Objective(s): The objective of this research is to study ice processes on the Hay River in order to develop computer models to predict them, addressing local issues (effects of berming and channel infilling on ice jams) and potentially providing flood warning tools, as well as exploring the impacts of development and climate variability on the frequency and severity of ice jams.

Project Description: The objective of this research is to study ice processes on the Hay River in order to develop computer models to predict them, addressing local issues (effects of berming and channel infilling on ice jams) and potentially providing flood warning tools, as well as exploring the impacts of development and climate variability on the frequency and severity of ice jams.

The progression of river ice breakup will be documented from small aircraft and from the ground. In March the river ice thickness and snow depths in the region will be measured. An Acoustic Doppler Current Profiler (ADCP) will be used to measure the river discharge. Temporary plywood targets (4’x4') will be set up along the river to serve as visual reference points in photographs. These will be removed immediately after breakup. Water and ice levels will be measured before and after ice movements, with standard survey instruments (surveyor's rod and level, total station and GPS). Similar measurements will be conducted during freeze-up, from Mid-October through mid-December.

A local guide from the Kátl`odeeche First Nation will be hired to assist with this work. Members of the community will be invited to accompany researchers on observational flights and in the field documenting breakup, and to provide input to the study on issues to be incorporated into the research.
Results will be communicated through meetings, presentations and reports. Copies of reports will be offered to ARI library.
Fieldwork will be conducted from March 01 to 31, April 14 to May 16, and November 01 to December 12, 2008 along the Hay River from approximately Enterprise (60° 33' N, 116°08'W) to the Town of Hay River (60° 49' N, 115°47'W).
