Corporate name Deltares Project Kustgenese Date 1997-10-01 Abstract Previous measurements (e.g., Klopman, 1994) have shown that in the centre-line of the flume the mean horizontal velocity profile in waves fol/owing the current bends back in the upper region of the water column compared to the current alone case. For waves opposing the current the opposite behaviour was found . In order to explain this behaviour Radder (1994) suggested the Craik-Leibovich (ell vortex-force mechanism. This hypothesis was successfully simulated numerically by Van Kester et al. 119961. However, the explanation of the mean horizontal velocity-profile changes by the CL vortex-force mechanism depends essentially on secondary circulation cells in the transverse cross-section of the flume . To test the existence of these secondary ci rculation cells in a laboratory wave-current flume, additional measurements have been performed in the present project. It was found that these secondary circulations are clearly present in the flume as well.
