Boris Fridrikhovich Reltov graduated in 1927 from Leningrad Polytechnic Institute LPI as a hydraulic engineer and there got in 1938 the PhD title. He was from 1928 a scientific collaborator of the Leningrad Hydraulic Laboratory VNIIG, lectured in hydraulic engineering from 1931 at LPI and headed from 1939 the VNIIG hydraulic laboratory. Reltov was from 1946 to 1950 chief of the Physical-Chemical Laboratory of VNIIG soil mechanics Department, headed from 1950 to 1970 this Laboratory and then until 1974 the Laboratory Sector. Until retirement in 1990, Reltov was a senior scientific collaborator of VNIIG.

Reltov investigated a number of Soviet hydropower complexes, including the Svirstory, the Belomor-Baltic Canal, Nivastory, Ulbastory and the Sredvolgostory schemes. He was also involved in the formulation of the main laws for the electro-osmotic filtration and developed methods for understanding the relation between a ground mass and the excavator bucket and dump-body trucks. He elaborated methods for strengthening poor soils with the rapid sliming method as used in metallurgy, ore mining and mining processing. Reltov also proposed a two-term law for friction of coherent soils, and the percolation laws of saline soils, as well as the rheologic properties of soils in general. These issues were essential for designing earth dams, of which the Soviets have completed large structures. Reltov was a Member of the International Association of Soil Mechanics and Foundation Engineering. He was presented the Order of the Labor Red Banner in 1951, next to various Premiums and Medals from his country.
