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...
Perspectives on Modelling Consolidation of Dredged Materials
The physical and mathematical aspects of this problem are highly nonlinear and material-property relationships extend beyond the scope of standard geotechnical engineering. The potential...
High Streamflow Behaviors in the Ohio River Basin
The intensity function, which describes the severity of the flood occurrences, is a critical factor in flood control and reservoir operation. It is found that the occurrence rates of high...
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...
Decision Making in Establishing Instream Flow Needs in Minnesota
Allocation of water for instream use depends upon how well the need and justification for instream flows can be communicated to decision makers. The analysis and presentation of instream...
Mackenzie River Breakup: Ft. Simpson to Ft. Good Hope, N. W. T.
Breakup progression on the Mackenzie River in 1982 and 1983 is described. Two types of breakup, and two types of ice jam formation associated with these, were identified. The major role...
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...
Boston Tunes Up Water System
In 1977, Boston's water supply system had so many leaks and so many unmetered or undermetered customers that only about half the water entering the system was accounted for....
Water Supply
In 1982, the Washington Metropolitan Area took steps to optimize its water supply for the next 50 years or more. Using state-of-the-art water resource management techniques, the local...
Design of Offshore Pipelines for Ice Environments
Design and installation of offshore pipelines in cold regions requires special care. Low ambient temperatures may cause increased friction losses in oil and gas lines due to wax crystallization...
In Third World Villages, a Simple Handpump Saves Lives
Millions die each year and many more suffer in the developing countries from diseases spread by contaminated water. In fact, it is estimated that 80% of all disease in the world is due...
Chemical Spill Cleanup Named Project of the Year
A 1978 hazardous-waste spill in Michigan has been cleaned up so successfully that the American Consulting Engineers Council named it the 1982 project of the year. Here is how the railroad...
If Your City's Well Water Has Chemical Pollutants, Then What�
Synthetic organic chemicals, especially certain solvents, are showing up in groundwater all over the U.S. and in many other industrial countries as well. These substances, some of which...
Transportation Innovations that Would Banish America's Energy Crisis
Despite the current oil glut, the energy crisis is still very much with us. Within the next few decades, the U.S. will nearly exhaust economically recoverable petroleum. The key to solving...
Solar Energy for Heating Homes: How Practical�
There is a widespread belief that on-site solar energy for heating homes is still not a proven technology and that, in any event, it's much too expensive. The fact is that...
Birth of the Synthetic Fuels Industry
The U.S. is now in the early stages of creating a synthetic fuels industry, a much needed step to help to decrease America's dependence on foreign oil imports. Synfuels refer...
Ports '80
Papers from twenty-three sessions of the speciality conference on energy ports and terminals are presented. The theme of the conference was Energy, Ports, Perspective, and considerations...
Making Maps by Computer�City and Utilities Team Up in Pioneer Effort
There is heavy duplication of map making and maintenance�as many as 68 different maps of the same area were counted in the Vancouver, Canada, suburb of Burnaby. This, and the fact that...
Regulations: More is Less
Federal regulations have mushroomed since 1969. Agencies to write and enforce regulations have grown as well. Now, say engineers in industry, it is increasingly not economically feasible...
Systems of Waste Water Management in Europe
The history of European waste water management is briefly reviewed. Legal aspects of waste water management are presented by examples from Germany and Switzerland. International agreements...
