Zusammenfassung:	The invention provides a slope surface thin-layer water flow velocity correction coefficient prediction method and device. The method comprises the following steps: laying an earth surface coating at the bottom of an inclined washing water tank, and simulating the natural slope surface coating condition; adjusting the inclination angle of the scouring water tank, and simulating the gradient of a natural slope surface; providing stable water flow for the scouring water tank, wherein the water flow parameter value is adjusted to the test target flow; measuring the surface flow velocity and the water depth of the thin-layer water flow in the scouring water tank, and further calculating the submergence degree of the thin-layer water flow in the scouring water tank to the surface coating, and the average flow velocity, the Reynolds number and the correction coefficient of the thin-layer water flow in the scouring water tank; according to the submergence degrees, establishing slope surface thin-layer water flow vel
