KOCHINA, PELAGEYA YAKQVLEVNA (Hydrodynamicist) 

 ' P. Ya. Kochina was born May 1, 1899. In 1921 she graduated 

 from Petrograd University. From 1919 she worked in the main 

 geophysical observatory. She taught at the Ways of Communi- 

 cation Institute, at the Institute of Civil Fleets, and at Lenin- 

 grad University where she was made professor in 1934. Begin- 

 ning in 1935 she worked in the Mathematics Institute and 

 subsequently in the Institute of Mechanics of the U.S.S.R. Acade- 

 my of Sciences. She was elected a Corresponding Member of 

 the U.S.S.R. Academy of Sciences in 1946 and in 1958 an Acade- 

 mician. In 1945 she was awarded a Stalin Prize. 



Kochina' s major interest is the theory of filtration. She has 

 solved many important problems, which are associated with the 

 movement of ground waters and oil in porous media. In 1952, 

 she wrote a monograph on the ** Theory of Ground Water Move- 

 ment," summarizing the Soviet work in the field of filtration. 

 She has also worked in dynamic meteorology, stability of plates, 

 and theory of tides in basins. Kochina was the editor of the 

 first collection of the works of Kovalevskaya, the Russian 

 mathematician, and published articles of Kovalevskaya' s life 

 and work.
