The Eisbär, a German riverine icebreaker.

A river icebreaker is an icebreaker specially designed to operate in shallow waters such as rivers and estuaries, and often able to pass through canals and under bridges.[1] As published by the American Society of Civil Engineers almost a century ago, "On some rivers, particularly where melting first takes place on the upper river, as on the Oder and Weichsel in Germany, the formation of ice jams is a frequent cause of floods."[2] River icebreakers can operate in any navigable waterway to prevent such ice jams.[3]

Various river icebreakers, from smaller vessels to nuclear-powered shallow draft icebreakers Vaygach and Taymyr,[4] are also in service in the large rivers of the Russian arctic.
