Rivers are never straight. What makes them curvy is something I never questioned in the first place.
What’s really fascinating is, how these curves form. They are almost always in pairs, alternating curves, unless there’s some geographical feature messing with the natural flow. From a hypothetical straight line river, these curves start forming when there’s even a slight aberration in the bank.
Besides that thicker a streams make bigger curves. And smaller tributaries meander in tighter turns. This is what makes rivers (with their smaller tributaries turning tighter and bigger ones in bigger curves) look like fractals on the surface of the earth.
