Ariver icebreaker is anicebreaker specially designed to operate in shallow waters such as rivers andestuaries, and often able to pass through canals and under bridges.[1] As published by the American Society of Civil Engineers in 1916, "On some rivers, particularly where melting first takes place on the upper river, as on theOder andWeichsel 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 thenuclear-powered shallow draft icebreakersTaymyr-classVaygach andTaymyr,[4] are also in service in the large rivers of the Russian arctic.
The oldest river icebreaker in the world that is still in service is theKuna.

...the work which an Arctic ship has to do is not principally that of breaking up one season's ice, as is done by harbour and river icebreakers, in Canadian and Russian waters for instance.
