Sandy sediment transport along Anapa bay bar (the Black sea, Russia)

The suspended sediment flux along underwater slope of Anapa bay-bar (the Black Sea, Krasnodar region), is calculated. This flux, created under the influence of currents and wind waves, is calculated for the period from 1979 to 2015. Characteristic (i.e., characterizing the order of magnitudes) volumes of material moving along the shore are as follows: from northwest to southeast -40000 m(3)/year, from southeast to northwest -15000 m(3)/year. Almost throughout the entire length of the bay bar, there is a predominance of sediment flow directed from NW to SE. The exception is the southern part of the bar, adjacent to Anapa city, which is on average characterized by the prevalence of the flow from the SE to the NW. Change of sign of general sediment transport is observed southwards of the Vityazevo village. The presence of two-directional sediment flow ensures the existence and dynamic equilibrium of the two parallel underwater coastal bars along the Anapa bay-bar.
