Southern California Edison Company.
The Meeting was held on July 22-26, 1996, at the Hotel
Inter-Continental, Los Angeles, California.
Lecture
The theme of the Sixteenth USCOLD Annual Lecture was Seismic
Design and Performance of Dams. The Lecture was organized by
the USCOLD Committee on Earthquakes to address such topics as
Seismic Parameters and Seismic Analysis Techniques for Dam
Design; Seismic Design of Earthfill, Rockfill and Concrete Dams;
Foundation Considerations; Seismic Design of Appurtenant
Structures; Reservoir Triggered Seismicity; Seismic
Instrumentation; Seismic Upgrades of Deficient Dams; and Case
Histories.
In all, 19 Lecture papers and 5 Poster Session papers were
presented. The Annual Meeting Proceedings include the Lecture and
Poster Session papers; copies are available for purchase from USCOLD for
$25 (USCOLD members), $40 (nonmembers) and $44 (foreign
