| Abstract: | The study on the bed shear stress of the rill obtained a threshold cross-sectional equation and discussed the changes of hydraulic geometry properties of the threshlod cross-section under the condition of critical incipient motion on the periphery of the rill. Furthermore,the soil erosion of the slope was analysed by means of the rill density. |
