Foreword
The theme of the Twentieth USCOLD Annual Lecture was Dam O&M Issues - The Challenge of the 21st Century. The Lecture was organized by an Ad Hoc USCOLD Joint Sub-Committee on O&M Issues. A number of issues relating to dam operation and maintenance were addressed:
- Operation and Maintenance
- Instrumentation
- Inspection
- Monitoring
- Assessment
- Rehabilitation/Remediation
A total of 51 papers are included in this Proceedings. Authors include specialists with broad experience from water districts, academia, government agencies, utilities and consulting firms.
The Lecture Organizing Committee extends thanks and appreciation to the Host of the Twentieth Annual Meeting and Lecture, Seattle City Light.
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. Note: the 800-page Proceedings are provided in both paper and CD-ROM format.
