Focal Examination of the 2013 Extreme Weather and Flooding in Alberta
In late June 2013, intense rain fell for several days over a large area of the southern Canadian Rocky Mountain front ranges and foothills in Alberta, causing widespread flooding with severe and costly damages to many communities, mass evacuations, and loss of life. Shortly after, the Changing Cold Regions Network set out to examine the chain of events leading to this disaster, focusing on atmospheric conditions and flood meteorology, hydrological and land surface processes associated with the flood, water management and operational decision making aspects, and computer modelling and simulation of various aspects of the flood to improve future prediction of similar events.
A scientific and stakeholder workshop was held in Canmore, AB, in February 2014 to discuss various aspects of the flood and present preliminary scientific analyses, as well as to hear from local emergency response personnel and water management professionals about their experiences.
- Workshop on "Extreme Weather and Hydrology - Lessons Learned from the Western Canadian Floods of 2013 and Others" (Grande Rockies Resort, Canmore, AB, February 11-12, 2014)
An outcome of the workshop was the development of plans to organize a set of scientific papers for a special journal issue. Most of these papers have now been published in a special issue of the journal Hydrological Processes. In addition, a significant amount of media coverage focused on network member's assessments and insights on various aspects of the flood event. A lisiting of news items and interviews is provided below.
In particular, see a recent news story (Three years later, lessons being learned from the flood of 2013), and see information brochures on the changing environment of the Rocky Mountains and a brochure describing the events and the lessons learned.
