Landscape evolution model linking land cover, soil landscape and SOC turnover Good prediction of both sediment fluxes the SOC profiles for each land cover Modeled SOC profiles are each geomorphic position are in line with observations. C uptake balances the initial loss due to land cover change over centuries. Need to consider and accurately quantify past erosion rates to assess the SOC budget
