Physical modelling has been developed in order to simulate the effects of periglacial erosion processes on the degradation of slopes and scarps. Data from 41 experimental freeze-thaw cycles are presented. They attest to the efficiency of periglacial

, to a first approximation, the annual thermal and hydrological regime of permafrost in bedrock. Some preliminary results from 3 cycles of freezing and thawing are discusses in order to demonstrate the potential of this new approach to periglacial weathering
