  "abstract": "In periglacial environments, water flowing on the surface of frozen ground can either thermally erode the soil or form successive ice layers with not only the water temperature as a controlling parameter. This study investigates the mechanism of water flows on permafrost creating thermal erosion or ice aggradation in periglacial environments. Our experimental setup mimicked the natural occurrence of meltwater flow over permafrost terrain during seasonal transitions in early spring. Our objective was to test different scenarios defined by different boundary conditions (water discharge, water stream temperature and frozen soil temperature). This study measured thawing and erosion depths with sensors and laser, revealing that water thermal gradients control heat propagation in the thawed substrates. Results show that water temperature is the key factor: stream temperature above +1.3°C leads to erosion, while lower one (< 1.3°C) favours ice aggradation. Stream discharge rate controls thermal exchange, with low flows promoting freezing and high flows enhancing erosion.",
