Environmental Engineering Research Needs
In June 1979 a National Science Foundation�ASCE workshop was convened to prepare a report suggesting top-priority research needs in civil engineering for the 1980s. The field was split...

Nuclear Testing of Utility Trench Backfill
For many years, Westchester County municipalities were resigned to the fact that compaction of utility trenches could not be done satisfactorily and that settlement and road failure would...

Evaluation and Prediction of Subsidence
Proceedings of the International Conference on Evaluation and Prediction of Subsidence held at Casino Hotel, Pensacola Beach, Florida, January 1978. Sponsored by the American Society of...

Symposium on Earth Reinforcement
Proceedings of the Symposium on Earth Reinforcement, held at the ASCE Annual Convention, Pittsburgh, Pennsylvania, April 27, 1978. Sponsored by the Committee on Placement and Improvement...

Land Treatment Systems and the Environment
This paper summarizes the results from several experiments using the rapid infiltration, overland flow and slow infiltration modes of land treatment....

The Place of Land Treatment of Wastewater in Today's Society
Land treatment of sewage can be a viable alternative to secondary and/or tertiary in-plant treatment. Depending on local conditions, overland-flow, low-rate, or high-rate systems, or a...

Earthquake Engineering and Soil Dynamics
The Conference on Earthquake Engineering and Soil Dynamics is the tenth in a series of Specialty Conferences sponsored by the ASCE Geotechnical Division (formerly the Soil Mechanics and...

Bypassing Sand at Coastal Inlets
To reduce dredging requirements and to provide calm navigation channels, the U.S. Corps of Engineers often constructs jetties and breakwaters. These structures block sand drifting along...

Foundation Soil Preload Saves $164,000
Soils in the lower Mississippi valley are highly compressible and present a challenge to structural foundation designers. Rather than support power plant structures on piles, one design...

Trench Cave-In: Contractor's Responsibility
The article Can Trench Cave-In Deaths Be Cut� in CIVIL ENGINEERING�ASCE, September 1977, states that the owner's engineer should accept responsibility for the design of temporary...

Major Cause of Earthquake Damage is Ground Failure
Ground failure is one of the most destructive effects of large earthquakes. For example, about 60% of the damage during the 1964 Alaska earthquake was a consequence of ground failure....

Design of Excavation Blasts to Prevent Damage
Effects of ground vibrations on nearby structures and people resulting from blasting operations have become a major environmental problem and concern to the engineer and the contractor...

U.K. Tunnelling Costs Halved by Use of Unbolted Concrete Lining Segments
Britain now has more than 25 years experience in the development of precast tunnel linings, for tunnels in clay. These linings are expanded directly against the ground. Under suitable...

Isn't a Subway for Washington, D.C., Just the Thing�
After 100 years of dreaming and 10 years of design and construction, more than 22 miles and 28 stations of the Washington, D.C., Metro are now in revenue operation. When completed in 1983,...

Los Angeles Reservoir is Safe From Earthquakes
The Los Angeles Reservoir was nominated for the 1978 Outstanding Civil Engineering Achievement Award. The reservoir, which replaces the Van Norman Reservoir damaged during the 1971 San...

Land Treatment: An Alternative Technology for Wastewater Management
The 1977 Clean Water Act provides some strong incentives for increasing the use of less costly, less energy intensive technology for municipal wastewater treatment facilities. Specifically,...

Small Midwestern Consultant Introduces Inhouse Desk Top Computer
This article traces the history of engineering and surveying calculations in a small civil-geotechnical consulting office in Rock Island, Ill., W.J. Reese & Associates. The expanding...

Dredge-and-Fill Saves $2 Million at Steel Mill Built in Swamp
The Georgetown Texas Steel Corp., in late 1973, accepted the challenge of developing a previously cleared cypress swamp on the east side of the Neches River across from Beaumont, Texas....

Prefab Structural Components Solve Expansion Problem
Another story was added onto an existing low-rise building, where soil strength was so low that the new floor had to be built by sinking new columns down to a sounder stratum, placing...

Reservoir Outlet Extended Above Silt to Prevent Clogging
Accumulation of silt in an on-stream water storage reservoir almost completely buried the concrete tower originally provided as an outlet intake shaft for releasing stored water through...
