Requested move 9 April 2015 

:Dnieper River →  – Per WP:COMMONANME and WP:NCRIVER. "Dnieper" is more commonly used name for the river than "Dnieper River" ("Dnieper" redirects here, so the word "river" is not useful for disambiguation neither). It's hard to use Google Search to prove this (because the string "Dnieper River" contains the string "Dnieper"), but it still might be useful to say that Google Books search returns 37.900 hits for "Dnieper River" and 319.000 for "Dnieper -River".
