Main Canal Headworks Hydroelectric Project
This project is being installed at the Dry Falls Dam, Coulee City, Washington, adjacent to the Main Canal Headworks which controls the irrigation releases to the Columbia Basin Project....

The Paerau Gorge Multipurpose Scheme
The Paerau Gorge Power Scheme is part of a multipurpose scheme supplying irrigation water and electricity to the Central Otago region of the South Island of New Zealand. This paper describes...

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...

The PowerBarge?Portable Hydro for the Third World
The PowerBarge concept consists of a floating intake, siphon penstock, and floating generating station for use at new or existing low-head dams. Apart from access, mooring facilities,...

Optimization of Low Head Hydro Equipment
In this paper, we will limit our purpose to the presentation of the different types of turbines that CE/Neyrpic proposes for low head power plants, for run of the river operations. We...

Small Kaplan Versus Tubular and Francis Turbines
Mossefossen Power Plant is situated in the centre of the small town Moss in the southern part of Norway. Water flows from an existing dam through a 9 m**2, 175m long tunnel to the powerhouse...

Design Criteria for Generators in Low-Head Hydro-Power Plants
Principal characteristics and design features of such generators are discussed and options and preferences in their selection mentioned. Effects on inertia constant, efficiency, reactive...

Index Testing?Relative Turbine Performance
The Index method of testing hydraulic turbines consists of making a test in which the value of power output and head are measured and in which the quantities of water and velocity head...

The Design, Analysis and Manufacturing of Pickwick Landing Replacement Runners
This paper presents new computer automated techniques for the design, analysis and manufacture of Kaplan turbine blades. The inlet flow field was determined using the finite element program...

Design and Manufacture of Turbine Runner Blades Using CAD/CAM-Technology
Interactive blade design, fluid flow analysis, stress analysis and NC-matching of both model and prototype blades are working from a common data base and are demonstrated in this paper....

Computerized Engineering for the Hydraulic Design of Hydro-Turbine Stay Vanes
To design a turbine stay vane as an integral part of the spiral case/stay vane/wicket gate waterpassage, both the vane geometry and the gate/vane position must be developed and analyzed....

Advance Prediction of Flow-Induced Variations
Frequency analysis of hydraulic vibrations has been applied using a transfer matrix and impedance method. The computer program is given for the self-excited and forced vibrations, together...

Open Flume Turbine Intake Geometry
An inexpensive physical hydraulic model was used to investigate the geometry of two different open flume turbine intakes. One intake utilized an inverted, fabricated pump bell type of...

Diffuser Performance for Draft Tube Applications
Available information on diffuser performance is summarized in relation to draft tube applications. This paper is particularly directed at the implications of basic research with these...

Hydraulic Machines Model Acceptance Tests
The article begins with a description of the modern test installations, giving the dimensions of the models most frequently used and the head heights. Attention is then given to the most...

Arch Dams for Small Hydroelectric Sites
Approximate formulas are developed for the design of small arch dams. These designs, although conservative, frequently allow for economies over other dam types. Considered are: an approximate...

Control System Design Considerations for Small Hydro Projects
This paper deals with the philosophy that must be embraced when specifying a fast track small hydro project. The major areas discussed are: the role of control systems in the context of...

Changing Stability Criteria: Effect on Older Dams
Many of the dams on the Georgia Power Company system were designed and constructed in the early 1900's. Changes that have occurred in stability criteria since construction...

Dynamic Analysis of Existing Tarbela Intake Towers
According to general practice at the time of the design, the pseudostatic method of applying earthquake loading was used. The basic acceleration was 0. 1g. A post-construction seismological...
