Numerical Modeling of Flow in Hydropower Intakes
To reduce high mortality of downstream migrating juvenile salmon at hydraulic turbines, traveling screens are used to guide the juveniles into a bypass channel for safe passage. However,...
Hydraulic Analysis of Water Transmission Flowing Party Full
The hydraulic behavior of a transmission line that flows full along only part of its length is more difficult to analyze than a completely full line. Unsteady open-channel and closed-conduit...
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...
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...
Unsteady Mixing of a Buoyant Jet into a Reservoir
A buoyant effluent was dyed with fluorescent dye on two occasions to determine its mixing characteristics and flow path through a small hydropower reservoir located in south central Arkansas....
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...
Research in Hydraulics at California Institute of Technology
Activities are centered in the W. M. Keck Laboratory of Hydraulics and Water Resources. Research projects active at the Laboratory reflect a continuing commitment to traditional areas...
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,...
Superplasticizers: Reducing Water in Concrete
Superplasticizers or high-range water reducers are new types of chemical admixtures which when incorporated into concrete can cause significant increases in its slump but without any loss...
Boston Tunes Up Water System
In 1977, Boston's water supply system had so many leaks and so many unmetered or undermetered customers that only about half the water entering the system was accounted for....
Ditch Flow Program
Seventeenth in the CE Computing BASICS series, the program in this article is for simplifying drainage calculations. The program will provide critical and normal velocities, depths and...
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...
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...
Current Status of Urban Hydrology in Finland
Due to a smaller scale of urban problems on Finland, active research work on urban hydrology began as late as in the mid-1970's. The major urban hydrology and related studies...
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...
Journal of Hydraulic Engineering
The Journal of Hydraulic Engineering accepts original contributions that describe the analysis and solutions of problems in hydraulic engineering. Technical Notes may present a problem, without solution,...
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...
