Seminar on Safety Evaluation of Existing Dams
Because the often-catastrophic consequences of dam failure are unacceptable, the need for trained personnel is essential. This seminar provides attendees with comprehensive instruction in dam safety examination and evaluation. Although references will be made to organizational procedures and units of Reclamation, the principles, concepts, and procedures are readily adaptable to any organization conducting a regulatory or in-house dam safety program for existing dams.
The basic seminar emphasizes the importance of dam safety and provides information and instruction in dam safety surveillance, including periodic review of pertinent records, visual examination, and monitoring of instrumentation. Hydrologic considerations, concrete repair, remedial measures for dams, and emergency action planning are also discussed. The seminar is suitable for engineers, technicians, maintenance personnel, and administrators responsible for dams.
The seminar includes a visit to a local Colorado dam to practice inspection techniques during a simulated dam examination.
As part of the seminar, three concurrent workshops are being presented on Thursday afternoon to provide more information on the following subject areas:
- Engineering Geology and Dam Safety Workshop presents an introduction to geologic investigation and evaluation relative to dam safety static and seismic issues.
- Evaluation and Response to Seepage and Internal Erosion Concerns presents seepage process and failure modes, types of sinkhole formations, and approaches for investigating and responding to seepage and internal erosion conditions.
- Emergency Management presents key elements of a dam owner's responsibilities regarding facility operations in response to emergencies, namely detection, decision making, and notification and how to exercise those responsibilities through simulated events.
The seminar instructors will consist of a group of professional engineers and geologists who have a great deal of experience and knowledge in the areas of design, construction, operation, maintenance, instrumentation, and dam safety evaluation. Many of the instructors have conducted training programs for Reclamation and other US and foreign personnel involved in dam safety.
Free. Reclamation's Dam Safety Office is providing the seminar at no cost to attendees. However, due to agency restrictions, the audience is limited to Federal agency, Tribal and Reclamation Water District personnel. Interested States, local Governments and private sector staff, please visit the Association of State Dam Safety Officials website for dam safety training alternatives.
Participants will receive a seminar notebook (not available separately) and some additional material to supplement the lectures. Limited numbers of the “Safety Evaluation of Existing Dams Manual”; and the book, "Dams and Public Safety," will be available. It is suggested that you leave space in your luggage for these books or bring your method of payment and shipping label and the hotel will mail your books to your home office for you.
