Knut Alfredsen
About
I am professor in hydrology at the department of hydraulic and enviornmental engineering. Responsible for teaching water resources in the basic course in water and environment, hydrology and hydrological modelling. Main research interests within environmental impact assessment, hydrology of rivers and lakes in cold climate and aspects of modelling water resources.
Research
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.
Publications
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.
