Before the GA in the end of June we participated in a field excursion.
Our first stop, after an amazing boat ride, was at NTNU’s Sletvik biological field station where we learned about their teaching/research in the bay of Hopavågen with special hydrological features due to its narrow inlet from the sea. Read more about Sletvik here.
Our second stop was at Follsjoe Dam, operated by Statkraft. We learned about new construction work being carried out to bolster the dam according to new regulations. Dams in Norway are reviewed every 15 years and checked for compliance with current regulations. This dam is special due to the chosen method for bolstering the dam (riprap), which is human-placed rock material to protect the dam against erosional processes. Check out the cool pictures below!
Downstream of the dam, a hydraulic structure has been added to prevent wild salmon from entering the river, to control for parasitic infestation.
Our last stop was to see a sediment trapping basin, reducing sedimentation of the reservoir located further downstream. At the photos below you can see basin.
Stay tuned for a post from the GA!
