Abstract

This paper shows the effect of thaw settlement on the thermal response of a small permafrost mound in Northern Québec to different scenarios of climate warming, with a finite-element, one-dimensional, heat conduction model. In addition to the cryostratigraphy of the mound, the unfrozen water content, thermal conductivity and volumetric heat capacity of the marine sediments comprising the mound were integrated in the simulation. Thaw settlement, the direct results of ice melting in permafrost, brings permafrost nearer to the surface and accelerates its thawing. It should be included in any numerical simulation
