In a 1973 City of Calgary flood plain management report by Montreal Engineering Co. Ltd., estimates of flood-frequency of the Bow River upstream of the Elbow River in Calgary provided the following results: There is a 10-percent annual exceedance probability (AEP) flood or a 10-year flood return period with a peak flow or flood discharge ...
Atmospheric rivers of the sort causing massive floods and mudslides in Canada's British Columbia are akin to a river in the sky, weather systems that carry up to 15 times the volume of the ...
In fact, flooding along the Ottawa River has been recognized as the most important weather event of the year 2019 in Canada, and the one along the Saint John River as the ninth, by Environment and Climate Change Canada. [1] [2] The flooding caused by the rapid spring snow melt, coupled with frozen ground, and several heavy rain events that ...
Extreme weather in parts of Canada is causing flooding and power outages in several areas, including Toronto, Mississauga, and North Dumfries Township.
Increased water runoff due to snowmelt was a cause of many famous floods. One well-known example is the Red River Flood of 1997, when the Red River of the North in the Red River Valley of the United States and Canada flooded.

[2] Whereas heavy rain often causes a flash flood, a spring thaw event is generally a more incremental process, depending upon local climate and topography. A stream, river or flood of fresh water which empties into the ocean, usually flowing through an estuary. [3]

Canada was the world's 7th largest greenhouse gas emitter in terms of GHG Inventory data, as of 2021. [ 5 ]
Flood modelling is a tool used to model flood hazard and the effects on humans and the physical environment. [65] Flood modelling takes into consideration how flood hazards, external and internal processes and factors, and the main drivers of floods interact with each other.
