Vladimir Jezdinský graduated as a civil engineer from the Czech Technical University, Prague, as a civil engineer in 1959. He then joined the Water Resources Administration of Plzeň designing a weir on the Úhlava River in Nýrsko, Bohemia. From 1961, Jezdinský was a research student at the Institute of Hydrodynamics of the Czechoslovak Academy of Sciences CSAV under Jan Smetana (1883-1962). During his PhD study, he passed one year under the supervision of Hunter Rouse at the Institute of Hydromechanics of Iowa State University, Iowa USA. In 1968, Jezdinský obtained at CSAV the title Candidate of Technical Sciences. He joined from 1970 to 1971 the University of Karlsruhe, Germany and then returned to CSAV until 1988, when joining the T.G. Masaryk Water Research Institute. After his eye disease had appeared in 1990, Jezdinský retired in 1992.

Jezdinský collaborated all through his career with the Institute of Hydrodynamics of the Czech Academy of Sciences. This Institute was created in 1953 from the Laboratory for Water Management, whose current name was given in 1958. The Institute considers theoretical and experimental works in the following fields: Hydrodynamic processes in multiphase systems both for laminar and turbulent fluid flows, Rheological properties of non-Newtonian materials, Modeling transport of matter in the biosphere by climatic changes and human activities, and Rainfall-runoff processes including extreme water events by a mathematical modeling. Jezdinský obviously worked in the first department and there steadily contributed to the knowledge of air-water two-phase flows, either relating to turbulent jets, or the rise velocity of air bubbles in liquids. Based on his PhD thesis, he in parallel added research to the cavitation phenomenon as experienced in conduit expansions.
