Design and Construction Risk Management for Existing Utilities

Sewer Rehabilitation: Developing Cost-Effective Alternatives

Analysis of Productivity on a Tunnel Operation Using Computer Simulation

Nature's Payback (Available in Geoenvironmental Engineering Special Issue)
Environmental compensation is now a major concern for utilities and other developers who must compensate for impacting wetlands, streams and other environmentally-sensitive areas. To meet...

Rerouting Boston's Utilities
During construction of the Central Artery/Tunnel project in downtown Boston, engineers had to move utility lines over and under both new and existing infrastructure and maintain utility...

Geophysical Exploration for Engineering and Environmental Investigations
The U.S. Army Corps of Engineers has prepared this Manual, Geophysical Exploration for Engineering and Environmental Investigations, to provide an introduction for...

Spawning a Hydroelectric Plant
A hydroelectric facility which utilizes fishway attraction water on the Columbia River between Washington and Oregon will tap a neglected source of power and save many endangered fish...

Financing the Future of Storm Water
For Sarasota County, Fla., draining storm water no longer means draining municipal funds. By establishing a modern storm-water utility, the county has provided a dedicated funding source...

Fracturing for In-situ Bioremediation (Available only in Focus on Geo/Environmental Special Issue)
A pilot-scale evaluation of an integrated pneumatic fracturing and bioremediation system demonstrated the enhanced removal of BTX from a gasoline-contaminated, low-permeability soil formation....

A New Direction in Remediation
Engineers have always had to rely on wells for onsite soil and ground water remediation systems. During the past several years, horizontal drilling technology, adapted from oil recovery...

Hydraulics of Subsurface Flow Constructed Wetlands
Resistance to flow through subsurface flow wetlands is described by Darcy's law or by Ergun's equation. Both representations are combined with the continuity...

An Evaluation of Drainage Conditions in the San Joaquin Valley
The discovery of deformities and deaths of aquatic birds at Kesterson Reservoir in 1983 substantially altered the perception of agricultural subsurface drainage water threats in the San...

Southern San Joaquin Drainage Water Management
This paper addresses management of subsurface saline drainage water in a closed basin in the Southern San Joaquin Valley. A large number of ponds have been constructed to evaporate saline...
