Draghead Designs vs. Production
This paper discusses the development and design of draghead configurations for silt materials and describes a testing program designed to determine the most efficient range of the controllable...
Acoustic Silt Density Measurement
Significant savings can be achieved on the costs of operations for the deepening and maintenance of navigation channels and harbor basins in muddy areas provided that computations are...
Influence of Roughness on Velocity and Dispersion at Low Flow
Dependence of the hydraulic and transport characteristics of low flow on channel roughness is investigated. Empirical expressions are used to estimate roughness coefficient as a function...
Flow Parameters of Fluid Mud
A set of small-scale, high-resolution velocity and stress sensors based on rugged metal-clad hot wires and epoxy-encapsulated hot films is to be evaluated for its performance characteristics...
Coping with High and Low Pressures of Transient Flow
Conditions exist in most long distance water pipelines, such that abnormal but inevitable occurrences will cause transient flow. Often the most crucial conditions for consideration by...
Milwaukee Sewerage District Interplant Pipeline
The pipeline is intended to transfer solids between the Jones Island and South Shore treatment works a distance of approximately 12 miles (19. 3 km). The 4 conduit pipeline comprising...
Riprap Sizing-Four Methods
A comparison summary is provided for sizing of riprap by four methods: Isbash, Froude, Tractive Force - Logarithmic Velocity Profile (TFL), and Tractive Force - Power Velocity Profile...
Cavitation in Various Types of Shear Flow
Cavitation in turbulent shear flow depends on the intensity and spectral characteristics of the pressure fluctuations in a Lagrangian frame of reference as well as depending on the concentration...
Modeling of a Multifunctional Hydraulic Structure
A 1:12 scale Froude model of a hydraulic control structure in the Rochester Combined Sewer Overflow Abatement Program (RCSOAP) was constructed and tested to optimize the design requirements...
Streamflow Measurement and Analysis for Northwest Rangelands
Watershed hydrologic and sedimentation investigations on the Reynolds Creek Experimental Watershed in southwest Idaho were initiated in 1960. Major objectives of the watershed research...
Field Flow Measurement of Hydro-Turbine Efficiency
Performance tests were conducted at Great Northern Paper (GNP) Company's Weldon Hydroelectric Station. The purpose of the tests was to calibrate the Winter-Kennedy taps and...
Power from a Water Supply System: A Resource Which Can Be Tapped
There are numerous water supply systems from which hydroelectric power could be developed without impending the regular operational schedule. The basic principle of operation is not different...
Hydraulic Research--U.S. Geological Survey
Research at the Gulf Coast Hydroscience Center near Bay St. Louis, Mississippi, is being conducted in an indoor laboratory, and an outdoor laboratory. Much of the current indoor lab research...
Design and Operation of Pipeline Control Systems
More and more of the time of the engineer involved in the design and construction of a pipeline project is devoted to problems relating to the control systems to operate and monitor the...
Electronic Traffic Management
High technology has entered the world of traffic and transportation management with such new optical and electronic devices as transponders, retro-reflective stickers, microprocessors,...
The Third Wave in Water Quality Management
In the 1970's there was great pressure to clean up water-polluting discharges no matter what the cost. Now in the tight-budget 1980s, there is a vigorous search for more cost-effective...
Directional Wave Spectra Applications
These collected papers and their ensuing discussions presented at the September, 1981 symposium at the University of California on directional wave spectra applications examine the present...
San Francisco Convention Center Goes Underground
The Moscone Convention Center, built at a construction cost of �126 million, opened its doors to an admiring public on December 2, 1981. The Center's grand exhibit hall, 90...
