Fig. 8: The distribution of stable river extent and its correlation with nighttime light intensity.
From: Satellites reveal hotspots of global river extent change

The map shows the percentage of river area with generally stable extent (PGS, %) in each level-6 basin. The top 15 countries/regions with the highest PGS and the lowest PGS among the top 50 counties with the largest river area are shown on the bottom inset. The left inset shows the PGS statistics in relation to nighttime lights for each basin where the population density is larger than 1 person/km2.
