The 2013 Alberta Flood: Causes and Consequences

Explore the causes and consequences of the 2013 Alberta Flood in this 38-minute lecture from the Royal Tyrrell Museum Speaker Series. Delve into Jon Noad's analysis of why the flood occurred, its impact on specific settlements, and the geological evidence left behind. Gain insights into the Bow River Basin, the role of the jet stream, and the formation of debris flows. Examine case studies from Canmore and Calgary, including unseen aerial footage. Learn about sedimentological concepts such as crevasse splay deposits and river bend erosion. Compare the 2013 flood with historical events and discuss potential preventive measures for future floods. Understand ongoing monitoring efforts and draw conclusions about flood management in Alberta.
