Supply Side Engineering
In New Jersey, the Hackensack Water Co., a private utility, and the North Jersey District Water Supply Commission, a state agency, are jointly completing Wanaque South, a $151 million...

Instant Hydro Forecasting
Two new software programs developed by a San Francisco-based engineering firm determine hydropower potential, best site configuration, and best economics for hydroelectric projects. One...

Alternate Sewers�No Longer Alternate
The term alternate sewers means those used where neither conventional gravity sanitary sewers will suffice, nor will the septic tank/leach field system. In such situations, usually one...

Seismic Interaction Among Numerous Masses Founded on a Viscoelastic Stratum
The steady-state harmonic response of systems comprising numerous masses resting on a homogeneous, viscoelastic stratum with hysteretic damping is studied. The stratum, bearing on a rigid...

Explosive Loading of Surface Ships
This paper describes the recent development of numerical methods which have accurately predicted the response of surface ships subjected to underwater explosion tests. The technique couples...

Water Project Design and Safety: Prospects for Use of Risk Analysis in Public Sector Organizations
After offering some initial definitions, the authors will describe a highly structured model of risk analysis and water resources decision making in the public sector. The primary emphasis...

Approaches to Acceptable Risk
Acceptable risk has numerous meanings, that are derived from its having been defined in multiple arenas and by multiple groups. This paper describes several approaches to the question...

The Credibility of Probabilities: An Application to Water Resources Policy
This paper focuses on one particularly troublesome issue in decision analysis, the issue of the credibility of subjective probabilities. A water resources policy problem is used to illustrate...

The Sociocultural Context of Coping with Risk and Uncertainty
In the context of the present conference, selected points will be underscored about the centrality of risk and uncertainty in contemporary society, aspects of judgment and decision making,...

A System Framework for Engineering Risk Analysis
A mathematical system framework is developed to model a series of criteria called performance indices (PI) related to engineering risk in water resources. Such criteria include reliability,...

The Status of Risk Analysis in Water Resources Engineering
Acceptance of probabilistically based risk-analysis evaluation methods among water resources engineers is rather slow, as it is among other engineering specialities. Academic researchers...

The Risk Factor in Water Resources
Risk is inherent in nature and society, while uncertainty depends on investigations. Decision making in water resources is most often a deterministic selection of dimensions which divide...

U.S. Bureau of Reclamation Use of Risk Analysis
The United States Bureau of Reclamation (USBR) has been using risk analysis techniques in assessments for management decisions. Before presenting USBR practice and experience, the paper...

Some Perspectives and Philosophies on Risk-Based Decision Making in Water Resources
The authors have selected four perspectives of the water resources decision problem that illustrate how formal risk-based approaches may be applied - an economic perspective, an environmental...

Environmental Considerations in Risk-Based Decision Making in Water Resources
In the hypothetical Royal River Project there are several factors pertaining to environmental issies; these factors have a bearing on selection among the several alternatives and lead,...

The Ultimate High Tide
Unprecedented consumption of fossil fuels and clearing of vegetation have spurred interest in the greenhouse effect. Under this scenario, a build-up of carbon dioxide and other gases in...

Behavior of Concrete Bulkheads in Salt Drifts
Parameters studies of the behavior of a plug made from expansive concrete have been performed. Such plugs are now being field tested for sealing boreholes, shafts and drifts at an underground...

The Basics of Water-Resistant Brick Walls
Water-resistant masonry walls of burned clay or shale brick are the result of a conscious effort to produce them, by everyone involved in their creation. Furthermore, owner maintenance...

Pipeline Frost Heave Predictions Using a 2-D Thermal Model
Chilled structures founded on initially unfrozen soils cause a zone or 'bulb' of frost to develop with time. This time period may be of seasonal duration, as...

Structural Design of the Defense Waste Processing Facility
The Defense Waste Processing Facility (DWPF) is designed to process radioactive defense waste sludge and the radioactive nuclides, cesium and stronium, from the salt solution. These radioactive...
