Selecting an Economical Water Main Rehab
Many miles of aging water mains exist with carrying capacities that are less than half of what they were when new. Engineers must, therefore, stretch every dollar to eliminate deposits...

Dredging Developments in the Canadian Arctic
The use of dredges in the Canadian Arctic in connection with oil exploration programmes has lead to the adaptation of existing and adoption of new techniques. Further development is required...

Placing of Impermeable Underwater Membranes
An impermeable underwater membrane has been applied successfully in the construction of a lowered road section in the Netherlands. In this paper the construction technique is discussed...

Settlement and Stability of Ocean Disposal Mounds
This study examines the engineering behavior of dredged material disposal mounds in Long Island Sound. The study area is located about eight miles off the coast of New Haven where several...

An Offshore Mound Constructed of Dredged Material
The concept of using dredged material to intentionally construct an underwater mound was tested and confirmed at the Dam Neck Disposal Site, 4 miles offshore Virginia Beach, Virginia....

Hydraulic Testing of a Large Make-Up Pipeline
A 37 mile pipeline which consists of sections of 114 inch, 96 inch and 66 inch pipes was constructed for delivering secondary sewage effluents for power plant makeup. During initial operations,...

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...

Hydraulic Analysis of Water Transmission Flowing Party Full
The hydraulic behavior of a transmission line that flows full along only part of its length is more difficult to analyze than a completely full line. Unsteady open-channel and closed-conduit...

Computer Aided Hydraulic Design of Pipelines
General purpose computer software packages are being used more frequently in the hydraulic design of pipeline systems. The areas where the use of such packages are advantageous over earlier...

Vacuum Assisted Pipelines Operation
In the process of upgrading the sewerage facilities for Lancaster, Pennsylvania, it was decided to combine two existing facilities into one new facility. This required the design of three...

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...

Pipe Spillway Plunge Pool Design Equations
An equation is given to determine if scour holes will beach and widen excessively. For nonbeaching scour holes, dimensionless equations are given for the progression of scour with time...

A Quantitative Assessment of Surface Water Resources for Coal Slurry Pipelines Originating in Southwest Virginia
In view of the high streamflow variability, preliminary quantitative assessment was made of the capacity requirements and low-flow frequency characteristics of offstream reservoirs needed...

Hydropower Plant on an Irrigation Pipeline
A 940-kW hydroelectric plant was installed on a renovated irrigation pipeline at a Bishop, California ranch. On its way to the ranch, the falling water now generates an average of 4. 2...

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...

Will Southern California Revert to a Desert?
The nearly 13 million people in Southern California - one-half of California's population - face the prospect of water shortages in the near future. These people depend on...

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...

Structural Engineering in Nuclear Facilities
The papers in this publication cover the general theme of civil and structural engineering as they are applied to nuclear facilities. Traditional topics include seismic analysis, impactive...

Guidelines for the Seismic Design of Oil and Gas Pipeline Systems
Current knowledge on the practice of earthquake engineering for oil and gas pipeline systems is presented. Such systems typically consist of buried oil, gas, or product pipelines and aboveground...

Ports 83
The Ports '83 Specialty Conference, whose theme is Modernization, Upgrading and Repairs, covers considerations in port operations, design and construction due to obsolescence...
