Advancing ecohydraulics and ecohydrology by clarifying the role of their component interdisciplines

Gosselin, Marie-Pierre; Ouellet, Valerie; Harby, Atle; Nestler, John (Journal article; Peer reviewed, 2019)

Increasing awareness of the complexity of river ecosystems has led to the emergence of integrative disciplines that combine topics in river physical and ecological processes, exemplified by the disciplines of ecohydrology, ...

Analysis of environmental impacts of a pump-storage system between two Norwegian reservoirs considering climate scenarios

Pinelli, Anna; Adeva Bustos, Ana; Toffolon, Marco; Alfredsen, Knut Tore; Harby, Atle (Doctoral thesis, 2022)

Assessing the energy potential of modernizing the European hydropower fleet

Quaranta, Emanuele; Aggidis, George; Boes, Robert M.; Comoglio, Claudio; De Michele, Carlo; Patro, Epari Ritesh; Georgievskaia, Evgeniia; Harby, Atle; Kougias, Ioannis; Muntean, Sebastian; Pérez-Días, Juan; Romero-Gomez, Pedro; Rosa-Clot, Marco; Schleiss, Anton J.; Vagnoni, Elena; Wirth, Markus; Pistocchi, Alberto (Peer reviewed; Journal article, 2021)

About 50% of all hydropower plants (HPPs) worldwide were originally commissioned more than 40 years ago, so that the advanced age of the fleet is a major concern across all continents, and especially in Europe. The ...

Betydningen av vannkvalitet, vannføring og andre miljøforhold for tilstanden hos laks- og ørret-bestanden i Jørpelandsvassdraget

Lund, Roar A.; Hindar, Atle; Harby, Atle; Larsen, Bjørn Mejdell; Johnsen, Bjørn Ove (NINA rapport;, Research report, 2006)

Det er tilsynelatende så begrensede gyteområder i Jørpelandselva at dette begrenser den na-turlige produksjonen i deler av vassdraget. I området nedenfor kraftverket er det siden 1995 utsatt fisk i mengder som har vært ...

CEDREN final report

Classification of hydropeaking impacts on Atlantic salmon populations in regulated rivers

Bakken, Tor Haakon; Harby, Atle; Forseth, Torbjørn; Ugedal, Ola; Sauterleute, Julian Friedrich; Halleraker, Jo Halvard; Alfredsen, Knut (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 ...

Cost-effective environmental mitigation measures i hydropower rivers

Harby, Atle; Adeva-Bustos, Ana; Hanse, Bendik Torp; Noble, Richard A.A.; Rutkowski, Terese (Others, 2019)

Cost-effective mitigation measures in regulated rivers

Harby, Atle; Rutkowski, Terese; Fjeldstad, Hans-Petter (Others, 2018)

Development of small versus large hydropower in Norway– comparison of environmental impacts

Bakken, Tor Haakon; Sundt, Håkon; Ruud, Audun; Harby, Atle (Peer reviewed; Journal article, 2012)

This study has compared the accumulated environmental impacts from 27 small-scale hydropower plants with 3 large hydropower projects. The results show a slight tendency that large hydropower has a lower degree of impacts ...

Downstream fish passage evaluation using barotrauma detection sensors at the Kongsvinger and Funnefoss power plants

Carolli, Mauro; Tuthan, Jeffrey; Sabil, Sahra Naima; Museth, Jon; Harby, Atle (SINTEF Energi. Rapport;, Research report, 2024)

Downstream migrating fish face injury and mortality risks from turbines and hydraulic structures due to cavitation, pressure drops, blade strikes, and hydraulic shear. Waterproof autonomous sensors measured these risks by ...

Evaluating Cost Trade-Offs between Hydropower and Fish Passage Mitigation

Venus, Terese E.; Smialek, Nicole; Pander, Joachim; Harby, Atle; Geist, Juergen (Peer reviewed; Journal article, 2020)

To promote the sustainable management of hydropower, decision makers require information about cost trade-offs between the restoration of fish passage and hydropower production. We provide a systematic overview of the ...

Forslag til metode for klassifisering av hydromorfologisk tilstand i norske elver

Harby, Atle; Bakken, Tor Haakon; Dervo, Børre Kind; Gosselin, Marie-Pierre; Kile, Maia Røst; Lindholm, Markus; Sundt, Håkon; Zinke, Peggy (SINTEF Rapport;, Research report, 2018)

Denne rapporten anbefaler metoder og forvaltningsverktøy for forbedret karakterisering og klassifisering av hydrologisk og morfologisk tilstand av vannforekomster i Norge. Det anbefales en systematisk inndeling i fire ...

Greenhouse Gas Emissions from Freshwater Reservoirs: What Does the Atmosphere See?

Prairie, Yves T.; Alm, Jukka; Beaulieu, Jake; Barros, Nathan; Battin, Tom; Cole, Jonathan; del Georgio, Paul; DelSontro, Tonya; Guerin, Frédéric; Harby, Atle; Harrison, John; Mercier-Blais, Sara; Serca, Dominique; Sobek, Sebastian; Vachon, Dominic (Journal article; Peer reviewed, 2017)

Freshwater reservoirs are a known source of greenhouse gas (GHG) to the atmosphere, but their quantitative significance is still only loosely constrained. Although part of this uncertainty can be attributed to the difficulties ...
