this is not quite true. In Czech Republic I know a lot of places where
historically the boundary was defined by a small stream or river. The
course of the stream or river has changed, but the administrative
boundary stayed at the old place.

AFAIK even parts of country boundary that are defined by international
treaties as going by the centerline of a river are in fact fixed at a
given place and periodically reviewed and renegotiated to reflect
possible environmental changes.
