ABSTRACT
Andersen was in the 1970s besides Engelund a leading figure of hydraulic engineering in Denmark. Next to a number of books on harbour structures, hydraulics and hydraulic engineering, he also presented some notable papers on the surface resistance of pipe flow thereby accounting for the results of the Germans Ludwig Prandtl (1875-1953) and Johann Nikuradse (1894-1979), and of the English Cyril Frank Colebrook (1910-1997) and Cedric Masey White (1898-1993). Andersen also investigated the features of the undular hydraulic jump, thereby including the effects of streamline curvature.
