Dynamics of river ice jam release
WebOct 28, 2011 · Ice jam formation and release along an ice-covered or partly covered river channel can result in a series of javes and stalls, each cycle breaking an ice-covered section, and the resulting hydraulic storage release contributing to the flow driving the breaking front progression (Beltaos et al., 1993). WebThe Alaska River Forecast Center conducts ice breakup overflights each spring to identify potential for ice jams. The information is used to supplement ground observations that are used to provide flood warnings to residents of affected villages. The methodology used in the reconnaissance and a summary of selected observations are presented.

WebThe numerical model DynaRICE and its application to ice jam formation and release is presented. The model is a two-dimensional coupled flow and ice dynamic model. The ice dynamic component, which includes both the internal ice resistance and boundary friction on ice motion, uses a Lagrangian SPH method. The hydrodynamic component of the model ... 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 ...
