Prediction of Movement in Expansive Clays
The movement of expansive soils is usually due to a change of suction near the soil surface. The properties of the soil that govern the amount and rate of movement are the suction compression...
Test and Prediction Results for Five Spread Footings on Sand
A separate volume summarizes this prediction symposium. It is available from ASCE in New York and is entitled as listed above. This prediction event took place during the conference and...
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...
Measuring the Benefits of Flood Risk Reduction
Property damages avoided, land price analysis, and contingent valuation were techniques used to estimate the economic benefits of flood risk reduction for residential land parcels in Roanoke,...
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 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...
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....
Beneficial Use Alternatives for Water Treatment Plant Residuals
The beneficial use alternatives which are currently in practice for water treatment plant residuals and their relative advantages and disadvantages are summarized in this paper. The alternatives...
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....
Assessing the Reliability of Low Pressure Membrane Systems for Microbial Removal
Low pressure membrane systems are used for microorganisms control in water treatment processes. In this article, the efficiency and reliability of this process is evaluated. Microorganism...
Biodegradation of Phenanthrene in Sand Columns in the Presence of Nonionic Surfactants
The effects of three nonionic surfactants on phenanthrene (C14H10) removal and mineralization by aerobic bacteria...
Quantification of the Mechanisms Controlling the Removal Rate of Volatile Contaminants by Air Sparging
Air sparging is a technology for removing dissolved and volatile phase chemicals (VOCs) from the saturated zone. It is used in conjunction with soil vapor extraction (SVE) and sometimes...
A Probability Based Approach to the Design and Operation of Soil Vapor Extraction Systems
Soil vapor extraction (SVE) or soil venting is related with Monte Carlo simulation of critical soil characteristics. The correlation yielded a probability based nomograph that may be utilized...
In Situ Treatment of VOCs by Recirculation Technologies
Confronted with contaminated land from the world wars and the postwar industrialization period, German researchers and practicing professionals have worked to develop processes for effective...
Effects of Molecular Oxygen and pH on the Adsorption of Aniline to Activated Carbon
This paper examines the influence of molecular oxygen and pH on the adsorption of aniline to F-300 Calgon Carbon. Molecular oxygen increased the adsorptive capacity of GAC for anilines...
Innovative Treatment of Soil Contamination: Radiolytic Destruction of Dioxin and Co-Contaminants by Cobalt-60
Recent work in our laboratory has demonstrated that gamma radiolysis is a feasible method by which 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) can be converted to products of negligible...
Using Drop Structures for Stream Gaging
A long term monitoring program of 15 watersheds, for the purpose of studying channel response to erosion control measures being constructed in north Mississippi, is being conducted by...
Experimental Design and Measurement Techniques for Investigation of Two-Phase Flow
Discussing the relevant hydraulical and inter-phasial processes of two-phase flow in open tanks the necessary requirements for set-up and operation of physical model studies are worked...
