Anton van Rinsum entered in 1921 the Bavarian governmental service as a civil engineer. Based on his designs of dams along the Danube River he submitted in 1934 a PhD thesis to the Technical University of Munich TUM, published in 1935. van Rinsum was appointed collaborator of Bayerische Landesstelle für Gewässerkunde in 1938 of which he took over directorship in 1950. He retired in 1955. In parallel he served professional associations to develop practical aspects of water resources in Germany, particularly in Bavaria. van Rinsum was a Lecturer of water resources at TUM and was a consultant in these questions after having retired.

van Rinsum devoted his early career to the velocity and discharge distributions in natural rivers. Following earlier proposals of Gotthilf Hagen (1797-1884), Philipp Forchheimer (1852-1933), Robert Jasmund (1853-1935), Eduard Beyerhaus (1857-1926), Richard Siedek (1859-1949), among others, he derived a velocity formula that is composed of a finite bed velocity plus an addition of elliptical shape. This formula contains three parameters depending on the bed material and the river shape. The formula was popular for some time but eventually replaced by a scientific approach once the modern boundary layer concept had been accepted after World War II.
