FIGURE 1.

Examples of river network analogues with increasing level of resemblance with real river networks. Line width increases toward the downstream direction. (a) Linear array of patches (Vannote et al., 1980). (b) Binary‐fission‐like tree (Fagan, 2002; Paz‐Vinas et al., 2015). (c) An OCN spanning a 50 × 100 lattice, aggregated with a threshold area equal to 25 pixels. (d) A real river (Thur, Switzerland), spanning an area of 740 km², extracted from a digital elevation model with a threshold area equal to 4 km²
