Permafrost and Groundwater
|
As Arctic permafrost continues to warm and thaw, how will the flow of groundwater change in cold-region settings? We use numerical models that can dynamically simulate the thawing of permafrost and groundwater to understand how climate is impact groundwater systems in cold regions. Additionally, we have an ongoing northern field sites to observe cryohydrogeology in action.
