Foreword
The theme of the 23RD USSD
Conference was Reducing Risk from Extreme Events. The Conference was
organized by the USSD Committee on Hydraulics of Dams, with assistance from the
Committee on Dam Safety and the Committee on Earthquakes.
The Conference addressed
general topics on risk management and evaluation, hydraulics and hydrology and
seismic and geotechnical issues related to risk management. Special emphasis
was placed on remediation for seismic risk in various regions of the country,
including the Southeast.
A total of 54 papers are
included in this Proceedings. Authors include specialists with broad experience
from government agencies, utilities, academia, water districts, consulting
firms and private industry.
The Conference Organizing
Committee extends thanks and appreciation to the Hosts of The 23rd Annual
Meeting and Conference, Duke Power, Santee Cooper and South
Carolina Electric & Gas Co.
Special thanks are also
extended to the Committee Members who selected the abstracts and reviewed the
technical papers, and to the authors who prepared the papers included in this Proceedings.
