Quantitative changes of Verbyanaya spit state in the Azov Sea according to the annual monitoring data
Research of Verbyanaya spit is initiated by LLC «NK «Priazovneft» within the framework of environmental monitoring carried out in their license area. According to the topographic and bathymetric measurements and GIS modeling, are shown quantitative estimates of inter-annual transformations of Verbyanaya spit body (the Azov Sea) are carried out in 2005-2014. The inter-annual dynamics of sediments has its peculiar features in each of the balance period. There is a 2-3-year periodicity in reorganizations of the underwater slope with an overall positive balance for the analyzed period.The length of the measurements site in the area of the spit is about 9 km. Verbyanaya spit monitoring program includes control of spatial-temporal reconstructions of the beach line and position of the edge line of estuary and the sea coast through regular geodetic measurements. The data of 10 topographic-bathymetric surveys (2005-2014.) are used. Of some interest is the spit’s dynamics under the influence of the above-mentioned factors of its re-composition to estimate mutual effect of the changes of the body’s planned configuration of the built coast-protection dam and beach and underwater slope modes.
