Fig. 2From: Greater Alpine river network evolution, interpretations based on novel drainage analysisAlpine χ-map with a base level of 250 m a.s.l. White lines refer to the main river catchment outlines. Values of χ can be interpreted as expected elevation at equilibrium under constant uplift and climate conditions (see text). Very high χ-values are observed in the headwaters of the Inn and the Lech, which are the major Alpine tributaries of the DanubeBack to article page
