Dynamics of river ice jam release

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.

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 … WebDec 1, 1993 · As a result, the time and location of ice jam initiation can not be determined. Recently, Shen et al. (1990) developed an analytical framework for dynamic ice transport and jam initiation in rivers. The basic concept of river ice dynamics is similar to that of sea ice and lake ice (Hibler, 1979; Wake and Rumer, 1983). dickies pacific coveralls https://quingmail.com

WebMar 1, 2016 · The release of a river ice jam can lead to rapidly rising water levels and a fast-moving torrent of water and ice that can threaten riverside communities. Two phases are released when an ice jam fails: a water wave and a moving ice accumulation (called an “ice run”). The propagation of the water component of an ice jam release wave is … 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 … WebFeb 1, 2024 · An ice jam is a large, jumbled accumulation of broken river ice that partially blocks a river channel, raises water levels, and potentially causes flooding.
