Phys. Rev. Lett. 83, 3956–3959 (1999)Braided Rivers and Superconducting Vortex AvalanchesReceived 21 January 1999; revised 30 August 1999; published in the issue dated 8 November 1999 Magnetic vortices intermittently flow through preferred channels when they are forced in or out of a superconductor. We study this behavior using a cellular model, and find that the vortex flow can make braided rivers strikingly similar to aerial photographs of braided fluvial rivers, such as the Brahmaputra. By developing an analysis technique suitable for characterizing a self-affine (multi)fractal, the scaling properties of the braided vortex rivers in the model are compared with those of braided fluvial rivers. We suggest that avalanche dynamics leads to braiding in both cases. © 1999 The American Physical Society URL:
