Flood Loss Assessment with Integrated Measures
In most cases, the maximum flood loss reduction can be achieved only by an optimal combination of both structural and nonstructural measures. An integrative approach that combines the...
Risk-Based Budgeting for Maintenance Dredging
The U.S. Army Corps of Engineers must estimate the budget required to conduct maintenance dredging at hundreds of sites across the country. The amount of funds needed to do the maintenance...
Developments in Risk Analysis Commercial Software
There has been a marked increase in the number and type of commercial software packages available to support risk and uncertainty analysis. Monte Carlo simulations, the first such tool,...
Uncertainty versus Computer Response Time
Interactive on-line presentation of risk analysis results with immediate `what if' capability is now possible with available microcomputer technology. This can provide an effective means...
Risk Simulation Model for Rehabilitation Studies
The U.S. Army Corps of Engineers is required to analyze major rehabilitation proposals for all facilities using risk-based benefit-cost analysis techniques. Existing spreadsheet-based...
Environment-Irrigation Trade-Offs and Risks
Allocation of scarce water resources between environmental and commercial uses is an extremely important problem in many parts of the world. A study is under way in Australia to examine...
Climate Warming and Great Lakes Management
A decision-analysis approach to determining the relevance of information on climate change for near-term Great Lakes management decisions is outlined. Simplified applications to decisions...
Coastal Eutrophication and Temperature Variation
A 3-D hydroecological model has been developed to simulate the impact of climate-change-induced daily temperature variation on coastal water quality and eutrophication. Historical daily...
Federal Risk Management Policy: Where Is the Federal Government Heading? Where Are the Problems?
The paper summarizes the first session of the conference which discussed the present state and problems of federal risk management policy. Topics discussed include efficacy of models on...
Risk and Reliability of Water Resources Infrastructure and Engineering Approaches to Risk and Reliability Analysis
The paper summarizes the second session of the conference which discussed the risk and reliability of water resources infrastructure as well as engineering approaches to risk and reliability...
Behavioral, Social, and Institutional Aspects of Risk Analysis
The paper summarizes the third session of the conference which discussed four items that become pitfalls for decision makers when neglected. These are parameter uncertainties as distinct...
Risk Management Strategies for Natural, Manmade, and Technological Hazards
The paper summarizes the fourth session of the conference which discussed risk assessment approaches in bio/chemical hazards; specific studies on people's behavior and views of natural...
Risk Management Strategies for Natural, Manmade, and Technological Hazards
The sixth session featured three important applications of risk and reliability analysis in water resources planning. Papers were presented on incentives to use reliability and risk analysis...
Computer Software for Risk Analysis
The seventh session was directed toward computer software that is designed for use in various aspects of risk analysis. The papers presented discussed the following: application of user-friendly...
Climate Change
The wide range of predictions from global climate models most often encourages a wait-and-see approach. These uncertainties and a trust that conventional policy is sufficient to accommodate...
Controlling Lead and Copper Corrosion and Sequestering of Iron and Manganese
With the recently enacted Lead and Copper Rule (LCR), many utilities are faced with the conflict of meeting the requirements of the Rule and controlling aesthetic problems caused by source...
Modeling Issues of Copper Solubility in Drinking Water
The paper discusses the application of a model to the solubility of copper in drinking water. This paper is the result of numerous forms of pitting corrosion and pipe failures. Monitoring...
The Effects of NOM and Coagulation on Copper Corrosion
Copper corrosion was examined in solutions containing natural organic matter (NOM) and in situations where NOM was removed by enhanced coagulation with alum or ferric chloride. Electrochemical...
Water Chemistry of Lead Corrosion Control
Requirements of the Lead and Copper Rule (U.S. EPA) makes it necessary for regulators, consultants, and water purveyors to understand the fundamental relationships between water quality...
Cryptosporidium and the Milwaukee Incident
In early 1993, Milwaukee, Wisconsin reported a sharp increase in the number of diarrhea patients and shortage of over the counter drugs for diarrhea control at local pharmacies. This increase...
