Research Project:  Hydrogeomorphic factors controlling the routing of shallow groundwater in permafrost regions.

Project Description:  Recent research suggests multiple environmental consequences of climate warming and associated permafrost degradation. The hydrologic regime of Arctic rivers and the management of water resources in northern communities are likely to be affected.  My master’s research will contribute to a collaborative research project supported by ArcticNET-NCE that will investigate environmental controls on the hydrology of the Niaqunguk (Apex) River situated near the capital city of Iqaluit, Nunavut. This study aims to advance our understanding of subsurface flow dynamics and water sources during the active layer thawing period.  The Niaqunguk River is being considered as a potential potable water source for the rapidly expanding city of Iqaluit.
