Hydrology of subarctic Canadian shield: soil-filled valleys

The Canadian Shield landscape includes bedrock uplands and valleys infilled with soil. A site near Yellowknife in subarctic Canada was studied to elucidate the hydrological behaviour of soil-filled valleys. A suite of hydrological processes was found to be important in the studied valley, including snowmelt and rainfall, ground frost development, evaporation, infiltration, lateral inflow from adjacent uplands, and surface and subsurface flows. …
