Frazil Ice Control Using Air Guns
The design of the J. H. Campbell, Unit 3, Cooling Water Intake in the late 1970's used some new ideas and concepts in response to a strong concern for fish protection at a...

Laboratory Studies for the J. H. Campbell, Unit No. 3, Cooling Water Intake Design
A three-year study sponsored by the Empire State Electric Energy Research Corporation was conducted to determine the overall efficiency of a full-scale angled screen demonstration facility...

Yakima Remote Control System: Supervisory Control and Data Acquisition
The Yakima Remote Control System is a computerized supervisory control and data acquisition (SCADA) system developed for the operation of the Bureau of Reclamation's Yakima Project in...

Response of Floating Structures in a Directional Sea
A finite element numerical model is presented to predict the behavior of long floating structures in a multi-directional sea. A follow up numerical model analyzes an important but mostly...

Hydro Power Intake Design?Criteria and Experience
This paper briefly addresses parameters to be considered in hydro power intake designs. Included are design approaches and criteria, specific examples, and applicable references. Concerns...

Intakes for Low Head Hydro Plants
The design of hydro intakes is usually based on a desire to achieve low intake losses and an acceptable approach flow distribution to the turbine. Generally, velocities in the intake canal...

Fish Diversion in Hydropower Intake
Hydraulic model studies were conducted to develop a fish screening system to be used in the turbine intakes of Priest Rapids Development on the Columbia River, Washington. The system studied...

Water Supply Intake Structures on Western Rivers
Many of the problems experienced with water supply intake structures on western rivers result from a failure to mitigate the effects of moving sediments. Shallow but varying flow depths...

Vortices at Vertical Intakes
This paper presents the results of an experimental investigation designed to predict the formation of weak, free-surface vortices at vertical intakes with a headrace channel. A weak vortex...

Embankment Overtopping
Embankment overtopping and dam safety are major concerns of civil engineering and the general public. Very little is known about overtopping events and much less has been published or...

Computer Techniques for Acquisition and Reduction of Cross-Section Data
DuPage County, Illinois, has initiated a county-wide stormwater management program for planning and flood mitigation purposes. Field data with horizontal and vertical control are obtained...

Microprocessor-Based Data Acquisition Systems
The application of microprocessor-based data acquisition systems to laboratory experiments and field tests is discussed. The importance of the system design and hardware selection is emphasized....

Analytic Solution for Seepage from Saturated Soil Behind a Braced Wall
The locations of streamlines and equipotentials for two-dimensional flow in the vertical plane normal to a vertical retaining wall can be determined by various methods. Recent extension...

Centrifugal Abrasion-Resistant Pumps in Intermediate Length Pipeline Systems
The success of long-distance slurry pipelines is in many cases dependent on careful preparation of the solids prior to transport. Positive displacement pumps are employed. However, for...

Series Finished Water Pumping Facilities
The paper discusses studies and design of series finished water pumping facilities for the Potomac River Water Treatment Facilities. Detailed hydraulic studies were conducted which concluded...

Cazenovia Creek Model Data Acquisition System
The purpose of the model is to reproduce river ice breakup phenomena for optimizing the design of an ice control structure. The performance of the ice control structure during a simulated...

APM Configuration Concepts and Network Design
The simpler networks, along with several of the more complex variations, include the following: Single-Lane Shuttle, Single-Lane Shuttle with Bypass, Double-Lane Shuttle, Single-Lane Loop,...

Investigation of Design Criteria for APM Guideways
Designers have relied mostly on the provisions of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway Bridges. Sometimes...

Design Criteria Impacts on Guideway Development
A highly definitive design criteria or performance specification is frequently developed for new transit systems. The criteria are intended to protect the owner's interest...

A Unique Communication System for Aerial Ropeways
The basic principles of operation of a Double Reversible Aerial Tramway are introduced. A brief note is given explaining a safety circuit or survey current used on the haul rope, since...
