| Abstract: | Sediment delivery in rills on the loess slope was studied by inflow experiments. Relationships between sediment delivery rate in rills and flow shear stress, discharge and slope gradient, maximum sediment and unit runoff power, and discharge and slope gradient were analyzed. A relationship is presented for calculating the erosion rate in rills . |

| Keywords: | rill erosion. critical shear stress unit stream power sediment rate. |
