THERMAL AND HYDROLOGICAL EFFECTS OF SLOPE DISTURBANCES IN A CONTINUOUS PERMAFROST ENVIRONMENT

In a wntinuous permafrost area near Resolute, N.W.T. a berm, a trench and an impermeable subsurface flow barrier were emplaced across a slope, and compared with two undisturbed segments. These plots enabled the observation of thermal and hydrological effects of these disturbances in a continuous per...
