Abstract

Physical modelling experiments have been carried out in a cold room to test on a small scale, the effects of water supply during the thaw of an experimental slope with permafrost. Permafrost was maintained at depth and a thin active layer was frozen and thawed from the surface. Data from the experiments relate to 2 different conditions, first with moderate rainfall, and second with heavy rainfall during the thaw period. These experiments provide detailed data that could improve the knowledge of the physical parameters that control the initiation, at a small-scale, of erosion processes on periglacial slopes wich are strongly dependent on climate conditions and particularly on climate warming that the AA. introduce indirectly by increasing the water supply
