Foreword
The theme of the Nineteenth USCOLD Annual Lecture was Dealing with Aging Dams. The Lecture was organized by the USCOLD Committee on Hydraulics of Dams, with the support of the Committee on Dam Safety and the Committee on Construction and Rehabilitation. A variety of issues relating to aging dams were addressed:
- Mechanical and Electrical Aspects
- Dam Safety Programs
- Instrumentation and Monitoring
- Geotechnical Aspects
- Managing Dam Rehabilitation and Associated Risks
- More Aging Dam Concerns
- Case Studies - RCC Applications
A total of 38 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 Committees extend thanks and appreciation to the Host of the Nineteenth Annual Meeting and Lecture, The Southern Company.
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.
