Girl comes a cropper in Zambia (8,5)

I believe the answer is:

victoria falls

'in zambia' is the definition.
('Victoria Falls' is part of 'zambia')

'girl comes a cropper' is the wordplay.
'girl' becomes 'victoria' ().
'comes a cropper' becomes 'falls' (I've seen this in another clue).
'victoria'+'falls'='VICTORIA FALLS'

(Other definitions for victoria falls that I've seen before include "Current attraction" , "Zambezi cataract" , "Zambezi River spectacle" , "Tourist attraction of the Zambezi" , "drop of water" .)

I've seen this clue in The Globe and Mail.
