As climate changes continue to affect permafrost regions through changing meteorology and permafrost thaw, knowledge of permafrost hydrology and hydrogeology interactions is rising in importance as it is increasingly required to address Northern Canadian needs and issues. Cold regions hydro(geo)ology is a relatively nascent, but growing field of research, and a major gap is that no comprehensive view exists of the relationships between permafrost and hydrogeology across Canada’s permafrost landscapes. Consequently, it is difficult to extrapolate documented responses of these systems to climate change and other stressors. In order to stimulate research concerning permafrost and hydrogeological interactions in Canada, the CGU Hydrology Section’s Committee on Permafrost – Hydrogeology Interactions is inviting presentations that summarize research of 1) permafrost hydrological and hydrogeological processes and how these processes manifest in different permafrost landscapes; 2) how hydrology and hydrogeology regimes across different permafrost regimes respond to climate change and other stressors; 3) how this may impact water quality and contaminant transport; 4) innovative approaches to field observations and modelling permafrost – hydrogeological interactions; and 5) the application of research to address issues caused by changing northern permafrost.
