The River Tame, in North Birmingham and in the urban areas north of
the city, has several sections, some concrete-sided and some looking
entirely natural, that are nowhere near its original course.

Indeed, one natural-looking section runs through what is in effect a
giant pond-liner, keeping it separated from the groundwater, which is
poisoned by heavy metal as the result of past industrial activity.
