| Abstract: | The mechanical essence of slope surface scouring is the stability of s oils and the process of hydrodynamic action of slope surface flow on soils. From the viewpoint, the forces acting on soils, flow energy and its balance during t he process of slope surface scouring are studied . Through incipient motion drag force, it obtains the occurring conditions of scouring. And it provides an engi neering illustration. |
