Since we are supposed to use British English, I decided to look up wadi in my old paper edition of the Oxford English Dictionary (can we trust that more than Wikipedia?):
"Wadi or Wady [Arabic: وادي wādī] In certain Arabic speaking countries, a ravine or valley which in the rainy season becomes a watercourse; the stream or torrent running through such a ravine." Apparently first used in English literature in 1839 by the way. So it seems it could either be the valley or the actual intermittent watercourse. In that respect the term "wash" in the U.S. southwest is more specific as it is only applied to the intermittent watercourse. My impression from Southern California is that arroyo can be the valley/ravine as well as the actual watercourse, so that might match the OED definition of wadi more than "wash" does.
