Short summary
In meandering rivers, flow and sediments are carried in a single thread whereas in braided rivers they are carried through numerous threads. The geometry of single-thread follows scaling relationships with discharge. The most famous of these, "Lacey's law", states that a river's width scales with the square root of its discharge. We here show that threads from braided rivers also accord with Lacey's law, and that the geometry of meandering and braided threads cannot be differenciated.
