Extended Data Fig. 5: Examples showing water occurrence and surface water connectivity over the past four decades.
From: Global net increase in surface water connectivity in river–floodplain systems
The upper panels (a, c, e, g, i, k, m, o, q, s, u, w) show water occurrence maps derived from the GSWOdataset20, and the lower panels (b, d, f, h, j, l, n, p, r, t, v, x) show surface water connectivity under normal inundation conditions for each pixel and river reach during the period 1984–2019. To quantify connectivity between the inundated surfaces within the river–floodplain and the river’s centerline, we aggregated pixel-level estimates to river reach-level by averaging the connectivity values at the central points of each river reach. These river reach-level estimates represent the primary results of our study.
