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...
Willow Creek Dam--To Be or Not To Be
In Heppner, Oregon, several alternatives for flood control were considered. A concrete gravity dam constructed using roller compaction methods was selected because of the greatly reduced...
Pipe Spillway Plunge Pool Design Equations
An equation is given to determine if scour holes will beach and widen excessively. For nonbeaching scour holes, dimensionless equations are given for the progression of scour with time...
Avoiding Cavitation Damage to Hydraulic Structures
Cavitation damage often may be avoided by not allowing cavities to form. Where boundaries are not deeply submerged, their shape must be exactly correct, irregularities must be very small,...
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....
Fishways--Historical Assessment of Design Practice
Fishway design has evolved over the years in a conservative fashion. Research has led to the development of some innovative structures, but costs and water usage have been high. Conservative...
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...
Hydropower Plant on an Irrigation Pipeline
A 940-kW hydroelectric plant was installed on a renovated irrigation pipeline at a Bishop, California ranch. On its way to the ranch, the falling water now generates an average of 4. 2...
Negotiating a FERC License for the Terror Lake Project
Recently, a long, intense negotiation was completed over the Terror Lake Hydropower project on Kodiak Island in Alaska. The bargaining over the Federal Energy Regulatory Commission (FERC)...
Camp Far West Hydroelectric Project--From Concept to Reality
The project has progressed through a series of predictable development stages including a detailed feasibility study, major project licensing, an environmental Initial Study and Negative...
Plastic and Other Limit State Methods for Design Evaluation
These proceedings consist of seven papers dealing with the topic of the design of complex structures using limit state methods. The emphasis is on the role of plastic or limit load techniques....
Innovative and Affordable Residential Development
The rise in cost of land, housing construction and financing over recent decades has seriously reduced the number of those eligible for home loans. These and other cost factors are carefully...
Applications of Small Computers in Construction
These proceedings are from a technical session sponsored by the Task Committee on the Application of Small Computers in Construction of the Construction Division. Five papers are presented....
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...
Structural Plastics Design Manual
The structural behavior of plastics reflects a number of characteristics different from those of the metal, lumber, and concrete materials familiar to most design engineers. This manual...
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...
Practical Guidelines for the Selection, Design and Installation of Piles
This report provides an objective practical basis for the design and construction of pile foundations. Potential problems and uncertainties in pile design and construction are emphasized....
Jordans Precast Airport
The design and construction of the New Queen Alia International Airport in Amman, Jordan required extensive innovation and site adaptation to integrate international standards with the...
Temperature Effects on Lasers
While lasers have markedly improved the accuracy of engineering, air temperature gradients can reduce that drastically. Based on a sewer project that used lasers to align all the pipe,...
Alluvial Fans: Novel Flood Challenge
After disastrous floods hit Cabazon, Calif., engineers faced the challenge of balancing concerns about protecting property and life (by limiting or prohibiting construction) against the...
