The establishment of the survey of seashores is considered of great economic 

 importance for the rational planning and developing of maritime construction 

 for coastal protection, harbors, and landing facilities and coastal engi- 

 neering in general. 



Artificial Seas of U.S.S.R. - The construction of immense retention 

 reservoirs with dimensions comparable to those of largest natural inland 

 lakes, underway for the past 40 years within the hydrotechnical program of 

 Russia's water resources, was initiated by the Great Volga Waterway C14) f 

 in 1926. As an example, Kuybyshev "Sea", an artificial storage reservoir 

 created by a multiple-purpose dam, raises the Volga stage by 24 m. at 

 Kuybyshev and extends for a distance of 500 km. (310 miles). It averages 

 40 to 60 km. (25 to 37 miles) in width and retains 38 cu. km. (31 million 

 acre-feet) of water. These artificial reservoir creations are subject to 

 coastal processes of their own and obey certain laws typical of them. An 

 important consideration in these reservoirs is the role played by wind waves 

 up to 3.5 m (12 feet) high, and their action on the shores. These phenomena 

 have become the subject of studies and investigations of experts in a vari- 

 ety of sciences (14-16, 18-22, 28, 29, 31, 41-43, 60-63, 68,69, 72,73, 75-79, 

 83-85) # xhe changes in the shoreline of these reservoirs, in the course 

 of filling up, inhibit the planning and construction of industrial plants, 

 agricultural installations, and human settlements, as well as of piers, 

 harbors, railroad lines, and highways along the shore. The key to these 

 problems is to originate reliable methods for predicting the changes in the 

 shores during the filling-up process of the reservoir. The experience and 

 theory on the dynamics and morphology of seashores is of very little use, 

 because these changes include both the process of formation of the shore 

 slope during the reservoir filling and those during the operation of the 

 waterway and hydropower plant at various stages of flood. The concept of 

 uniformity in the process of formation of shore slope above and under the 

 water is the basis for the methods presently used for the reservoir con- 

 struction. The shore slope is considered a surface on which the destruc- 

 tion of the energy of waves attacking the shores takes place. 



Silting Processes in Harbors and Navigation Canals - Study of silting 

 is a very important part of Soviet coastal research with particular regard 

 for disintegration of shores along detrital and sandy coasts. Numerous 

 investigations are carried on, to establish reciprocal relations between 

 a variety of structures connected with maritime constructions, such as 

 breakwaters, moles, shore revetments, groins, and others (16,69) e The
