Remote sensing methods are widely used (1990s) to study erosion processes. Remote sensing makes an important contribution to the assessment of erosion at various spatial levels. The use of remote sensing techniques has the potential to identify eroded areas and monitor erosion processes at the regional level. lines, zones of influence of geomorphological processes and quantitative indicators. The coastline and its dynamics of the coastal areas of the Absheron peninsula (according to geomorphological zoning: from Sumgayitchay to the Jeyrankechmez river) were studied using ArcGIS software using Landsat MSS, TM, OLI images of the coastal zone of the Caspian Sea for 1986, 2002 and 2019. The calculation was carried out using the WLR statistics of the DSAS method. The calculation was carried out using the WLR statistics of the DSAS method. Negative values obtained during the calculation indicate erosion, while positive values indicate accretion. Remote sensing-based methods provide a cost-effective way to investigate erosion or build-up where there are no available areas or direct field methods are expensive. An analysis of the compatibility of remote sensing data for identifying areas of erosion and accretion processes (accumulation), monitoring, assessing the impact on soil and other objects, shows the use of a number of images to solve these problems.
