100 key questions to guide hydropeaking research
Hayes, Daniel; Bruno, Maria Cristina; Alp, Maria; Boavida, Isabel; Batalla, Ramon J.; Bejarano, Maria Dolores; Noack, Markus; Vanzo, Davide; Casas-Mulet, Roser; Vericat, Damia; Carolli, Mauro; Tonolla, Diego; Halleraker, Jo Halvard; Gosselin, Marie-Pierre; Chiogna, Gabriele; Zolezzi, Guido; Venus, Terese E. (Peer reviewed; Journal article, 2023)As the share of renewable energy grows worldwide, flexible energy production from peak-operating hydropower and the phenomenon of hydropeaking have received increasing attention. In this study, we collected open research ... -
A cost-effective approach to predict dynamic variation of mesohabitats at the river scale in Norwegian systems
Casas-Mulet, Roser; Alfredsen, Knut; Garcia-Escudero, Ana (Journal article; Peer reviewed, 2014)This paper presents a cost-effective approach to predict dynamic variation of mesohabitat classes or hydromorphological units (HMUs) in the context of a peaking scenario. Predicting dynamic mesohabitats has been a challenge ... -
Dynamics of Dewatering and Flooding during Hydropeaking
Casas-Mulet, Roser (Doktoravhandlinger ved NTNU, 1503-8181; 2014:79, Doctoral thesis, 2014)Hydropeaking in rivers is likely to become more frequent in a context of increasing demand for renewable energy due to the storage potential of hydropower systems. Increased peaking operation in hydropower plants will lead ... -
Early careers on ecohydraulics: challenges, opportunities and future directions
Wilkes, Martin A.; Neverman, Andrew J.; Casas-Mulet, Roser; Adeva Bustos, Ana; McCluskey, Alexander H.; Ouellet, Valerie; Vanzo, Davide; Franklin, Paul A.; Silva, Ana T. (Journal article; Peer reviewed, 2016)Early career researchers (ECRs) play a critical role in our knowledge-based society, yet they are the most vulnerable group in the scientific community. As a young, interdisciplinary science, ecohydraulics is particularly ... -
Hydrological and thermal effects of hydropeaking on early life stages of salmonids: A modelling approach for implementing mitigation strategies
Casas-Mulet, Roser; Saltveit, Svein Jakob; Alfredsen, Knut (Journal article; Peer reviewed, 2016)Alterations in hydrological and thermal regimes can potentially affect salmonid early life stages development and survival. The dewatering of salmon spawning redds due to hydropeaking can lead to mortality in early life ... -
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 ... -
Introducing HyPeak: An international network on hydropeaking research, practice, and policy
Alp, Maria; Batalla, Ramon J.; Bejarano, Maria Dolores; Boavida, Isabel; Carpa, Hervé; Carolli, Mauro; Casas-Mulet, Roser; Costa, Maria; Halleraker, Jo Halvard; Hauer, Christoph; Hayes, Daniel; Harby, Atle; Noack, Markus; Palau, A.; Schneider, Matthias; Schönfelder, Lennart Hagen; Tonolla, Diego; Vanzo, Davide; Venus, Terese E.; Vericat, Damia; Zolezzi, Guido; Bruno, Maria Cristina (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 ... -
Modelling of environmental flow options for optimal Atlantic salmon, Salmo salar, embryo survival during hydropeaking
Casas-Mulet, Roser; Alfredsen, Knut; Killingtveit, Ånund (Journal article; Peer reviewed, 2014)Recent findings on the causes of Atlantic salmon embryo mortality during winter in a hydropeaking river suggest that long duration drawdowns during very cold periods are the most likely cause of mortality in the ramping ... -
Performance of a one-dimensional hydraulic model for the calculation of stranding areas in hydropeaking rivers
Casas-Mulet, Roser; Alfredsen, Knut; Boissy, Thibault; Sundt, Håkon; Rüther, Nils (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. ... -
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 ... -
The effects of hydropeaking on hyporheic interactions based on field experiments
Casas-Mulet, Roser; Alfredsen, Knut; Hamududu, Byman Hikanyona; Timalsina, Netra Prasad (Journal article; Peer reviewed, 2015)Hydropeaking power production has the potential to pose serious challenges towards hydrology, water quality and ecology in the downstream water bodies. The effects of such abrupt changes of flow in hyporheic exchange have ... -
