Vegetation affects gully headcut erosion processes by regulating runoff hydrodynamics in the Loess tableland region

•Vegetation increased the Manning roughness coefficient and Darcy–Weisbach friction factor in the upstream area.•Vegetation can increase runoff shear stress of upstream area at small inflow discharge.•The influence of vegetation with clustered stems on roughness and runoff velocity was greater than...
