Movement of Nonaqueous Liquids in Groundwater
Evidence from field sites indicates that when nonaqueous liquids, such as organic solvents and gasoline, are released into the subsurface environment they tend to remain as a separate...

Analysis of Plastic Soil in Contact with Cavitose Bedrock
A numerical analysis has been conducted to evaluate the stress deformational response of highly plastic soils in contact with cavitose Bedrock. The numerical idealization represents the...

Hazardous Waste Landfill Cap System Stability
Pursuant to the regulatory requirements for control of rainfall infiltration into a hazardous waste landfill, a cap design that is impervious plus stable is required. The intent of a cap...

Automated Permit Review for Hazardous Waste Surface Impoundments
The United States Environmental Protection Agency has proposed to develop automated permit review for RCRA hazardous waste surface impoundment facilities. The review automation will consist...

Thickened Slurry Disposal Method for Process Tailings
Common practice in the disposal of process tailings consists of impounding the wastes as thin slurries or suspensions in diked containment areas. Such a procedure poses problems relating...

Modelling of Contaminant Transport in Clays Via Irreversible Thermodynamics
This study develops a model for the analysis and prediction of contaminant transport in soils using principles of irreversible thermodynamics. The developed model includes five parameters...

Structural Engineering and Microcomputers
This publication contains five papers on the use of microcomputers by structural engineers. The first paper discusses the design of multi-story rigid steel frames. The design process employed...

Seismic Analysis of Safety-Related Nuclear Structures and Commentary on Standard for Seismic Analysis of Safety Related Nuclear Structures
This standard provides requirements for performing analyses to obtain design information which will lead to the reliability of structures under a severe earthquake. The goal of this standard...

Use of Vibration Measurements in Structural Evaluation
Over the past decade the capabilities for vibration measurements and analysis have advanced significantly. It is now a routine procedure to be able to measure natural frequencies of structures...

Temporary Structures in Construction Operations
Temporary works have a primary influence on the quality, safety, speed and profitability of all construction projects. They provide access, support and protection of a facility under construction....

Dynamic Response of Pile Foundations?Experiment, Analysis and Observation
In recent years, a considerable amount of attention has been paid to the dynamic response behavior of pile foundations. However, mainly because of difficulties in conducting tests and/or...

The Mexico Earthquakes?1985
Factors Involved and Lessons Learned
This publication reports initial results of study of the 1985 Mexico earthquake, one year after the event. The findings present sufficient depth of analysis to provide an understanding...

Investigating Failure
Failure investigations can be adversarial or cooperative, but impartiality, good engineering ethics, and professional responsibility require that the investigator begin with no premature...

Predicting Equipment Failure
At Cleveland's Westerly Water Pollution Control Center, the physical/chemical plant for treating wastewater is one of the largest of its kind, with 50 mgd average capacity....

Expert Systems for Risk Analysis
An explanation is presented on why construction risk analysis can be handled by an expert system computer program. The author offers a prototype construction risk management expert system...

Building Frame Analysis in Basic
Moment distribution has, for the past 30 years, been the most popular method of analysis for statically indeterminate structures. Programmed in Basic for the microcomputer with relative...

Aids for the Hazard Classification of Small Dams
The last few years have seen a large growth in the tools available to the engineer to better determine the risk of failure in earth dams. One of the models developed is the National Weather...

An Uncertainty Analysis Methodology Applied to Sheetpile Cofferdam Design
The input data to numerical simulation models is often uncertain, and, consequently, model predictions may be uncertain. Such uncertainties are often treated by Monte Carlo techniques....

A Stratified Mixing Channel: Theory and Experiment
The performance of a deep and stratified mixing channel is assessed theoretically and experimentally. The channel has a rectangular cross-section, a negligible longitudinal slope and is...

A Comparison of Tidal Sediment Boundary Layer Profiles with Theory
A number of theoretical derivations have been presented for predictions of the sediment concentration profile near or at the bottom of a column of surface water. Ultrasonic transceivers...
