| Abstract |
Unsteady flows were generated over smooth and rough, wavy beds in a wind tunnel with the section of 80cmx80cm and length of 820cm. Seven waves were placed in the tunnel and the! measurement was carried out, over the sixth bed. Longitudinal and vertical velocity components were measured with a X-type hot-wire anemometer at 9 sections over the wavy beds. For all the sections, the velocities were taken from the bed surface to the top of the tunnel. At each point, the measurements were repeated 5 times. The large volume of data obtained are used to calculate the ensemble-mean velocities as well as the Reynolds stresses.
