Application of Three-Dimensional CFD Model to Determination of the Capacity of Existing Tyrolean Intake
Bor Turkben, Asli; Szabo-Meszaros, Marcell; Vereide, Kaspar Vatland; Lia, Leif (Peer reviewed; Journal article, 2024)CFD models of intakes in high-head hydropower systems are rare due to the lack of geometric data and cost of modeling. This study tests two different types of software to see how modeling can be performed in a cost-effective ... -
Can Energy Depletion of Wild Atlantic Salmon Kelts Negotiating Hydropower Facilities Lead to Reduced Survival?
Baktoft, Henrik; Gjelland, Karl Øystein; Szabo-Meszaros, Marcell; Silva, Ana T.; Riha, Milan; Økland, Finn; Alfredsen, Knut; Forseth, Torbjørn (Peer reviewed; Journal article, 2020)Repeat spawners constitute an important component of Atlantic salmon populations, but survival of post-spawning individuals (kelts) are often compromised by anthropogenic structures such as hydropower plants (HPPs). Potential ... -
Digitalization and real-time control to mitigate environmental impacts along rivers: Focus on artificial barriers, hydropower systems and European priorities
Quaranta, Emanuele; Bejarano, Maria Dolores; Comoglio, Claudio; Fuentes-Pérez, Juan Francisco; Perez-Diaz, Juan I.; Sanz-Ronda, Francisco Javier; Schletterer, Martin; Szabo-Meszaros, Marcell; Tuhtan, Jeffrey (Peer reviewed; Journal article, 2023)Hydropower globally represents the main source of renewable energy, and provides several benefits, e.g., water storage and flexibility; on the other hand, it may cause significant impacts on the environment. Hence sustainable ... -
Experimental hydraulics on fish-friendly trash-racks: an ecological approach
Szabo-Meszaros, Marcell; Navaratnam, Christy Ushanth; Aberle, Jochen; Silva, Ana T.; Forseth, Torbjørn; Calles, Olle; Fjeldstad, Hans-Petter; Alfredsen, Knut (Journal article; Peer reviewed, 2018) -
Supersaturation in hydropower installations
Vilberg, Ingrid; Szabo-Meszaros, Marcell; Pulg, Ulrich; Velle, Gaute (Research report, 2023)Gas supersaturation occurs when the amount of dissolved gas in water exceeds the solubility for the given local pressure. Such conditions may happen in natural watercourses, but more observations are associated with ... -

Validation of a Swimming Direction Model for the Downstream Migration of Atlantic Salmon Smolts
Szabo-Meszaros, Marcell; Silva, Ana T.; Bærum, Kim Magnus; Baktoft, Henrik; Alfredsen, Knut; Hedger, Richard David; Økland, Finn; Gjelland, Karl Øystein; Fjeldstad, Hans-Petter; Calles, Olle; Forseth, Torbjørn (Peer reviewed; Journal article, 2021)Fish swimming performance is strongly influenced by flow hydrodynamics, but little is known about the relation between fine-scale fish movements and hydrodynamics based on in-situ investigations. In the presented study, ...
