This knowledge gap limits the development and evaluation of numerical models that aim to capture cutoff dynamics at large spatial scales. Using satellite images from 1984–2021, we identified 1,132 cutoffs across single-threaded channels wider than 90 m. We find that cutoff types are unevenly distributed across the basin: neck cutoffs (n = 594) dominate low-slope floodplains, while chute cutoffs (n = 456) are more common in steeper regions. Bimodal distributions of cutoff geometries indicate fundamentally different processes associated with neck and chute cutoffs. We introduce a mechanistic framework that includes impacts of local floodplain topography, discharge, and landcover on cutoff types. Data reveal that floodplain slope is a first-order control on cutoff type. The planform geometry of chute cutoffs is more scale-free than necks. This basin-wide perspective illustrates how cutoff type changes systematically across the Amazon, suggesting that floodplain attributes related to lentic habitat availability. More broadly, these observations provide data-driven constraints that can inform the representation of cutoff processes in morphodynamic models.<br /> }}<br /> {{blank line template}}</div>
