When Toxics Meet Metal
Zero-valent iron is an emerging remediation technology that transforms chlorinated solvents to harmless substances. Engineers and researchers have been studying the process for about five...
Cleaning Up Clay
Using soil vapor extraction to remove volatile organic compounds from ground water and unsaturated soils can achieve faster and more-complete cleanups than conventional pump-and-treat...
High Level Radioactive Waste Management 1996
The proceedings of the Seventh International Conference on High Level Radioactive Waste Management, held on April 29-May 3, 1996, Las Vegas, Nevada, continues a concerted effort to transfer...
Estuarine and Coastal Modeling
This volume contains the proceedings of the 4th International Conference on Estuarine and Coastal Modeling held in San Diego, California, October 26-28, 1995. The conference included oral...
River Hydraulics
This manual presents basic principles and technical procedures for analysis of open channel flows in natural river systems. Procedures described herein are considered appropriate and usable...
Mapping History
Difficult, environmentally sensitive terrain combined with the fact that Canadian Western Natural Gas's new Banff pipeline will be laid in archaeologically rich ground posed a challenge...
Grouting Through a River
A regional sewer district in Ohio is implementing a master plan to separate storm and sanitary flows, decommission some old treatment plants and upgrade others. Part of the plan, the West...
Cleanup Solution--Conflict Resolution
Distrust and misinformation often prevent timely resolution of ground-water contamination problems. In Toms River, N.J., engineers used a computer-generated model of the cleanup site in...
Lessons From Kobe
On Jan. 17, Kobe, Japan became the first post-World War II, heavily populated, industrialized area to bear the full brunt of a high-magnitude earthquake. Engineers hope the resulting destruction...
Is Virtual Reality for Real?
Virtual reality, an advanced visualization technology, will change certain aspects of civil engineering. The method allows people to simulate conditions, render designs and test these...

This proceedings,
Hydraulic Design of Flood Control Channels
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 10. This guide presents procedures for the design analysis...
Seismic Design Guide for Natural Gas Distributors
This monograph presents an overview of the sources and geographical distribution of earthquakes, identifies earthquake hazards, and gives the implications of these hazards to gas distribution...
Wider Ride to the Rainbow
Engineers on the project to widen the entrance to the Rainbow Bridge between New York and Ontario let the aesthetics of the Niagara Falls setting dictate their design decisions. The challenge...
Sounding Out Scour
As engineers are aware, detection of bridge scour is the best protection. A method for monitoring scour during low, normal or high water flows would also help alleviate some of the ambiguity...
Doubling A Pipeline
The 36 in. natural gas pipeline built 32 years ago by Pacific Gas and Electric (PG&E) its subsidiary Pacific Gas Transmission (PGT) from Canadian fields to central California has...
Lunar ISRU: An Evolutionary Approach
The goal of this paper is to provide the reader with a vision of the individual steps required to bring ISRU from the current technological readiness level of lab experimentation, to large...
Lunar Oxygen Production - A Maturing Technology
Research on oxygen production from lunar rock and soil has made significant progress in the past two years. An extensive series of experiments on natural and synthetic analogs has concentrated...
Oxygen Generation from Synthetic Moon Soil Using a Plasma Reactor
A series of experiments were performed to evaluate the potential for generating oxygen from silica powder, alumina powder and a synthetic moon soil powder. A non-transferred arc plasma...
Lunar Oxygen Production in a Hydrogen Cold Plasma
This paper examines the concept of oxygen production from unbeneficiated lunar regolith using a non-equilibrium or 'cold' hydrogen plasma. An experimental investigation has indicated that...
