Flutter Derivatives from 14 Generic Deck Sections
The results of a series of wind-tunnel bridge-deck section-model experiments are discussed. Fourteen section models, seven with H-shaped cross-sections and seven with rectangular cross-sections,...
Application of the New SCS Time of Concentration Method
The second edition of the Soil Conservation Service (SCS) TR-55, published in June 1986, introduces a new method for calculating the time of concentration for storm runoff flowing through...
Time-Domain Dam-Reservoir-Interaction Analysis Based on Boundary Elements
For a reservoir with an arbitrary shape of the upstream face and of the bottom including an adjacent regular part of constant depth extending to infinity, the hydrodynamic-stiffness matrix...
Milan's Model Metro
A number of innovative geotechnical methods were used at the extension of the Milan, Italy, subway. Jet grouting, a technique used only a few times in the United States, was notable among...
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...
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...
Criteria for Selecting Turbine-Pumps Used in Mini-Hydro Power Units
The present paper is aimed at studying turbine-pump units operating at low heads. The proposed methodology is based on the global matching of the turbine and the pump so that both will...
A Marine Thruster in Small Scale Hydropower
A 70 kW hydroelectric plant utilizing a marine thruster as a turbine was commissioned in May, 1985. The thruster, the construction management, the site conditions and the testing program...
Development of Two Plants on California Canals
The projects utilize the head drop between canals on the system of the Central California Irrigation District (CCID. ) The projects utilize the elevation difference between the District's...
Low Head Hydroelectric Development on Madera Canal
The Madera-Chowchilla Power Authority with cooperation from the U. S. Bureau of Reclamation has been successful in the development of four hydroelectric plants at five head drops on the...
Two New Machines for Ultra Low-Head Hydropower
This paper outlines the development of two new types of positive displacement ultra low-head hydropower machines, the AUR Water Engine (AURWE) and the Salford Transverse Oscillator (STO)....
Crooke's Falls Small Hydro: A Case History
The paper discusses the background, financing, licensing and other aspects of hydroelectric power plant development at Crooke's Falls, Colorado....
Case Study?Wyre Wynd Hydroelectric Project
To combat rising energy costs, Southwire Company, a manufacturer of wire and cable products headquartered in Carrollton, Georgia, began generating its own electrical power at the company's...
Operation of the Annapolis Tidal Straflo Unit
The Annapolis Tidal Generating Station, located at Annapolis Royal, Nova Scotia, is the first plant in North America to generate electricity by Tidal action. The facility, rated at 19....
A New Turgo Turbine in China
In this paper a special runner bucket of the new Turgo turbine is illustrated and a comparison is made between the characteristics of the new Turgo and the ordinary Turgo turbine with...
Rim-Drive Turbine for Low Head Applications
A turbine design and testing program was undertaken with the objective of developing a standardized turbine/generator arrangement that would be well suited to the 10 to 30 foot head range....
Economic Analysis of Low Head Hydropower Projects
A typical low head hydropower project is described and used as an example of the effect of tailwater on power generation. The discharge characteristics of upstream facilities, pool regulation...
Laser-2-Focus Flow Measurements in the Runner of a Bulb Turbine and Comparison with Calculation
Flow measurements are presented, which were carried out near and inside the 4-blade runner of an axial model bulb turbine of double adjustable type. These measurements were performed by...
