Southern Alberta is no stranger to flooding, but this week's devastation from Canmore to Calgary and beyond was the result of a unique confluence of unexpected weather and a still partially frozen landscape unable to soak up the unprecedented deluge.
Hydrologists who watch the waterways like the Bow and Elbow rivers say several factors were at play since the rain started to fall about four days ago.
"To have these very large flood events ... the stars have to line up," says Uldis Silins, a hydrologist at the University of Alberta in Edmonton.
