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...
Do-Nothing Cleanups
Restoring polluted soil and ground water to pristine condition is, in some cases, neither cost-effective nor feasible. So what's the best way to close these sites with minimal...
Pump and Treat and Wait (Available only in the Geo/Environmental Special Issue)
Pump and treat, a common ground-water cleanup technique, is slow to clean up deep contaminated aquifers. Adaptive intermittent pumping can increase the cleanup rate�and decrease costs�by...
Non-Aqueous Phase Liquids (NAPLs) in Subsurface Environment
Assessment and Remediation
The growing number of incidents of soil and groundwater contamination with non-aqueous phase liquids (NAPLs) has caught the nation unprepared. A number of challenges confronted the three...
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...
Greening of Ground Water
As many as 69 different organic compounds and 24 metal species can be found in ground water underlying the 85 acre Bofors-Nobel Superfund site in Muskegon County, Mich., a testimony to...
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...

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...
Beyond Water Witching
Ground-water exploration is usually an uncertain and expensive endeavor. Since late 1993, however, Golder Associates Inc., Redmond, Wash., has been working with time-domain electromagnetics...
Artificial Recharge of Ground Water II
The Second International Symposium on Artificial Recharge of Ground Water was held in Orlando, Florida from July 17-22, 1995 and sponsored by the ASCE Special Standards Division, the ASCE...

Mother Nature's Pump and Treat
Known under the general term of phytoremediation, using vegetation as a remedial agent has existed in its basic form for many years, mostly in applications involving waste-water treatment....
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...

Geo-Environmental Issues Facing the Americas
Contamination of soil and ground water are problems common to developed as well as developing countries; their effects on health and the deterioration of natural resources transcend national...
Freeway through a Superfund Site
The Red Mountain Freeway is the centerpiece of a 171 km $2.6 billion system of freeways and expressways under construction in Maricopa County, Ariz. For 3 km in Tempe, the freeway passes...
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...
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...
