Floodplain significance through river basins applied to the National Hydrography Database Plus stream network. a Event floodplain inundation volume [log m3], with inset highlighting approach to estimate river-floodplain exchange per reach. b River-floodplain exchange during events [log10 m3 m−1] within all streams of order n across major river basin. The uncertainty bounds represent 95th confidence derived from the uncertainty analysis. c Cumulative annual river-floodplain exchange [log10 m3] within each stream order across major river basin
