Dam Safety Interest Group
Many of the dams around the world were designed and built over 35 years ago. As these structures age, the level of safety becomes more difficult to evaluate, particularly where original design details are not known. Moreover, safety and design standards have changed over the years and many of these aging structures must be upgraded to meet current standards. Research is required for the development and evaluation of new diagnostic monitoring tools and techniques for the assessment of the stability and safety of existing dams. New repair materials and techniques can reduce the cost of required dam safety
improvements.
The Dam Safety Interest Group (DSIG) is composed of dam owners who jointly sponsor research & development projects designed to help assess and improve the safety of dams. Today, the DSIG is represented internationally by participants from Canada, the United States, Australia, Sweden, France, the United Kingdom, and Germany.
Topics and Issues:
• Risk assessment for dam safety
• The use of geophysical methods in the diagnostics and monitoring of embankment dams
• Erosion and piping in dams
• Reliability of discharge facilities
• Ice loadings
• Probability (frequency) of extreme floods
• Emergency preparedness
• Testing of embedded dam anchors |

Mr. Constantine G. Tjoumas provides insight accumulated over more than 25 years with the Federal Energy Regulatory Commission (FERC). He most recently held the position of Director, Division of Dam Safety and Inspections with FERC, overseeing the establishment, maintenance, and review of policies, procedures, and standards for the inspection and supervision of more than 1,700 licensed hydroelectric projects comprising 2,600 dams across the United States. This included supervising the work of a highly specialized staff of engineers and geologists engaged in activities related to the construction and the operation and maintenance of projects, and the establishment of a continually evolving dam safety and dam security inspection program. He is a Member of the American Society of Civil Engineers and formerly served as Chairman of the Committee on Dam Safety and Dam Security with USCOLD (now the USSD) and is currently the Vice Chairman of the ICOLD Committee on Dam Safety. |
