Abstract: Measurements of annual pore-water pressures and temperatures in a well-drained lowland and a tussock suprapermafrost soil indicate a complex sequence of events with the most dynamic and significant behavior occurring in the winter months. Vertical water movement in the soil profiles during the summer months is negligible, the well-drained soil being unsaturated and the tussock soil being water-logged. The presence of a water table in the well-drained soil promotes warmer winter soil. The absence of a water table in the tussock soil, underlain by a shallow ice-rich permafrost table, promotes complete freezing of the soil, drying it and causing low pore-water pressures and reducing the hydraulic conductivity.
