Elevation changes and available streamflow data in the southern Andes. (A) Variations in elevation of the southern Andes in Chile, western Argentina and south-western Bolivia. The black area in the southwestern sector reflects the complex detail of the coastline. (B) Location of all the streamflow stations available for this study (n = 1226). (C) Selected stations in Chile, Bolivia and Argentina (n = 513). The pink shading shows the upslope area aggregated for all these selected sites. (D) Location of the reference stations representing basins with long, complete river records (n = 51; see Supplementary Table 1). The records from these reference basins were used in the assessment of spatial and temporal patterns of variations in the southern Andes (see Data and Methods for details).
