ABSTRACT
In this short paper an attempt is made to bring to light examples of Swedish influence on Norwegian hydrological knowledge before the Swedish-Norwegian union in 1814. Dano-Norwegian topographic literature from the 16th, 17th and 18th centuries is used as source. Publications by Swedish scientists were read and used as references by Norwegian writers during that period. The examples given illustrate the state of hydrological knowledge in the Scandinavian countries two to three hundred years ago.
