| Résumé | Many hydraulic models for river ice have been developed over the past several decades (e. g., CRRISP1D/2D, RIVICE, ICEJAM, MIKE-Ice, River1D/2D, JJT, VARY-ICE, …). Their purposes were to improve our understanding of river ice phenomena and better anticipate their timing, extent, and flood risks over the short term (for operational purposes) and the long term (in the context of a changing climate). Twenty-five such models are briefly described in this paper, with information on the processes that are captured by each model, their application (usage), whether or not they are in the public domain, and sources for more information. The processes are divided into various classes: water cooling, frazil ice generation, border ice, anchor ice, ice cover formation, thermal growth and decay, ice cover break-up, ice dynamics for ice jamming/bridging, and water seepage through the keel of the ice jam. Most models are one-dimensional, i. e., they do not account for variations along channel width or depth. Model performance is not discussed – the intent of the article is, instead, to report on the variety of models described in the river ice literature and provide the readership with a summary of what they are. |
