Walter (Valter) Rand was born in Estonia. After having served as a soldier, he initiated studies at Reval Technical University in 1936, from where he graduated as a civil engineer in 1941. In 1942 Rand was given a fund for a research stay at the Karlsruhe Technical University, from where graduated with the Dr.-Ing. title in 1943. After World War II, Rand moved to the United States, where he was finally a professor of hydraulic engineering at the City College of the City University of New York.

Rand is known for various works in hydraulic engineering relating mainly to energy dissipators. During his PhD thesis he investigated drop structures as an alternative to conventional hydraulic jump stilling basins. His results were generalized in the 1955 paper, a time when being an associate professor at the New York City College. In 1965, Rand presented a paper towards the understanding of the various flow types in stilling basins associated with the presence of a sill. He presented detailed observations that describe the effects of sill front location relative to the toe of the hydraulic jump, the effect of the relative sill height and the Froude number in the approach flow channel. These observations were then compared one year later with the flow features across so-called dentated sills, as originally introduced by Theodor Rehbock (1864-1950), the founder of the Karlsruhe Flussbau-Laboratorium, where Rand had submitted his thesis.
