Soil and organic carbon redistribution in a recently burned Mediterranean hillslope affected by water erosion processes

•SOC content was homogenized at hillslope positions in burned Mediterranean soils.•Burned soils have different distributions of aggregate mass (size and density) and SOC (density).•Four rains mobilised high sediment and SOC amounts (role of soil erosion as C sink).•OC was initially transported as non-protected (FLF > OLF > HF) and later as protected (HF > FLF > OLF).
