Summary: Ice gauges are installed on river ice once the ice is strong enough to support researchers (20 gauges in the Mackenzie Delta and 15 gauges on Hay River). The gauges are read every 10 days to obtain total ice thickness, white ice thickness and snow depth. From these data, the rates of ice growth and decay can be calculated, and the approximate date of maximum ice thickness can also be determined....

Summary: The researchers will gain a better understanding of permafrost conditions of the study area and the environmental conditions under which permafrost formed and evolved. They will also investigate icings and icing processes, since icings are a hydrologic phenomenon and their occurance has implications for recharge and runoff of drainage systems and water resource management....

Summary: Spring breakup in Northern Rivers are often associated with record water levels and often lead to flooding. Present methods of forecasting the severity of these events are hampered by lack of understanding. The acquired knowledge and understanding obtained from these studies will be applied to the enhancement of suitable models for predicting the time and magnitude of these events....

Principal Investigator: Davison, D.M.
Licensed Year(s): 1975
Summary: (1) To gather field data in order to assess drainage and erosion control and to evaluate the stability of slopes along the proposed Foothills Pipeline and at key river crossings; (2) To gather subsurface soil and ice information to analyze typical slope conditions for pipe support designs for Foothills Pipeline Limited....
