Peat hydraulic conductivity in cold regions and its relation to pore size and geometry

Abstract Subsurface flow through peat plays a critical role in the hydrology of organic‐covered, permafrost terrains, which occupy a large part the continental arctic, sub‐arctic, and boreal regions. Hillslope drainage in these terrains occurs predominantly through the active flow zone between the relatively impermeable frost table and the water table above it. The hydraulic conductivity profile within this zone controls the subsurface …
