This study presents a unique multi-tool dataset on riverbank migration across Northern Eurasia, covering 140 000 km of river channels over a period of up to 70 years. Using satellite imagery and field observations, we identify key drivers of bank erosion at a large spatial scale and highlight the role of river discharge and permafrost. The dataset enhances understanding of river channel dynamics and supports the development of predictive models for river channel evolution and erosion risk assessment.
