International audience; In the ice-rich permafrost of the Arctic regions, thermokarst erosion on slopes induces the formation of large-scale retrogressive thaw slumps (RTS). They have significant geomorphological, hydrological and biogeochemical impa

International audience; Fluvial thermal erosion following ice breakups of the Lena River (Yakutia, Siberia) is a significant geomorphic process. During the initial stage of ice breakup, ice pushes up onto the river banks and produces large accumulati

Effects of ice content on the thermal erosion of permafrost : implications for coastal and fluvial erosion
Autor: Dupeyrat, L., Costard, F., Randriamazaoro, R., Gailhardis, E., Gautier, E., Fedorov, A.

Permafrost and Periglacial Processes, Wiley, 2011, 22 (2), pp.179-187 (IF 1.870). ⟨10.1002/ppp.722⟩
International audience; The effects of ice content and water flow on thawing and erosion of non-cohesive permafrost banks were investigated through laboratory experiments. A critical ice content was identified as associated with turbulent flows (20%
