In the Arctic and subarctic, hydrogeological processes are rapidly changing due to accelerated climate change. Coastal systems are particularly vulnerable to climate-induced change due to added boundary condition changes (e.g., sea level and sea ice). The objective of this study is to investigate the impacts of sea-level rise and land surface warming on coastal permafrost extent and land-sea water exchange. This will be accomplished through the development of new process-based models.
