Lennart S. Rahm graduated as a civil engineer in 1942 from the Royal Institute of Technology KTH, Stockholm and there gained his PhD title in 1953. He was then until 1960 a Lecturer of hydraulics at KTH and in parallel an engineering consultant. Rahm was appointed in 1960 professor of hydraulic engineering at Chalmers University of Technology, Göteborg, but passed away in 1976 for unknown reasons. He was an ICOLD Member of the Swedish National Committee joining its Advisory Board from 1961. He made several study tours to Western European countries, the USA and Canada and he held positions at the Department of his university.

In the 1950s, Rahm headed the hydraulic laboratory of KTH under the guidance of Bo Hellström (1890-1967). Rahm was then interested in flows at intakes and in the features of air-water flows in such a hydraulic set-up. From 1958 he lectured hydraulics at the Swedish Meteorological and Hydrological Institute. As a consultant, Rahm contributed within the Svenska Kraftkontoret GmbH in the late 1950s to works and the development of hydropower and pumping stations, and to irrigation works. Once at Chalmers University, he added to the knowledge of density currents and to their technical control in the marine environment, then a typical research topic in hydraulic engineering. He was also interested in the erosion of incohesive soils, a research topic that is still widely under progress these days.
