Bright Lights Over China
The financing for Guangdong province's newest 700 mw coal fired electric power station came from a syndicate of 46 banks from 11 countries. The steel for the turbine generators...

Ocean Energy: Can It Compete?
Electric power plants using ocean energy are technically viable, but they tend to be cost-prohibitive. A study commissioned by the Electric Power Research Institute and carried out by...

Going Sewerless
An in-building wastewater recycling system is an option where lack of sewers, limits on water supply, and special concerns about water quality are obstacles. The system was incorporated...

Digestor Do-Over
Digesters at 6 Orange County (Calif.) wastewater treatment plants needed drastic odor control rehabilitation. Repairs included epoxy patching to cracked domes, installation of a geomembrane...

Pipe-lining a Pipeline
This core prestressed concrete cylinder pipe is now lining the inside of a major water supply tunnel in Alaska. Occasionally found in rock tunnels, or buried pipelines, large diameter,...

Another Geotech Import: Deep Soil Mixing
A technique called deep soil mixing (DSM), imported from Japan, has been used to stabilize an existing dam foundation. When the Bureau of Reclamation discovered that Jackson Lake Dam had...

Ozoning the Aqueduct
Only the second of its kind in the United States, the Los Angeles Aqueduct Filtration Plant is using ozone to treat drinking water. The water comes from the Sierra Nevadas via the 300...

Supervisory Control System Design
This paper presents supervisory control concepts, elements of a typical system, testing activities, project management, and the procurement process. Modes of control systems are discussed...

Capacity Increase of Multi-Jet Pelton Turbines
The recent connection to the grid of large capacity thermal stations, to meet the increasing demand, has entailed an evolution in the type of services required from storage plants with...

Rock Island District Hydropower
The paper discusses status of hydropower studies within the Rock Island District of the U. S. Army Corps of Engineers. It presents an overview of the low head hydropower studies on those...

Economical Computer Controls for Low Head Hydro
Small power systems based on renewable energy sources such as low head water falls, wind, solar and ocean tides all suffer from stochastic changes in input power. Economically viable,...

Small Scale and Low Head Hydro Development in Canada: An Overview of Federal Activities and Policy
Through research and development, new small turbines have been tested and a Darrieus type vertical axis hydraulic turbine (VAHT) has been developed and field tested. Manuals for hydrologic...

Ruedi Dam Hydropower Project
The Ruedi Dam & Reservoir is owned and operated by the Bureau of Reclamation, U. S. Department of the Interior and is part of the Fryingpan-Arkansas transmountain diversion development....

Lemon Dam Hydropower Project
The Florida Water Conservancy District (District), the entity responsible for the operation of the dam and for repayment of the costs, had been interested in the hydropower potential of...

Small Hydropower Potential in Missouri
The hydropower potential of small head plants on the Gasconade River was investigated. Since, it is felt that small head plants will have less environmental impact, thus it will be more...

Selection of Small Hydro Project Sites
In the course of studying nearly forty areas in Peru to identify possible sites for small hydro development and in order to select the best in each area for detailed design, the Authors...

Evaluation of Small Hydropower Sites in Ghana, Africa
Six potential small sites and one mini site under construction were visited. Two additional potential sites were identified from map studies. Flow duration studies indicated that with...
