Don't Always Put Dam in Narrowest Part of Valley
Hydraulic factors must be taken into account in dam planning and design, because the best structural design is not always the most economical. When the potential for downstream flood damage...
Value Engineering and Cement-Bentonite Cutoff Wall Save Dam Project for Arizona Indian Tribe
Value engineering showed how it was possible to save $1 million in construction costs for the San Carlos River Dam, east of Phoenix, Ariz. The proposed dam site was moved to take advantage...
Inspecting Dam Construction
Through and competent inspection during construction is crucial to assure dam safty. Inspection for dam construction is more important than for other types of structures because plans...
Tarbela Dam�Problems Solved by Novel Concretes
While constructing the world's largest embankment dam, Tarbela in Pakistan, the designers and contractors faced unprecedented flow volumes and velocities, causing severe cavitation...
Seepage Cutoff Wall Installed Through Dam is Construction First
A new construction technique has been developed which provides a permanent solution to the foundation problems at Wolf Creek Dam. Muddy flows and sinkholes discovered in 1968 led to a...
Highway Embankment Doubles as Dam
By slightly modifying the design of a highway and its drainage, Pennsylvania engineers were able to reclaim about 100 acres of former swampland for residential use. Without extra cost...
Modern Engineering Saves Troubled Dam
A badly deteriorated and potentially unsafe dam has been recycled. The 135-ft-high, 300-ft-long LaPrele Dam is a concrete slab-and-buttress structure. Its sloping face slab has leaked...
Has Metrication Run Out of Gas�
The U.S. is the only major country not to have adopted the International System of Units (SI) as its official measurement system, but the Metric Conversion Act of 1975 established official...
Current Geotechnical Practice in Mine Waste Disposal
Papers Collected by the Committee on Embankment Dams and Slopes of the Geotechnical Engineering Division
The purpose of this volume is to define the current state of geotechnical practice in various aspects of mine waste disposal, an area of increasing interest to the geotechnical engineering...
Current Trends in Design and Construction of Embankment Dams
This report is concerned primarily with the embankment itself although foundation and abutment treatment are considered essential elements of the embankment. It covers a broad range of...
TVA Cuts Deep Slot in Dam, Ends Cracking Problem
In 1972, cracking in the concrete dam at TVA's Fontana project embarked TVA on a four-year program of investigation, analysis and repair. Thermal expansion in the downstream...
$70 Million for Dam Inspection
In 1972, Congress passed the National Dam Inspection Act, requiring the U.S. Corps of Engineers to inspect and inventory all dams in the United States; but few dams were inspected. Then...
Dam Anchored to Foundation to Withstand Floods
Federal Power Commission Order No. 315 required a safety review of Conowingo Dam and Powerhouse by an independent board of consultants. As recommended by this board, a study was made of...
Geotechnical Practice for Disposal of Solid Waste Materials
The papers for this conference are grouped under the themes of four of the general sessions: 1) Geotechnical properties affecting disposal and utilization; 2) utilization in dams, embankments,...
Kamburu Dam: Diversion Conduit Designed into Spillway Saves $1,000,000
