Extended Data Fig. 6: Relationship between water-to-basin area ratio and connectivity for global level-3 river basins (sample size = 197).
From: Global net increase in surface water connectivity in river–floodplain systems
The water-to-basin area ratio is calculated by dividing the surface water area within river–floodplain systems by the total area of the basin. Data points represent the length-weighted mean connectivity of river reaches within each river basin under normal (GSWO ≥ 50%) conditions. Dots with black outlines correspond to the 26 largest river basins. Error bars indicate the variability in water-to-basin area ratio and connectivity under dry (GSWO ≥ 75%) and wet (GSWO ≥ 25%) conditions, providing insights into how water availability and connectivity vary across different climatic conditions for each individual basin.
