One of our reference cases

Sädva Dam

A Rockfill Dam in Northern Sweden

Seepage Evaluation from Resistivity Monitoring


The Sädva dam is located in the upper part of the Skellefteälven River just south of the Arctic Circle. It has a reservoir storage volume of 625 million m3. The dam and power plant was put into operation in 1985. The total length of the dam is 620m, which is divided in a 210m long main dam across the old river channel and a 410m long dyke along the old river channel. The maximum height of the main dam is 32m. The dam is a rock fill embankment dam with a slightly inclined central core made of fine-grained glacial till.
