This article analyzes the morphological changes, erosion, and accumulation processes occurring in the Qoradaryo River. The study is dedicated to one of the major issues, bank erosion, under the influence of river flow, sediment deposition, and alterations in the shape of the riverbed. The authors used Sentinel-2 satellite imagery obtained from 2018 to 2024, along with hydraulic and hydrological data collected under field conditions. These datasets were analyzed using the ArcGIS software and the NDWI index to identify changes in water level and flow direction. Within the framework of the study, hydraulic parameters of the flow were measured at 12 characteristic cross-sections using a Doppler device, and turbidity was analyzed in laboratory conditions using a spectrophotometric method. Additionally, the fractional composition of suspended sediment particles was studied using the aerometric method. Based on geomorphological analyses, the surface area and volumetric indicators of eroded and accumulated zones were calculated. According to the study results, zones with high erosion risk and relatively stable areas were identified, and corresponding protective measures- biologically and engineering approaches were recommended. The article highlights the advantages of an integrated analysis approach combining remote sensing and field data.
