Foreword
The theme of the 26th USSD Conference was The Role of Dams in the 21st Century. The Conference technical program was organized by several USSD Committees under the leadership of John W. France, URS Corporation.
The technical program focused on a broad range of topics that relate to applications of current engineering technologies for dams and their roles in today's society. Dam engineers, owners and operators shared and discussed new and innovative technologies in engineering, construction, monitoring, operating, safety, risk management and decommissioning. Proven technologies for embankment dams, concrete dams, spillways, environmental enhancement, project delivery, dam security, hydraulics, hydrology, instrumentation, and seismic and geotechnical issues were discussed.
A total of 49 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 Host of the 26th Annual Meeting and Conference, the San Antonio River Authority.
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.
