Moose River Air Chamber Design and Performance
The Moose River Hydroelectric Project is a 12.5 MW development located in upstate New York. It employs an underground air chamber to protect the unit and power tunnel from pressure surges...

HYOPS?Maximizing the Value of Your Hydro River System
This paper presents a microcomputer based software system, HYOPS, to optimize the operations of a series of hydro plants on a river system. The model can accommodate up to 10 plants which...

Instream Flow and Energy Production Studies for Hydro Relicensing
A methodology for assessing the effects of alternative flow release scenarios on both aquatic habitat and on energy production was utilized during instream flow studies at a 72-MW hydroelectric...

Computerized Measurement of Turbine Flow and Performance, Including Penstock Protection
The application of computer technology now makes it possible to measure turbine flows accurately, reliably and economically. The measurement is based on the differential pressure produced...

Financing and Marketing Feasibility Tests for Proposed Federal Hydroelectric Power Projects
The Southwestern Power Administration (SWPA), an agency of the Department of Energy, is responsible for marketing the power and energy produced at Federal hydroelectric power projects...

Replacement of Computer Control at John Day Powerhouse
One of the first projects chosen by the Corps of Engineers for computer control was the John Day Project on the Columbia River. John Day powerhouse was completed in 1971 and has 16 generators...

Vibration Problems of Penstock Piping for a Vertical Tubular Hydraulic Turbine
Excessive vibration amplitudes were experienced in the vertical gated tubular units at the Great Falls Hydroelectric Project located in the City of Paterson, New Jersey. Vibration amplitude...

Computer Aided Design of Small Hydro Turbine?Phase II
Ateliers Bouvier have been expanding the use of its computer aided design (CAD) system during these last four years, and the aim of this paper is to present some additional aspects of...

Analysis of Concrete Gravity Dams Using Microcomputers
Monenco Consultants Limited has developed a microcomputer program entitled 'DS2' for the stability analysis of concrete gravity dams. This paper discusses this...

Transient Analysis of the Finchaa Hydroelectric Project
An iterative computer simulation procedure called LIQT (Liquid Transient), which performs simulations of hydraulic transients in closed conduit hydro-power systems, is used to estimate...

Hydropower Analysis Using Electronic Spreadsheets
A sequential streamflow routing procedure is recommended to overcome the inadequacy of the conventional duration curve analysis, especially in cases involving multiple intakes for capturing...

Modeling Sedimentation Problems at Hydro Developments
Sedimentation embodies the processes of erosion, transportation and deposition of sediments. At hydro developments, sedimentation can create problems. Computer sedimentation models (CSM's)...

Recent Developments in Computer Based Control Systems for Hydro Power Control
In recent years microcomputer technology has come to dominate electric control systems. Modern control equipment provides many convenient means for ensuring easy, precise and safe operation...

Visualization of Flow Phenomena in a Hydraulic Turbine Based on 3D Flow Computations
The fluid flow in a Francis turbine has been analysed theoretically. Advanced techniques have been used for both the flow calculation and the presentation of the results in order to clarify...

CAD Speeds Viaduct Replacement
Lack of an available detour around construction of a major viaduct spurred city officials in Reno, Nev. to build a bridge nearby to serve the purpose. Although funded separately, the permanent...

University Programs in Computer-Aided Engineering, Design, and Manufacturing
The University Programs in Computer-Aided Engineering, Design, and Manufacturing (UPCAEDM) annual conferences provide for the presentation and exchange of ideas related to current developments...

From Guesswork to Guarantee?
Maser describes a project to determine the effectiveness of radar and infrared thermography in detecting deterioration of asphalt overlaid bridge decks. The project, sponsored by the New...

Detecting the Defects
According to estimates, for every dollar spent on preventive maintenance of the infrastructure, $10 will be saved by avoiding emergency repairs after major structural failures. Technologies...

SPIDA Method for Reinforced Concrete Pipe Design
The required supporting strength of buried pipe is affected by the total load that is imposed upon the pipe and the manner in which the pipe is supported by the surrounding soil. The installation...

Computing in Civil Engineering
Computers in Engineering Practice
This book contains papers presented at the Sixth Conference on Computing in Civil Engineering held on September 11-13, 1989 in Atlanta, GA. This series, initiated in 1978, provides a continuing...
