The Expert Video Series - Ground Improvements for Dam Safety

This two-tape set is the latest addition to the video series produced by the Federal Interagency Committee on Dam Safety (ICODS), the Federal Emergency Management Agency (FEMA), and the U.S. Bureau of Reclamation (USBR). The tapes are suitable for viewing by dam safety professionals, water project owners and managers, regulators, students and the public.

Tape 1, Methods, Applications, Selection and Design (51 minutes), examines the types of dam safety projects and problems that might be addressed by in-situ ground improvements. The methods of deep densification, grouting, mixing, and drainage are described in detail, with an explanation of how they work and how they are evaluated. Also addressed are considerations in the selection and design of a suitable method.

Tape 2, Case Histories and Lessons Learned (56 minutes), illustrates the application of different ground improvement methods at three projects: Nigeria's Jebba Hydroelectric Development, Jackson Lake Dam, Wyoming, and the Mormon Island Auxiliary Dam, near Sacramento California. These case histories show what was done at the site of a major new dam, the replacement of an existing dam following its removal and foundation improvements, and ground improvement required to improve seismic stability of an embankment and its foundation.
