The ephemeral gully erosion was an important issue and had great distribution in the Loess Plateau.The runoff and sediment from up-slope had great impacts on slope soil erosion.In this paper,its effect on down-slope ephemeral gully erosion sediment yield and hydrodynamic parameters were analyzed by water discharge scouring experiments in fields,with the designed discharge 5 L/min,10 L/min and 15 L/min on the slope of 26°.The results indicated that the runoff from up-slope increased the flow velocity.The Rey...
