dynamics and shore zone investigations and which should be subjected to 

 international cooperation. These problems are: 



a) transformation of wave movements in shallow zones and study of 

 wave velocities and their assymetry, 



b) currents generated by waves and other currents in the shore zone, 



c) mechanism of moving and shifting of debris of different sizes, 



d) establishment of bottom equilibrium profile, 



e) study of migration of debris along the shore and of physical 

 parameters of debris streams, 



f) formation of embankments and straightening of shores, 



g) laws of the shore zone development as a part of general geo- 

 physical picture of lithosphere evolution, and 



h) physical processes in the shore zone as part of the total energy 

 balance of the earth's surface. 



The acceptance of the Soviet proposal in Helsinki by IAPO, and 

 appointment of V. P. Zenkovich to chairmanship of the Committee for the 

 study of dynamics of shores and coastal zone, indicates a certain inter- 

 national recognition of recent achievements of Soviet coastal scientists 

 and oceanographers. 



It is not as yet clear whether the Committee will be successful in 

 promoting the proposed international cooperation. 



ORGANIZATION AND EXECUTION OP COASTAL RESEARCH IN U.S.S.R. 



Soviet entry into scientific investigations of shores and coastal 

 zones of oceans, seas, and lakes is of relatively recent origin. For 

 example, the publication of the works by V. P. Zenkovich in 1946 ( 90-92 ) f 

 are comparable to that of the United States of 1919 - when the book by 

 D. W. Johnson: "Shore Processes and Shoreline Development" (13), was 

 published. 



The effort of Soviet scientists, oceanographers, and engineers 

 specializing in coastal research since World War II, however, deserves 

 special attention. A group of individuals associated with Zenkovich, 

 among them, in particular N. N. Dzhunkovskiy (lf2), Y. G. Kachugin(15 ,16), 

 N. Y. Kondrat'yev (21-27), 0. K. Leont'yev (33-40) , V. V. Longinov (44-59), 

 B. A. Pushkin (61-71), G. S. Solotaryev (77,78), and others, was able to 

 produce voluminous scientific and technical literature on the subject.
