Changing controls of soil water retention in an alpine catchment: Integrating sedimentological and pedological processes

•SWR was examined in soils derived from different sediments in an alpine watershed.•SWR is controlled by SOC for aeolian sediments and by PSD for fluvial sediments.•SOC enhances plant-available water capacity for sandy soils but not for silty soils.•The mattic surface soil horizon has a high functio...
