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...
Mixed Layer Modelling of Stratification in Lakes
Mathematical models for vertical heat transfer processes in lakes and reservoirs are grouped into two classes: diffusion models and mixed layer models. In recent years much of the progress...
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...
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...
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...
Guidelines for Transmission Line Structural Loading
Procedures are provided for the selection of design loads and load factors based on the latest research and state-of-the-art design techniques. This selection has an effort on the reliability...
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...
Design of Port and Coastal Structures for Ice Forces
Design of ice-affected port and coastal structures cannot be addressed in a few single specific terms, but must instead account for a matrix of elements differing at each site. Evaluation...
Bibliography on Ocean Energy
With the prospect of an increasing shortage of energy resources, there has been a growing interest in renewable alternative sources of energy. An increasing effort is being directed towards...
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...
