Using Of Remote Sensing Data To Study Transformation Of The Solenoye Lake Bay-Bar

Anapa bay-bar is largest sand accumulative coastal form of the Caucasus Black Sea coast. Bay-bar of the Solenoye Lake is the northern part of the geosystem of Anapa bay-bar. Research opportunities of the relief and the landscape-morphological structure of the bay- bar transformation using remote data are shown in this paper. Simultaneous satellite images from open sources were the basis for analyzing of the dynamics of the sea and lagoon shores of the bay-bar. In addition airborne laser scanning and digital aerial photography of the Solenoye Lake bay- bar have performed in 2013 and 2015. Further, aerial laser scanning data and aerial photography were used to create high-precision digital elevation models (DEMs) and orthophotoplans of bay-bar and adjacent coastal sections. The analysis of digital elevation models made it possible to obtain linear and volumetric morphometric characteristics of this accumulative form. Relief and plan cover changes of the bay-bar, recorded using differential DEM or found in photographs, have both anthropogenic and natural genesis. Relief changes caused by hydrogenic processes are concentrated within the beach and erosion cuts. It has been established that beach topography restructuring occurs in almost every severe storm. The alternation of areas with increasing and lowering surface and fluctuations of the beach width due to coastline migration is characteristic. Most of the changes of the relief and vegetation in the central part and on the lagoon coast of the bay-bar are caused by anthropogenic impact. Leveling surfer of bay-bar for buildings, tents, parking and the dike creation to protect territory are marked. In the future, the destruction of dikes under storm influence and the dune restoration under influence of eolian processes are observed.
