VERESHCHAGIN 412 



Member of the U.S.S.R. Academy of Sciences. In 1948 he was 

 made an Honored Scientist of the R.S.F.S.R. 



Velikanov initially engaged in the study of flow stations 

 (organized by him) and water balance. In 1932 he transferred 

 to an experimental study of problems of river-bed hydrology in 

 laboratories established under his direction for the Hydro- 

 meteorological Service and the U.S.S.R. Academy of Sciences. 

 Velikanov studied water balance, large scale turbulence of 

 river streams, mechanism of water pumps and the behavior 

 of river beds. He took part in many large scale hydraulic 

 projects.

L. F. Vereshchagin was born in 1909. In 1930-32, he was a 

 postgraduate student, and 1932-34 he worked as a senior engi- 

 neer at a turbogenerator plant. He was an engineer, 1934-39, 

 and subsequently chief engineer at the Physico-Technical Insti- 

 tute in Khar'kov. From 1939-1954, he was laboratory super-
