Olmos Dam Modifications
(1981 OCEA Nominee.) The 55-year-old Olmos Dam, five and one-half miles northeast of San Antonio, Texas, required major modifications to avoid...

Recent Development in Geotechnical Engineering for Hydro Projects
Eleven of the papers presented at three sessions of the ASCE Geotechnical Engineering Division at the 1981 International Convention are included. The papers are divided into two subjects:...

Why Bother with Historic Preservation�
Two case histories are examined regarding old dams that were preserved because of their historic importance, as well as their practical use. One example concerns a dam that was exposed...

Rehab or Replace? Foundation Testing Provides the Answer
A $15 million, multidisciplinary testing program was undertaken to determine the least expensive methods of rehabilitating Locks and Dam No. 26 on the Mississippi River. The Problems were...

Geotechnical Research Needs
A National Science Foundation-ASCE workshop on research needs looked at, among other subfields, geotechnical engineering. The study identified a number of research needs�based on society's...

The New Energy Boom: Hydropower
Based on the U.S. Army Corps of Engineers estimate, there are 49,500 dams in the U.S. that could produce around 9,000 MW of power. The government has been subsidizing demonstration projects...

Research Needs in Hydraulics, Coastal Engineering and Irrigation
Last June an ASCE/NSF team gathered at Warrenton, Va., to prioritize research needs in civil engineering. They split the field into 10 subcategories, one of which is Hydraulics, Coastal...

TVA's Pumped Storage Plant
TVA's Raccoon Mountain Plant is one of the U.S.'s largest with generating capacity of 1530 MW for 20 hours. The project, nominated for a 1980 OCEA, consists of...

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...
