Extended Data Fig. 9: Surface water connectivity changes across different periods and inundation conditions.
From: Global net increase in surface water connectivity in river–floodplain systems
The left, middle and right panels show the change rate of surface water connectivity calculated from 1980–1990s to 2000s, from 2000s to 2010s, and from 1980–1990s to 2010s, respectively. The five inundation conditions (that is, flood, wet, normal, dry, and extremely dry) are represented within each panel by five thresholds of GSWO (that is, GSWO ≥ 1%, 25%, 50%, 75%, 95%). Within each panel, pie charts display the fractions of river length with different change directions. Regions shaded in dark gray denote areas with insufficient satellite coverage during earlier observation periods, while light gray regions indicate areas where no rivers were detected by 30-m resolution Landsat imagery.
