Hydropower operations in groundwater-influenced rivers: implications for Atlantic salmon, Salmo salar, early life stage development and survival
Casas-Mulet, Roser; Alfredsen, Knut; Brabrand, Åge; Saltveit, Svein Jakob (Journal article; Peer reviewed, 2016)During their early life stages (egg maturation, hatching, alevin development), between late autumn and early spring, young Atlantic salmon are exposed to surface-groundwater interactions in the hyporheic zone and may depend ... -
The impact of hydropeaking on juvenile brown trout (Salmo trutta) in a Norwegian regulated river
Saltveit, Svein Jakob; Brabrand, Åge; Juarez, Ana; Stickler, Morten; Dønnum, Bjørn Otto (Peer reviewed; Journal article, 2020)The Norwegian electrical energy supply system is based on hydropower. The now deregulated energy market has led to increased use of hydropeaking production, leading to greater fluctuations in discharge and water levels ... -
Survival of eggs of Atlantic salmon (Salmo salar) in a drawdown zone of a regulated river influenced by groundwater
Casas-Mulet, Roser; Alfredsen, Knut; Brabrand, Åge; Saltveit, Svein Jakob (Journal article; Peer reviewed, 2015)Groundwater may create refuges for Atlantic salmon egg survival during low flows in regulated rivers and thus play an important role for survival during winter. To investigate the links between the survival of salmon embryos ... -
Testing and evaluation of a HYMO classification system for lakes and reservoirs - Proposed new and modified hydromorphological (HYMO) classification system
Bakken, Tor Haakon; Beck, Valerie; Schönfelder, Lennart Hagen; Charmasson, Julie; Thrane, Jan-Erik; Lindholm, Markus; Brabrand, Åge (SINTEF Rapport;, Research report, 2019)This project has tested and evaluated a hydromorphological (HYMO) classification system for lakes and reservoirs, published in 2018. The results revealed that applying the full set of parameters require extensive resources, ...
