City of Oklahoma on the Arkansas River (5)

I believe the answer is:

tulsa

(Other definitions for tulsa that I've seen before include "US city" , "Major oil centre" , "Oklahoma city (only 24 hours away?)" , "Twenty-four Hours from - (Gene Pitney)" , "Oklahoman city" .)

I've seen this clue in The Times and The Sunday Times.
