Computer-Assisted Problem Solving in Hydraulic Engineering
A number of practical hydraulic problems may be solved using software that allows interaction at the equation level rather than through higher level languages. This paper presents examples....
Microcomputers in Hydraulics-Hydrology Education
Microcomputer software is utilized for pipe network analysis, unsteady flow in pipelines, watershed modeling, flood studies, reservoir operations, dam break analysis, and groundwater systems...
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...
Transients in Empty Pipes Subject to Rapid Filling
A mathematical model was developed to simulate the pipe filling process and the pipe forces based on incompressible water column theory. The method easily accomodates appropriate boundary...
Quick Stroking: A Fast and Accurate Algorithm for Time-Optimal Valve Closure Synthesis
In this paper, a fast, simple, yet effective technique for valve motion synthesis is developed. This technique called Quick Stroking is applied to a practical example problem, and it may...
Girth Weld Defect Tolerance Criteria
This paper describes the following criteria proposed for setting allowable defect sizes in girth welds: PD 6493:1980, 'Guidance on Some Methods for the Derivation of Acceptance...
Solutions in the Pipeline
Water and sewer agencies across the country are beginning to feel more comfortable about pipeline rehabilitation. Where once replacement was the ony alternative considered for aged, clogged...
Updating the New York City Water System
The New York City Bureau of Water Supply maintains extensive records of all water main breaks dating back at least as far as 1940. A computerized file of the main break records was prepared...
Advances in Underground Pipeline Engineering
The field of underground pipeline engineering has undergone a rapid growth during the last two decades. The analysis, design, construction, operation, and maintenance of underground pipelines...
Tampa Does It with Mirrors
As one of the nation's fastest growing cities, Tampa needed far more public works dollars. But the traditional source, the real estate tax, can no longer be relied on so heavily,...
Retrofitting Lifeline Facilities: The Japanese Approach
A brief history of the prediction of a major earthquake in the Tokai Area of Japan is reviewed. Planning and mitigation incorporating all levels of government and the private sector is...
Performance of Water and Sewer Lifelines in the May 2, 1983 Coalinga, California Earthquake
Water supply and filtration systems for the City of Coalinga suffered little damage. The water transmission system suffered five breaks. The urban distribution system was disrupted, but...
Ocean Energy
The Ocean Thermal Energy Conversion (OTEC) component nominated this year as an ASCE Outstanding Civil Engineering Achievement involves the most critical design problem; the cold water...
Update on Impact Effects in Nuclear Plants Part II?Review of Pipe Whip Impact
Current regulations require that pipe breaks be postulated in high-energy lines and measures be taken to prevent consequent damage to essential structures and systems. The paper addressed...
Slurry Pipeline Control Systems
The paper documents the La Perla-Hercules pipeline and its control system. This eight and fourteen-inch, 382-kilometer iron ore concentrate slurry pipeline was commissioned in June of...
Allen-McColloch Pipeline Computer Based Control System
The Allen McColloch Pipeline (AMP) was designed to deliver 416 cfs of treated water from the Metropolitan Water District of Southern California's Diemer Water Treatment Plant...
Automatic Controls for Industrial Water System
An 8-mile pipeline and associated facilities along its route are controlled by a centralized system consisting of a master station and four remotes. Each site employs Westinghouse programmable...
Security of Unattended Pipeline Stations
The ultimate purpose of a security system is to maintain equipment and service in a normal operating condition or to restore the equipment and service to normal operating condition as...
Pipeline Hydraulic Transient and Leak Detection Analysis
Liquid and gas pipelines cannot be properly designed with consideration of steady flow analysis techniques alone due to the possibility of pipeline failure resulting from uncontrolled...
Design and Performance of Buried Fiberglass Pipes ? A New Perspective
The buried performance of fiberglass pipes was the subject of a comprehensive and multifaceted research program carried out in 1982 and 1983. Instrumentation, capable of accurately tracing...
