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 … WebThe granular mass theory of river ice jams is extended to their downstream transition as a means of improving understanding of conditions at jam toe. The theory is coupled with …

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 ... 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 … WebAccounts by witnesses of spring ice breakup in rivers often mention violent ice runs with extreme water speeds and rapidly rising water levels. Such events are believed to follow the release of major ice jams. To gain preliminary understanding of this problem, an attempt is made to reconstruct a partially documented ice jam release reported recently by others. … cimarec 3 hot plate
