WebEach year, ice jams occur on many Canadian rivers, obstructing the flow and causing rapid increases in upstream water levels. Ice jams can significantly affect the river's discharge during their formation and release. However, due to safety and logistical issues, direct discharge measurements on ice jams are impractical. Also, because of the variable … Webin open, ice-covered, and partially covered by ice flows, as well as during ice jam formation under the effect of a release wave.

WebSurges or flood waves made up of ice and water resulting from the release of ice jams can be destructive to life and property and are also one of the more complicated problems in river ice engineering. The interaction between the ice mechanics and unsteady flow leads to results that are often unpredictable with open water unsteady flow models. There are … WebNov 1, 2024 · Ice jams are large chunks of floating ice that form on a river and block its flow. They occur when warming temperatures and heavy rains cause snow and ice to melt very quickly. As river waters rise, the surface layer of ice breaks into chunks that are carried downstream by the rushing waters, forcing the ice chunks to lodge against one another ... WebJan 1, 2008 · Abstract.
