The article discusses the possibilities of assessing the state of river beds and changes in them using remote sensing technologies (RS) and geographic information systems (GIS). With the help of geoinformation technologies, an assessment of deformation phenomena over the past 25 years in the channel of the Sokh river, which was chosen as the object of research, was given. Channel phenomena have been studied using data obtained from satellites. To analyze the situation, a model of the Landsat satellite was selected. The currently widely used official Glo Vis website was used to download the data. Data analyzed using ArcMap software. The results of the GIS data analysis were compared with the data of field studies. Over the past 20 years, along the channel, changes have been observed on the right bank, filling a part of the left bank with sediment particles, germination of moisture-loving plants and the process of erosion of the left bank. Over the past 5 years, about 30 meters of irrigated areas have eroded along the right bank between pickets PK3 and PK4. These changes average 5-6 meters per year. An analysis of the deformation processes occurring in the Sokh channel is carried out and conclusions are drawn.
