ASSESSMENT OF THE CASPIAN COAST DYNAMICS USING GEOSPATHIC TECHNICAL METHODS (ON THE EXAMPLE OF THE ASHBERON COASTAL REGION)

T.T.Mamishova

Abstract. The fall in the level of the Caspian Sea in recent years has a serious impact on the infrastructure of the coastal zone. The presented article is devoted to the study of the identification and dynamics of the coastal zo­ne and the coastline of the Absheron subregion of the Cas­pian Sea, zones of influence of geomorphological pro­cesses and quantitative indicators for 1986 and 2019 using Landsat MSS, OLI satellite images. Satellite ima­ges were also developed with the appropriate software, and the accretion, field stability, and erosion processes in the study area were quantified using various semi-auto­ma­tic methods ((Tasseled Cap (Bright­ness, Wetness, Greenness) and DSAS-Digital Shoreline Analysis System)). The results are presented in the form of maps and tables, graphically showing the changes occurring in the coastal zone as a result of falling sea level.

Keywords: morphology, coastline, dynamic, satelli­te image, remote sensing, abrasion, accumulation.
