Sedimentation Study for the Rochester, Minnesota, Flood-Control Project
In a cooperative effort, the U. S. Army Engineer District, St. Paul (NCS), and the Soil Conservation Service (SCS) planned a combined flood-control project. The SCS portion of the project...
Numerical Flood Routing for Natural Channels
A numerical model has been developed for simulating the propagation of a flood wave in a natural channel. Using this numerical model, the influence of the factors affecting the motion...
Boundary Element Analysis of Flow in Heterogenous Porous Media
The boundary integral equation method (BIEM) is an efficient numerical method which has been applied to a wide variety of engineering problems governed by a partial differential equation...
Higher-Order Methods for Transient Free-Surface Flows
One-dimensional transient free-surface flows in open channels are described by a set of quasi-linear hyperbolic partial differential equations, called the Saint-Venant equations. Numerical...
The Design and Construction of the Bartletts Ferry Labyrinth Weir Spillway
The discharge capacity of the Bartletts Ferry Project has been increased 165 percent by the addition of a labyrinth weir spillway. The hydraulic design was based on a published design...
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...
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...
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...
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....
Using CADD for Fun and Profit
American Bridge Engineers, a Pittsburgh full service engineering, architecture and planning firm, is still exploring the full capabilities of its CADD (computer aided design and drafting)...
Micros Can't Stand Alone
Unlike mainframes, which usually come as turnkey systems, microcomputers require separate accessories. Add-ons for micros include storage devices, memory boards, video boards, communication...
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,...
