NUMERICAL MODELLING OF HEAT AND WATER TRANSFER IN PERMAFROST-DOMINATED WATERSHEDS
International audience This chapter deals with the thermo-hydrological determinants of weathering fluxes in boreal watersheds, and with the insights on this matter that may be expected from a mechanistic modelling approach.
