Accumulative coast dynamics estimation by satellite camera records

摘要

We present the methods and results of investigation of the Anapa bay-bar shoreline dynamics, obtained from the analysis of historical and recent data of satellite imaging and aerial survey. It was revealed that several erosion regions exist along the Anapa bay-bar shore (the revealed retreat of the water edge is greater than 70 m over 50 years). A relatively stable region was also found there. In addition, the analysis of short-period dynamics of the water edge location revealed that the short-term displacement of the water edge relative to its mean position is as high as 30 m. These data clarified the dynamics of the Anapa bay-bar shoreline, which is important for the understanding of lithodynamic processes in the coastal zone and developing the forecast of the further evolution of the bay-bar geosystem.
