Wind Tunnel Model Studies of Buildings and Structures
This manual provides guidelines on wind tunnel model testing of buildings and structures. Included are procedures required to provide representative information on wind effects experienced...
Shake-Proof Dams
Seismic trouble spots in California and along the Pacific Coast usually get the most publicity. But many people don't realize that Wyoming, Illinois, South Carolina, Utah...
Planning and Designing the Powerplant at Stampede Dam
Power development at Stampede Dam was complicated due to the uncertainty about future reservoir operation and the need to design for seismic risk while attempting to minimize overall cost....
Advances in Controls to Govern Mini and Micro Hydropower Systems
Conventional controls available for small hydropower systems are surveyed. Electronic load controls for micro hydropower systems are described. Recent developments in the literature are...
Installation and Startup of the Idaho Falls Bulb Units
The Idaho Falls Low-Head Hydroelectric Demonstration Project consists of the redevelopment of three existing power plants using identical bulb turbines and generators. This paper summarizes...
Uncertainty Analysis of Field Turbine Performance Measurements
This paper presents comprehensive uncertainty analyses of two different flow measurement methods for field tests on turbines. The 'water to wire' efficiency was...
Francis Turbine Surge Prediction and Prevention
Every Francis turbine has some range(s) of load where the flow in the draft tube is subject to fluctuations. Various types of surge during 'steady-state' operation...
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....
Micro PAT-Synchronous Generator Unit for Isolated Power Supply at Sultan Project Dam
The paper describes a unique application of a micro-PAT Unit installation utilizing downstream release flows for providing an isolated power supply at the Jackson (Sultan) dam in Washington...
Economic factors of Hydro Plants Versus Fossil Plants for Load Frequency Control
The purpose of this study was to determine whether hydro plants with Francis turbines or fossil plants are more economical for load frequency control. Using data from the Tennessee Valley...
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...
Analyses and Field Tests for Hydraulic Transients Sultan Hydroelectric Project
Two in-line Francis units with their long discharge conduit and bypass valves present some unique problems in controlling hydraulic transients in this system. The problems were compounded...
Analysis and Testing of Transient Pressures at Camp Far West Hydroelectric Project
The objective of this paper is to present a comparative discussion of the results of theoretical analysis of transient pressures and of field tests performed on the Camp Far West Hydroelectric...
Evaluation of Liquefaction Potential of Anderson Ranch Dam
This paper contains a description of a liquefaction evaluation of the alluvial foundation soils at Anderson Ranch Dam, which was performed as part of the USBR's program of...
Hoover Dam Earthquakes Reconsidered
In 1936 and 1937 as the water rose behind Hoover Dam, earthquakes were felt in the Boulder City area and as far away as Las Vegas. Interest in induced seismicity was renewed in 1967 with...
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...
Dam Safety Relating to Merwin and Yale Hydroelectric Projects
This paper describes the safety investigations performed to evaluate the dams, associated with the Merwin and Yale Hydroelectric Projects, for the effects of severe floods and earthquakes....
Uprating Hydro Turbines and Generators
Various engineering evaluations of the turbine and generator components are required when considering uprating units. Often, certain turbine and generator components have to be redesigned...
Oxygenation of Releases from Richard B. Russell Dam
In July 1972, the Georgia Department of Natural Resources requested the formation of a technical committee to analyze the water quality matters relating to the Russell project. Studies...
Preventing Fish Mortality at a Large Pumped Storage Plant
A field study program was initiated at the Truman Project to obtain a better understanding of which fish species in the tailrace area would be most susceptible to turbine passage, determine...
