Rhinos moving east away from water? (7)
I believe the answer is:
inshore
'away from water?' is the definition.
(towards the shore)
'rhinos moving east' is the wordplay.
'moving' indicates an anagram (letters are moved around).
'east' becomes 'e' (abbreviation).
'rhinos' is an anagram of 'inshor'.
'inshor'+'e'='INSHORE'
(Other definitions for inshore that I've seen before include "little out to sea" , "No heirs (anag.)" , "close to beach" , "towards the coast from the sea" , "Close to the land" .)
