Abstract

Previous studies of the Yenisei delta dynamics in the second half of the twentieth century showed a slight increase in its area, prevailing over erosion. In this work, images from Landsat-7 satellites of 1999 and Sentinel-2B in 2017 were used to study the changes in the first decades of the 21st century. A pre-map was obtained for them showing the land formation areas at the water site (sediment accumulation) and appearing water instead of land (erosion of the coast). Small areas of these changes can’t be displayed on observing maps, but the characteristics of the accumulation and erosion intensity is possible, corresponding to the average annual velocity of the coastline moving. Such maps, compiled in the scale of 1
