Knut Alfredsen
Background and activities
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.
