Stress-Deformation Behavior of an Embankment on Boston Blue Clay
An 11 m high I-95 embankment was thoroughly instrumented with piezometers, settlement rods and inclinometers to measure the behavior of the underlying 40 m thick deposit of Boston Blue...
Stress and Settlement of Footings in Sand
In current engineering practice, the magnitude of the settlement of a footing in sand, as compared to the settlement of a different size footing in the same sand, is considered to be a...
Downdrag on Piles: Review and Recent Experimentation
A review of the literature on pile downdrag is provided, within the context of a recent full-scale study involving two pile groups driven in soft clay, subsequently surcharged by a 2.5...
Methods for Risk and Reliability Analysis
Recently, there has been considerable emphasis on the state of decay in the nation's infrastructure because of its importance to society's needs and industrial growth. Water distribution...
Reliability Analysis of Water Distribution Systems
The aging and deterioration of our water supply infrastructure have resulted in performance deficiencies. Limited budgets require that resources for maintenance and rehabilitation be allocated...
Reliability-Based Assessment of Corps Structures
Due to the limited amount of funding available for maintenance, rehabilitation, and replacement of aging Corps structures, the director of civil works, Headquarters, U.S. Army Corps of...
Subjective De-Biasing of Data Sets: A Bayesian Approach
In this paper, we examine the relevance of data sets (for instance, of past incidents) for risk management decisions when there are reasons to believe that all types of incidents have...
Bayes' Theorem and Quantitative Risk Assessment
This paper argues that for a quantitative risk analysis (QRA) to be useful for public and private decisionmaking, and for rallying the support necessary to implement those decisions, it...
Risk-Based Analysis for Flood Damage Reduction
The traditional approach of the U.S. Army Corps of Engineers to flood damage reduction studies is compared to risk-based analysis, a method of performing studies in which uncertainty in...
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...
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...
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...
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...
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...
A Study of Alkalinity Leaching and Residual Strength of Alkaline Stabilized Sludge
The addition of sufficient amounts of quicklime or other alkaline earth oxides to dewatered sludge raises both the pH and temperature of the sludge, resulting in microbial inactivation....
Flocculation Kinetics Using Fe(III) Coagulant to Coagulate Kaolin Clay in Water: Effects of Temperature
Flocculation kinetics using ferric nitrate as a coagulant to coagulate kaolin clay in water was examined using several experimental factors. Both the particle size distribution data obtained...
Recovery of Chromium from Spent Plating Solutions by a Chromyl Chloride Process
A novel chromyl chloride process has been investigated for the recovery of hexavalent chromium from spent plating solutions. In this process chromium is converted to chromyl chloride by...
Modeling of Chemical Inhibition of Nitrification
This work contains two quantitative structure-activity relationships (QSARs) modeling chemical inhibition of nitrification, one for heterocyclic compounds and one for acetylenic materials....
