Aeration Devices for Glen Canyon Dam
The 41-ft (12. 5-m) diameter tunnel spillways at Glen Canyon Dam experienced major damage during the 1983 spring runoff. This damage was initiated by cavitation. Hydraulic model studies...
Cavitation Inception from Cylindrical Holes
The inception of cavitation due to circular holes in a boundary is studied. Laboratory experiments were conducted to define limited cavitation as a function of the hole depth to diameter...
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...
Guidelines for Transmission Line Structural Loading
Procedures are provided for the selection of design loads and load factors based on the latest research and state-of-the-art design techniques. This selection has an effort on the reliability...
Afloat on the China Sea
In the summer of 1982, the Science and Technology Commission of the People's Republic of China invited four United States tunnel experts to come to China to engage in technical...
Design of Port and Coastal Structures for Ice Forces
Design of ice-affected port and coastal structures cannot be addressed in a few single specific terms, but must instead account for a matrix of elements differing at each site. Evaluation...
Lining Tunnels: Toughest Concreting Job?
Concrete linings for water supply tunnels must resist sulphate and other chemical attack, not contribute pollutants to the water it is carrying, and not leak for its design life, which...
Cold Regions Engineering in Norway
The use of insulating materials is a key factor in cold regions engineering in Norway. It is applied in road construction in areas where frost heave and reduced bearing capacity would...
Bloomington Lake�Potomac River Water Resources Project
The recently completed $174 million Bloomington Lake project has improved flood control and water quality to the benefit of millions of people downstream. The headwaters of the Potomac...
Bibliography on Ocean Energy
With the prospect of an increasing shortage of energy resources, there has been a growing interest in renewable alternative sources of energy. An increasing effort is being directed towards...
Fiber Reinforced Concrete
In the past 10 years or so, concrete reinforced with fibers one or two inches long has begun to be used, first on a demonstration and experimental basis, then in major everyday applications....
Shanghai Tunnel Projects Spur Construction Innovations
Since underground construction in soft ground is newly developed in Shanghai, there is little experience there as compared to what is known for specific sites in other countires. Well...
Energy in the Man-Built Environment
Proceedings of the Specialty Conference on Energy in the Man-Built Environment, held at the Lodge at Vail, Vail, Colorado, August 3-5, 1981. Sponsored by the Urban Planning Development...
Japanese Tunnel Design: Lessons for the U.S.
