Prototype Experience With Acoustic Flowmeters
The acoustic (ultrasonic) flowmeter offers many advantages over other methods for measuring discharge in penstocks for turbine performance tests. It is nonintrusive, inexpensive and may...
Hydro Machinery Problem Solving Experiences
Within the last decade the use of modern data acquisition instrumentation and techniques have moved the subject of the machinery problem solving into a more scientific arena. This paper...

This paper describes the pumping and generating units and associated electrical equipment planned for Waddell Pumped-Storage Plant. Waddell Pumped-Storage Plant is to be located near Phoenix,...
Control and Tests of Tims Ford Induction Generator
This paper will discuss the electrical control scheme and commissioning tests developed for a small induction generator installed by the Tennessee Valley Authority (TVA) at its Tims Ford...
The Stanley Canyon Conduit Hydroelectric Project
The Stanley Canyon Hydroelectric Project is an excellent example of the maximum use of a natural resource. The project is a combined water supply and hydroelectric facility which received...
Upper Yellow River Projects and Longyangxia Station
The river stretch from Longyangxia to Qingtongxia, with a head drop of 1,465 m in a distance of 1,023 km (including backwater length of the Longyangxia Reservoir) is the focus of this...
Summer Falls High Head Kaplan Turbine Project
The Summer Falls Project is located on the Main Canal of the Grand Coulee Irrigation Project approximately eight miles south of Coulee City in Grant County, Washington. The power development...
Our Municipal Water System Has Power
Hydroelectric potential exists in the Boulder, Colorado municipal water system. Excess pressure is developed in the water system because the water originates in the Rocky Mountains, west...
Hydropower Goes Downtown
Beneath a busy street in Southern California seems an unlikely location for a small hydroelectric generating plant. However, located just below El Segundo Boulevard in the town of El Segundo...
Planning, Design and Cost Estimates for RCC Dams
Engineers, planners, and officials of agencies responsible for developing water resource projects are confronted with preparing preliminary designs and cost estimates for dams. This paper...
Design of Seepage Control Systems for RCC Dams
As the reservoirs of the first generation of roller compacted concrete (RCC) dams have been filled, several have exhibited significant amounts of seepage, a fact that has been of concern...
Roller Compacted Concrete Mix Design for Pamo Dam
Pamo Dam is designed as a 265 foot (81M) high gravity dam that will be located on the Santa Isabel Creek in San Diego County, California. RCC volume will be approximately 491,000 cubic...
Quality Control/Inspection�Upper Stillwater Dam
Roller compacted concrete construction, or RCC, is a relatively new method of constructing concrete dams and involves placing and spreading no-slump concrete in horizontal layers and compacting...
Regulatory and Environmental Issues of the Chisman Creek Superfund Site
This paper discusses the regulatory and environmental issues arising from the response to the Record of Decision (ROD) for the Chisman Creek Superfund Site in York County, Virginia. Field...
Evaluation of Air Quality Methods in the Asbestos Work Area
Air monitoring is a technique that is routinely used to measure the level of asbestos in a given airspace. This technique has changed significantly since its first use in the asbestos...
Professional Liability on Asbestos Abatement Projects
When the engineer is retained on an asbestos abatement project, he or she must bring to the job and employ that degree of skill and learning ordinarily exercised in the profession in similar...
Random Vibration of a Discrete-Distributed System
The stationary response of an arbitrarily complex, classically damped discrete-distributed system subjected to stationary Gaussian white noise is derived. For certain excitations, the...
Characteristics of Nonstationary Response of Linear Systems
A new formulation for the statistics of the response of linear systems to nonstationary excitation is developed. Both the process and its envelope are examined and exact statistics are...
Effect of Air Gap on Platform Reliability
A simplified reliability study of the effect of lateral wave forces impacting the deck of a fixed platform is presented. The reliability of the deck legs, considered the primary resistance...
Expert Systems for Drought Management: A Case Study
This paper describes the development and application of a computer model used by the Seattle Water Department (SWD) for operations during drought. This model provides guidance for initiating...
