Effects of climate variability and change on surface water storage within the hydroclimatic regime of the Athabasca River, Alberta, Canada
Warmer air temperatures projected for the mid-21st century under climate change are expected to translate to increased evaporation and a re-distribution of precipitation around the world, including in the mid-latitude, continental Athabasca River region in northern Alberta, Canada. This study examin...
