Ice jam

Ice jam on the Danube River at a bridge in Vienna, Austria

Ice jams occur when a topographic feature of the river causes floating river ice to accumulate and impede further progress downstream with the river current.[1] Ice jams can significantly reduce the flow of a river and cause upstream flooding—sometimes called ice dams. Ice jam flooding can also occur downstream when the jam releases in an outburst flood. In either case, flooding can cause damage to structures on shore.
