The Sima is a river in the municipality of Eidfjord in Hordaland, Norway.[1] [2] The river is 29.64km (18.42miles) long, and it has a drainage basin of 125km2[1] and an average discharge of 8.86m3/s.[3]
The river has its source on the west side of the Hardanger Glacier, at a proglacial lake called Demmevatn at an elevation of 1290m (4,230feet).[1] The river then flows west from Lake Rembesdal (Rembesdalsvatn), with an elevation of 905m (2,969feet), into the deep Sima Valley and past the former 272m (892feet) high Rembesdal Falls (Rembesdalsfossen), which is now dry because of hydroelectric plant infrastructure.[4] In the Sima Valley the river is joined by the Skytjedal River (Skytjedalselva), a left tributary known for Skytjefossen, a 300m (1,000feet) high waterfall.[5] The river continues west until its mouth at the head of the Simadal Fjord.
Together with the nearby Bjoreio River to the south, the Sima River has been developed for power production at the Sima Hydroelectric Power Station.[2] The power station is located in the mountains below Kjeåsen on the north side of the Simadal Fjord.
