There are striking similarities between the structure of natural river networks and others found in systems as diverse as brains, roads and the communication technologies. Using a series of examples, the authors illustrate how a suite of graph theory-based metrics derived from diverse disciplines can be used to provide new insights into the structure and kinematics of braided river networks.
