ABSTRACT
ELEVATORSKI 23.03. 1909 New Providence NJ/USA 20.06. 1997 Bonsall CA/USA Edward Arthur Elevatorski’s professional career is poorly known. He was in the mid-1950s hydraulic engineer at the Bureau of Reclamation USBR, Salt Lake City UT, and in the late 1950s head of the Hydraulic Laboratory and assistant professor of civil engineering, the University of Arizona, Tucson AZ. He was mainly known for his 1959 book on hydraulic energy dissipators, which received mixed comments, however, from the hydraulic community. The book mentioned includes 20 chapters, namely 1 Functions of energy dissipators, 2 Basic concepts of open channel flow, 3 Elements of hydraulic jump, 4/5 Hydraulic jump in rectangular/ non-rectangular channels, 6 Hydraulic jump in sloping channel, 7 Energy dissipation by the hydraulic jump, 8 Hydraulic-design criteria, 9 Hydraulic-jump-type stilling basins, 10/12 Stilling-basins, 13 Outlet-works control mechanisms, 14 Jet-diffusion and impact stilling basins, 15 Special stilling basins, 16 Ski-jump and arch-dam energy dissipators, 17 Drop-structure stilling basins, 18 Bucket-type energy dissipators, 19 Model tests and hydraulic similitude, 20 Erosion below dams. Apart from the 1935 book of Armin Schoklitsch (1888-1969), Elevatorski’s book may be considered the first on the subject topic. It is a basic textbook for hydraulic engineers in which the fundamental concepts of open channel flow are described, including the energy and momentum conservation equations and their applications to practice. The book is excellently illustrated with figures and photographs explaining the concepts described, and it includes a remarkable list of referenced on the topic. The book presents the ten different types of stilling basins as introduced by Alvin J. Peterka (1911-1983) and Joseph N. Bradley (1903-1993), popularizing their work internationally. It also contains a short overview on laboratory modeling of energy dissipators. Later in his career, Elevatorski obviously entered the mining world, dealing mainly with gold and its occurrence in the world. Anonymous (1958). E.A. Elevatorski. Desert College of Engng: 107. Univ.
