“…From these observations it is possible to draw a conclusion, that for this bay-bar site the unstable hydrodynamic mode defining frequent change of sediments movement direction (Figure 3) is characteristic. Nevertheless, the configuration of the Anapka river old channel confirms the resulting prevalence of sediments stream (Kosyan et al, 2011) directed to the south. The important components of Anapa bay-bar lithodynamic balance are eolian processes.…”

The total length of Ukraine and Russia Black Sea coastal line makes almost half of Black Sea coast summarized extent. The policy of coastal zone development and management pursued by these states exerts an essential influence on the entire Black Sea. For the solution of the practical problems arising during economic development of the coast, frequently it is required to receive quickly the information on dynamics of coast, especially of the accumulative one. The data acquisition of the field instrumental observations requires the long expeditionary works and the time for the subsequent office treatment of results. The use of space pictures allows estimating dynamics of accumulative coastal forms of any scale and giving a complete picture of the area coast changes. The resorts Anapa (Russia) and Crimea (Ukraine) have been used as test areas.

“…Рассмотрим климатические особенности вдольбереговых потоков донных отложений в прибрежной зоне моря на примере Анапской пересыпи. Общей тенденцией динамики пляжей Анапской пересыпи является практически повсеместное сокращение их ширины, вызванное целым рядом факторов как природного, так и антропогенного происхождения (Kosyan et al, 2011). К факторам природного характера относятся, в первую очередь, климатические колебания параметров ветрового волнения, определяющие силу и продолжительность гидродинамического воздействия.…”

Due to the development of measuring instruments, a more detailed analysis of the wave field and the field of suspended sediments spatio-temporal characteristics has become possible. Through the efforts of Russian specialists over the past decades: A unique database of observations of the sediment movement in storm situations in different physical and geographical areas of the coastal zone of the Black, Baltic, North, Mediterranean, South China Seas has been collected, supplemented by extensive data of laboratory experiments in the best laboratory in Europe (Hannover, Germany). New experimental material has been obtained to determine the physical features of sediment transport by wave flow. The main mechanisms controlling the amplitude and phase relationships of the concentration fluctuations and discharge of suspended sediment on time scales less than the period of the peak of the wind wave spectrum are considered. The presence of low-frequency fluctuations in sediment concentration with a period of the order of several periods of wind waves and an amplitude several times higher than the average value of concentration is noted. The previously unexplored problem of the wave energy frequency distribution in the spectrum of surface waves influence on the sediment transport has been analyzed. Differences in the response of the washed-out bottom to an external disturbance, represented by irregular surface waves with constant integral characteristics (significant wave height and period of the spectrum peak) and variable wave energy frequency distribution, were revealed. The influence of swell waves on the redistribution of bottom sediments in the sea coastal zone was investigated. It is shown that dividing the wave field into separate components allows a more correct description of the spatiotemporal structure of surface waves, as well as a significant refinement of the bottom sediment transport schemes in the coastal zone. Using the example of the Anapa bay bar, it is shown that situations are possible in which the alongshore flow of bottom sediments is almost completely determined by swell waves. The results of field and laboratory experiments make it possible to determine the directions for further research on the creation of physically based models of sediment transport by waves and wave currents.
