Development of the Dredging Wheel
The 'bucket line' dredge and 'cutter suction' dredge are two distinct types of equipment. The cutter suction system has developed more...
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...
Mechanics of Mudflows
A Bingham model is adopted to study the fluid mechanics of mudflows. Equations for predicting the transition from laminar to turbulent flow in an open channel are formulated and verified...
Local Scour at Fish Rocks
There is a growing interest in the enhancement of rearing habitat for juvenile anadromous fish in the Pacific Northwest. This has focused attention on the need for a better understanding...
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...
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...
Planning a Resource-Compatible Low Head Waterpower Development
Responsible development of waterpower potential is a significant aspect of comprehensive water resource planning. Recent interest in small scale hydro projects has generated concern among...
Computer-Aided Preliminary Optimization Model for Low-Head Micro-Hydro Installations
It is demonstrated with applications, that the use of a computer-aided preliminary optimization model can help evaluate the overall technical and economic characteristics of low-head hydro...
Current Hydraulics Research at the Iowa Institute of Hydraulic Research
The Iowa Institute of Hydraulic Research is engaged in fundamental and applied research on a broad range of fluid mechanics and hydraulics problems. The history and organization of 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,...
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....
Recent Advances in Engineering Mechanics and Their Impact on Civil Engineering Practice
The emphasis of these proceedings is on contributions and advances in the areas of solid and fluid mechanics that advance civil engineering practice. The main topic considered are, computers...
Subway
Peachtree Center Station is the only mined transit station in the U.S. using reinforced native rock for permanent support. The station, serving some 34,000 patrons a day, is the largest...
Journal of Engineering Mechanics
The Journal of Engineering Mechanics covers activity and development in the field of applied mechanics as it relates to civil engineering. Research on bioengineering, computational mechanics, computer-aided...
How to Create and Present Effective Slides
Speakers often devote hours of preparation to the main body of a prepared text, but fail to allow ample preparation time to creating their visual aids. Slides, visual aids which should...
Addressing Societal Needs of the 1980's Through Civil Engineering Research
Critical issues facing society in ten subdisciplines of civil engineering are defined and the research required to provide solutions to these issues in each area is identified. The ten...
Tall Building Systems and Concepts
The structural, mechanical and electrical systems of tall buildings are explored. The eight areas of focus are, structural systems, mechanical and service systems, electrical systems,...
Synthetic Fabrics for Reinforced Embankments
Non-woven permeable synthetic fabrics have been used in engineering applications for the last ten years. Considerable research has been conducted throughout the world since the first geotechnical...
The Concrete Canoe: A Technological Challenge
In 1970 the first concrete canoe was built, and since that time many colleges and universities have built and raced concrete canoes. The Union College (Schenectady, NY) Stone Boat Club...
