By-pass valves in hydropower plants: An ecologically important measure to mitigate stranding in rivers due to emergency turbine flow shutdown
(Journal article; Peer reviewed, 2023)Hydropeaking operations or accidental shutdown in hydropower (HP) plants lead to rapid reduction in river flows downstream HP outlets and cause severe stranding of biota. Stranding of fish in dewatered riverbeds is a major ... -
Classification of hydropeaking impacts on Atlantic salmon populations in regulated rivers
(Peer reviewed; Journal article, 2021)This article proposes and demonstrates a new classification system of fish population level effects of hydropeaking operations in rivers. The classification of impacts is developed along two axes; first, the hydromorphological ... -
Development of an inflow-controlled environmental flow regime for a Norwegian river
(Journal article, 2012)Hydropower produces 99% of the electricity in Norway, and a large number of rivers are regulated. Currently, static minimum flow regimes are used as a mitigation measure for most of these developments, usually having fixed ... -
Effect of flow ramping on stranding potential related to river morphology—Developing hydraulic indices for peaking severity
(Peer reviewed; Journal article, 2023)Stranding can be an important negative effect downstream of peaking power plants. Much work is put into computing indices of peaking operation based on flow data from power plant outlets or in reaches downstream of power ... -
Hydropower‐driven thermal changes, biological responses and mitigating measures in northern river systems
(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 ... -
Introducing HyPeak: An international network on hydropeaking research, practice, and policy
(Peer reviewed; Journal article, 2022)An increase in the demand for renewable energy is driving hydropower development and its integration with variable renewable energy sources. When hydropower is produced flexibly from hydropower plants, it causes rapid and ... -
Performance of a one-dimensional hydraulic model for the calculation of stranding areas in hydropeaking rivers
(Journal article; Peer reviewed, 2014)Fish stranding is a critical issue in rivers with peaking operations. The ability to accurately predict potential stranding areas can become a decisive factor to assess environmental impacts and to plan mitigation measures. ... -
Regional Statistical and Precipitation–Runoff Modelling for Ecological Applications: Prediction of Hourly Streamflow in Regulated Rivers and Ungauged Basins
(Journal article; Peer reviewed, 2017)Prediction of natural streamflow in regulated rivers for derivation of ecologically relevant streamflow metrics (ERSFMs) and prediction in ungauged basins (PUB) are important in management of water resources. However, ... -
The Survival of Atlantic Salmon (Salmo salar) Eggs During Dewatering in a River Subjected to Hydropeaking
(Journal article; Peer reviewed, 2015)Hydropeaking in regulated rivers is likely to become more frequent with increasing demands for renewable energy. Sudden fluctuations affect surface and subsurface flow regimes and change hydrological interactions occurring ... -
Towards an automatic characterization of riverscape development by deep learning
(Peer reviewed; Journal article, 2021)Riverscapes are under pressure from anthropogenic development, and this challengesthe conservation of biodiversity, hydromorphology and land types. To assess changesand restoration potential, an understanding of alteration ...
