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...

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,...
Impacts of Risk-Based Analysis on Current Design Practices
A summary of hydrologic design standards used by selected federal agencies for the safety evaluation of dams is presented. A computational procedure is outlined to develop hydrologic design...
The Use of ISMAUT in Determining the Most-Preferred Package of Alternatives
Multiattribute decision analysis serves as a useful model of alternative selection under risk. A specialized form of multiattribute decision analysis assumes that there is only one stage...
A Methodology for Risk-Benefit Analysis of Lock-and-Dam Rehabilitation in the U.S. Corps of Engineers
The U. S. Army Corps Engineers operates and manages some 250 locks and dams in major rivers and ports throughout the U. S. At present, many of these structures are thirty-five to forty-five...
