Dynamics of river ice jam release

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 …
