| Abstract | This paper reviews the interactions between permafrost (an aquitard) and water flow systems within discontinuous permafrost of the subarctic Canadian Shield, identifies knowledge gaps, and describes
potential consequences of changing permafrost conditions as a result of climate warming. Discontinuous permafrost in this region is in thermal disequilibrium, with frozen ground occupying small but perhaps crucial locations along the drainage
network. It is unclear how changes to permafrost-hydrogeology interactions will influence larger basin scales and cascade through subsequent environmental systems. We develop a conceptual framework of how non-linear changes to permafrost-hydrogeology
interactions may progress due to climate warming. These changes have broad implications for water resources and affect northern environments, societies, and economies. Knowledge gained from conceptual framework development is the first step towards
improving adaptation and mitigation measures to changing permafrost-hydrogeology interactions. |
| Summary | (Plain Language Summary, not published)
This paper will review the interactions between permafrost and water flow systems within discontinuous permafrost of the sub-Arctic Canadian Shield,
identify outstanding knowledge gaps, and describe potential consequences of changing permafrost conditions with climate warming. Permafrost and hydrogeological conditions are described first. Then a conceptual framework is developed for permafrost
and hydrogeological interactions in a changing climate. The framework is intended to be the first step towards understanding how changing interactions between surface and subsurface water flow pathways with climate warming will affect northern
environments, societies, and economies. This work may ultimately lead towards improving adaptation and mitigations measures to changing permafrost and hydrogeology interactions. |
