translate English to French: Frozen soils affect surface runoff, infiltration, snowmelt, ground water flow, evaporation and transpiration, and hence hydrologists are also interested in soil temperatures.
Le gel du sol modifie le ruissellement de surface, l'infiltration, la fonte des neiges, l'Ã©coulement souterrain, l'Ã©vaporation et la transpiration; c'est pourquoi la tempÃ©rature du sol intÃ©resse aussi les hydrologues.
