Canmore’s Rocky Mountain Outlook has published an article describing interesting research by CH PhD candidate Nic Leroux and director Dr John Pomeroy. They have been exploring how rain which falls on late-season snowpack finds its way to the underlying surface, and their experiments have shown how this happens primarily along preferential flow paths or ‘flow fingers’. This holds great promise for improving understanding of the processes involved in rain-on-snow events, which have been occurring more frequently in the Alberta Rockies over recent years, and played a major role in the floods of 2013.
