A physical model was developed to study the wind-driven current in laboratory under the conditions of different wind velocities and different slopes. The wind-driven current in the laboratory was extensively measured by particle image velocimetry (PIV) and accurate field information was got. Furthermore, three-dimensional numerical simulation of the wind-driven current was carried out and the result showed the applicability of the physical model. The results showed that the experimental facility was easy to operate and wind field was stable. The results were accorded with the water body motion law in the wind driven current.
