Large dams | SwedCOLD
SwedCOLD is organised as an Executive Committee with representatives from dam owners in the hydropower and mining industry, consultants, contractors, industry organisations and the national dam safety regulator. SwedCOLD connects professionals working with dams and has a network for young professionals. Its main objectives are to provide a national forum for information and discussion, contribute to research and development in dam engineering, and participate in ICOLD’s work. SwedCOLD publishes a newsletter and arranges conferences, workshops and study tours.
ageing portfolio of dams, while the mining industry is continuously raising their dams at tailing management facilities in active operation. There is also a growing commitment from owners, authorities, and investors to contribute to the development and improvement of dam safety and to support sustainable development while balancing different societal interests.

There are approximately 10,000 dams, of which some 1000 facilities include one or more dams that are 5m or higher or have a reservoir volume larger than 100,000m3

hydropower, 40% are embankment dams, 25% are concrete and embankment dams, and 25% are concrete dams. According to the Swedish dam safety regulation, approximately 450 dam facilities belong to a dam safety class, meaning that their failure could result in significant societal consequences or pose a risk to human life. According to ICOLD’s classification, 190 hydropower dams are large, with 80% being embankment dams. These large dams are primarily located in northern Sweden, where the major rivers and the largest mines are situated. Additionally, there are nine active tailing management facilities in Sweden. The challenges the dam industry faces today differ between the hydropower and mining industries. The hydropower industry is faced with managing an
Managing an ageing dam portfolio is a complex and challenging task that requires careful consideration of various technical, economic, environmental, and social factors. As dams continue to age, the risks associated with their operation and maintenance increase, requiring more sophisticated management strategies to ensure their safe and sustainable operation. This is why Management for Safe Dams was chosen as the title for the SwedCOLD symposium during the 91st ICOLD Annual Meeting in Gothenburg from 11-15 June 2023. The symposium covers six themes and their application to various dam types and purposes, including hydropower, flood control, irrigation, levees, and mine tailings. In addition, SwedCOLD has arranged workshops and short courses on current topics, technical excursions to dams in the region, and social events. We hope this Annual meeting will be informative and enjoyable, and we look forward to welcoming you to Gothenburg!
