Filter Fabrics in Shore-Protection Structures: Save Money, Ease Installation
Over the past decade, plastic filter fabrics have seen growing use in shore-protection structures (e.g. revetments, breakwaters, jetties), river-bank protection schemes, and other areas...

Sand and Gravel � Don't Take Them for Granted
One assumes the supply of sand and gravel is inexhaustible. In fact, at certain times and places it is not. At least not at today's relatively low prices. This is particularly...

Recording River and Reservoir Water Depth
At the Kerr Reservoir on the Roanoke River in Virginia and North Carolina, reservoir bottom was surveyed before reservoir filling and twice thereafter, to determine rate of siltation....

Vibroreplacement and Reinforced Earth Unite to Strengthen a Weak Foundation
Two relatively new engineering concepts in the U.S. were successfully used to solve a difficult soils problem. A highway skirting Idaho's Lake Pend Oreille was built on a...

Minnesota Interceptor Sewer Breaks New Ground
The Beltline Interceptor is a gravity interceptor sanitary sewer which has its outlet in St. Paul and its beginning in White Bear Lake. Major requirements called for a design which would...

Channel Siltation Determined with Side-Scan Radar
Of the new electronic means to measure water depth, side-scan sonar is unusual in that it gives not just a cross-section of the bottom but a semi-3-D picture of the bottom surface. Experienced...

Terrain Analysis for the Trans-Alaska Pipeline
Airphoto interpretation and field reconnaissance were combined with a computer-based data bank to evaluate the diverse terrain conditions along the Trans-Alaska Pipeline because acquisition...

Teton Dam Failure
In June 1976, Teton Dam in Idaho failed. It was an earthfill dam 305 ft high. It failed by piping through the impermeable core of the dam. Among factors believed contributing to failure:...

Liability Claims Against Soils Firms Slashed Dramatically
In 1969, consulting engineering firms engaged on soil and foundation engineering were virtually uninsurable. Taking the bull by the horms, a group of 10 soil and foundation engineering...

Wyoming Grassland May Become World Coal Mining Capital
In the next 10 years United State coal output may double, and forecasts suggest as much as one-third of the increase may come from Campbell County, Wyo. Among topics discussed in this...

Granular-Fill Dam Protected by PVC Membrane
The design and construction of the Minorca Tailings Basin Starter Dam sets a precedent for the use of plastic membrane for seepage control in the construction of earth fill dams where...

Can Trench Cave-In Deaths Be Cut�
About 100 construction workers die each year in trench cave-ins. That toll can be cut, two engineer-researchers conclude. Approach would be to make more-adequate geotechnical analysis...

The Story of Cement, Concrete and Reinforced Concrete
When the dawn of history, man has sought for materials to cement stone and brick together. When rebuilding the Eddystone lighthouse in 1756, John Smeaton recognized ordinary lime morter...

Cost-Effectiveness of On-Site and Community Sewerage Alternatives
Some research and development work has taken place, over many years, on individual on-site treatment and disposal systems as well as non-conventional systems. Most recent work, however,...

Rock Engineering for Foundations & Slopes
Proceedings of a specialty conference on Rock Engineering for Foundations and Slopes, held in University of Colorado, Boulder, Colorado, August 15-18, 1976. Sponsored by the Geotechnical...

Award-Winning ASCE Papers in Geotechnical Engineering 1950-1959
Papers, Discussions, and Closures from ASCE Proceedings and Journal of the Soil Mechanics and Foundations Division
This collection of papers covers a broad range of relevant issues in geotechnical engineering. Topics include capillary phenomena in cohesive soils, final foundation treatment at Hoover...

Yukon River to Prudhoe Bay Highway � Lessons in Arctic Design and Construction
Construction of roads on muskeg over perennially frozen subsoils is becoming increasingly common in the arctic and subarctic regions of North America due to recent emphasis on development...

Let's Consider Land Treatment, Not Land Disposal
The regulations that control operation and design of land treatment systems are discussed. A solution to control ground water pollution must consider all potential impacts. Pretreatment,...

New Orleans Grows on Deep Piles
In the New Orleans area, tall buildings must be supported by piles extending at least into the preconsolidated clays at -150-ft (-46-m) or so. Settlement is much too severe and uneven...

Hydraulic Fill Dams/Earthquake Stability
The 1971 San Fernando earthquake near Los Angeles, Calif., generated concern for the stability of hydraulic fill dams. Two dams located near the fault were damaged severely. The shaking...
