Fig. 3: Mean monthly river discharge against mean monthly DWSA.
From: Current availability and distribution of Congo Basin’s freshwater resources

Mean monthly river discharge Q against mean monthly drainable water storage anomaly (DWSA = TWSA − WWSA − LWSA) (thin gray curve with colored disks) and time-shifted drainable water storage anomaly (thicker black curve). Mean monthly discharge values are obtained from discharge time series available over different time periods (see in S2). DWSA mean monthly values were obtained from time series from 2002 to 2015 for Kasaï, Lualaba South, and Congo, and 2002 to 2017 for the other sub-basins. The arrows represent the annual behavior of the runoff-storage relationship.
