List of doctoral thesis in the Waterpower laboratory since 1950.
This list corresponds to (1) the main research conducted in the Waterpower laboratory and (2) the main supervisor is from the Waterpower laboratory and (3) the thesis is defended in NTH/NTNU. The actual list of doctoral theses extends beyond what is stated here, as academic professors often engage in co-supervising doctoral theses at other universities as part of international collaborations.
