Knut Alfredsen
Bakgrunn og aktiviteter
Professor i hydrologi ved institutt for vann- og miljøteknikk. Foreleser hydrologi/vassressursdelen av BM2 Vann og miljø, grunnkurset i hydrologi, hydrologisk modellering og koordinerer/foreleser kurset i modellering av vassressursar. 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.
