A Conflict between Traditional Flood Measures and Maintaining River Ecosystems? A Case Study Based Upon the River Lærdal, Norway
Juarez, Ana; Alfredsen, Knut; Stickler, Morten; Adeva Bustos, Ana; Suarez, Rodrigo; Seguin Garcia, Sonia; Hansen, Bendik Kristoffer Torp (Peer reviewed; Journal article, 2021)Floods are among the most damaging of natural disasters, and flood events are expected to increase in magnitude and frequency with the effects of climate change and changes in land use. As a consequence, much focus has ... -
Hydropower‐driven thermal changes, biological responses and mitigating measures in northern river systems
Heggenes, Jan; Stickler, Morten; Alfredsen, Knut; Brittain, John Edward; Adeva Bustos, Ana; Huusko, Ari (Peer reviewed; Journal article, 2021)Water temperatures control life histories and diversity of aquatic species. Hydropower regulation, particularly in high head systems, alters natural water temperature regimes, which may have profound and long‐term impacts ... -
Identification of salmon population bottlenecks from low flows in a hydro-regulated river
Adeva Bustos, Ana; Hedger, Richard David; Fjeldstad, Hans-Petter; Stickler, Morten; Alfredsen, Knut (Journal article; Peer reviewed, 2019)Flow regime alterations from hydropower regulation may impact fish populations. Impacts can be characterized using methods for mapping bottlenecks for different species life stages. Improving the understanding of such ... -
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 ...
