Frost action processes in the Eastern Suorva hydropower dam
The hydropower embankment dam in Suorva, Sweden, is located in north of the Arctic Circle. The region is known for cold winters and severe wind conditions. The construction was completed in 1972 and has since then been exposed to a wide temperature range and low annual mean temperatures, leading to...

The region is known for cold winters and severe wind conditions.
