Study Leader, Ecosystem and Climate Impacts of Extreme River Ice Jams and Floods
Current research and/or projects
Contributing to Environment Canada’s mandate to conserve and protect aquatic ecosystems
- Effects of climate on ice-jam flooding of the Mackenzie Delta, a key mechanism for the replenishment of delta habitats and sustenance of the delta ecosystem
- Hydroclimatic impacts on the frequency of ice-jam floods in regulated northern rivers and ecological implications to the Peace-Athabasca Delta
- Climatic controls and ecosystem impacts of ice-jam flooding in major New Brunswick Rivers
