Combining Fish Passage and Sediment Bypassing: A Conceptual Solution for Increased Sustainability of Dams and Reservoirs
Foldvik, Anders; Silva, Ana T.; Albayarak, Ismail; Schwarzwälder, Kordula Valerie Anne; Boes, Robert M.; Rüther, Nils (Peer reviewed; Journal article, 2022)Sedimentation is one of the main eco-morphological and technological challenges associated with reservoirs. Sedimentation not only reduces the functional capacity of a reservoir by filling it, but also changes downstream ... -
Comparing land use impacts using ecosystem quality, biogenic carbon emissions, and restoration costs in a case study of hydropower plants in Norway
Lillesund, Vilde Fluge; Hagen, Dagmar; Michelsen, Ottar; Foldvik, Anders; Barton, David Nicholas (Journal article; Peer reviewed, 2017)Purpose Habitat destruction is today the most severe threat to global biodiversity. Despite decades of efforts, there is still no proper methodology on how to assess all aspects of impacts on biodiversity from land use and ... -
Exploring sensitivities to hydropeaking in Atlantic salmon parr using individual-based modelling
Hedger, Richard David; Sundt-Hansen, Line Elisabeth Breivik; Juarez-Gomez, Ana; Alfredsen, Knut Tore; Foldvik, Anders (Peer reviewed; Journal article, 2023)Hydropeaking (the release of water pulses at hydropower plants) results in temporaryreductions in river channel water-covered area downstream, which may cause fishmortality through stranding. We used a mechanistic modelling ... -
Interactions between local population density and limited habitat resources determine movements of juvenile Atlantic salmon
Teichert, Maxim; Foldvik, Anders; Einum, Sigurd; Finstad, Anders Gravbrøt; Forseth, Torbjørn; Ugedal, Ola (Journal article; Peer reviewed, 2017)Competition for limited resources and the resulting density-dependent processes are key factors in driving stream salmonid population dynamics. Here we test for the combined effects of density and shelter availability on ... -
Konsekvenser for sjøørret, villaks og fugl ved utfylling av deler av elveosen til Stjørdalselva. Kunnskapsoppsummering og foreløpige forslag til avbøtende og kompenserende tiltak
Davidsen, Jan Grimsrud; Husby, Magne; Foldvik, Anders (NTNU Vitenskapsmuseet naturhistorisk notat;, Research report, 2020) -
Spatial distributions and productivity in salmonid populations
Foldvik, Anders (Doktoravhandlinger ved NTNU, 1503-8181; 2013:235, Doctoral thesis, 2013)This thesis presents analysis and fieldwork investigating how the effect spatial distributions and spatial relationships have on population growth in two anadromous salmonid species, Atlantic salmon and brown trout. The ...
