Objective(s): This study is a continuation and expansion of two previous studies on extreme flooding and deep scour holes along the Mackenzie River. The objectives of this research are to 1) quantify the frequency and magnitude of ice jams at the confluence of the Mackenzie River and Arctic Red River and downstream on the delta channels, 2) determine the hydroclimatic conditions controlling the occurrence of ice jams and associated floods, as well as the source areas of spring flooding, 3) develop/calibrate a hydraulic model of ice jamming for the Mackenzie Delta, and 4) investigate the importance of deep scour holes, which can be up to 30 m deep or 5-6 times the average channel depth. This project will help guide future research of climate change impacts and adaptations for the Mackenzie Delta region. The present field study site is on the East Channel of the Mackenzie River, on navigable waters / ice road at the boundary of the Inuvialuit Settlement Region and the Gwich'in Settlement Area. The researchers will consult the communities if/when new field study sites are added to the project.
