Knut Alfredsen
Om
Professor i hydrologi ved institutt for vann- og miljøteknikk. Foreleser hydrologi/vassressursdelen av BM2 Vann og miljø, grunnkurset i hydrologi og hydrologisk modellering. Ansvarleg for Teknostart innan vassfag. Forskningsinteressene dreiar seg hovudsakleg om miljøverknader av vassdragsutbyggingar, kaldklimahydrologi knytt til is i vassdrag og tema rundt modellering av hydrologi og vassressursar.
Forsking
My research is mainly has a focus on cold climate processes in rivers and lakes, environmental impacts of hydropower and applications of models in hydrology and water resources.
My work covers field measurements, data analysis and modelling.
HydroCen
Senter for fornybar energi (FME). Forskning på modellering av elver basert på fjernmålte data og kopling av dette mot fisk.
Supervisor for Dr. Håkon Sundt.
HydroFlex
The goal of Hydroflex is to develop a turbine capable of multiple stops pr. day. My contribution was to evaluate downstream consequences and provide methods of mitigation of adverse effects of rapid flow changes on fish.
Research on river ice
Several projects focused on river ice formation, ice growth, river ice modelling and impacts of river ice.
Sagelva Research Catchment
Sagelva research catchment was established in 1973. There are two climate stations and three discharge stations in the 8 km2 catchment.
Klima 2050
Estimation of runoff from small catchments. Supervisor for Dr. Aynalem Tsegaw.
Trygg Elv
The Trygg Elv project aims at defining critical points in rivers during floods using automatic methods. The project will develop tools that can be used to detect and prioritise critical areas during floods meant for planning and operational use.

Review of Ice Effects on Hydropower Systems
Ice on reservoirs and in regulated river can be an issue for hydropower operation, and hydropower development will influence ice formation. This paper by Gebre et al. provides a thorough overview of ice effects related to hydropower systems.
Proceedings of the 25th IAHR symposium on ice 2020
Proceedings from the 25th IAHR ice conference in Trondheim in November of 2020. Edited by: Knut Alfredsen, Knut Vilhelm Høyland, Wenjun Lu, Per Ludvig Bjerke, Leif Lia and Sveinung Løset.
I publish papers in peer-reviewed journals and books, contribute to conferences and publish reports from applied projects. For a full list, see the link to the CRISTIN system on this page, or use the Researchgate link at the top of the page.
