Svein Vigander moved to the United States in 1956 to obtain education from the Purdue University in Lafayette IN. He gained the MS in fluid dynamics in 1959 and then worked for the Kimberly-Clark Corporation in Neenah WI. There he used physical flow models to develop new technology for paper forming and investigated re-aeration methods for water quality improvement. From 1961 to 1965, Vigander worked on a PhD thesis at the University of Kansas and then moved as a research engineer to the Engineering Laboratory of the Tennessee Valley Authority TVA in Norris TN. He there supervised the research section and headed the fluid systems group.

\

Vigander published work in the areas of flow induced vibration, physical flow modeling, environmental fluid mechanics and polyphase flow. His contributions include the development of instrumentation, field testing, the analysis of density currents in stratified reservoirs, the development of multiport diffusers for reducing environmental effects of thermal discharges for power plants, and pioneering work in vibration signature analysis for predictive maintenance of fluid machinery. He was an active Member of the American Society of Civil Engineers ASCE, the International Association of Hydraulic Research IAHR and the American Academy of Mechanics.
