Avulsion and anastomosis in the panhandle region of the Okavango Fan, Botswana
GPS water-surface evaluation data from the panhandle region of the Okavango Fan show that a prominent anastomosed reach occurs within a relative valley-gradient depression inferred to represent a small graben structure. Neotectonic movement, although involving only slight displacement, is seen to be the underlying cause of avulsion, anastomosis, and certain channel pattern changes in the Okavango panhandle.
