Mikhail Alekseevich Dementiev graduated as naval architect from the Ship-Building Institute of Saint Petersburg Polytechnic Institute in 1926. In 1930 he submitted there his PhD thesis and was promoted to Doctor of Sciences in 1944. In 1929, Dementiev joined the Scientific Melioration Institute, then the NIIG and from 1940 the Leningrad Hydraulics Institute VNIIG, to stay there all his career. As an expert of sediment transport processes he headed from 1934 to 1974 its Hydromechanics Laboratory.

\

Dementiev started working in river engineering under the supervision of Mikhail Andreevich Velikanov (1879-1964). His first works related to the theory of interchange between water flow and sediment transport. He then proceeded to questions in practical computation of sediment transport and deposition of sediment in water flow. Dementiev was also involved in the design and the execution of earth dams, such as the schemes of Kuybishev, Bratsk and Aswan in Egypt. Later he contributed to the understanding of ash and slag transport for thermal power stations. A particular experimental setup was created at the Siberian branch institute of VNIIG to study these phenomena. Dementiev was a Member of the International Association of Hydraulic Research IAHR and thereby was involved in the preparation of its Leningrad Congress in 1965, where he was the chairman of the High-speed flows section.
