Summary:
It is known that extreme flood levels within the Mackenzie River Basin are caused by ice jamming events. Analysis of open water versus ice influenced water levels at several sites within the Mackenzie River Basin will provide further quantification of th...

Summary:
The objective of the research is to supplement and extend instrumental climatological and hydrological records in the NWT using dendrochronology (tree-ring) and varved lake sediment analysis. Transportation to the site will be by charter aircraft from Fo...

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 purpose of the project is to improve the ways we have to predict the spring floods in the smaller rivers. Floods from snowmelt are a particular concern in northern rivers. In the Ft. Simpson area, spring flows from the smaller rivers, which are tributaries to the Liard and Mackenzie, have a great deal to do with the timing and nature of breakup on the major rivers. Snow conditions will be surv...

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....
