matthen:

The meanderiness of a river, its Stølum number, is defined as the length the water travels from source to finish (blue curve) divided by the direct distance (red line).  This can change chaotically as a river changes coarse, forming Ox bow lakes. The ratio is often found to converge to (but rarely exceed) 3.14, roughly pi. [more] [code] [thanks] [thanks2]
