Conclusion

The authors would like to underline errors in the mean velocity measurements in previous paper (Pineau et al. 1987). The direct drag measurements and Reynolds stress data were confirmed, and the new mean velocity profiles, in conjunction with the drag data resulted in exactly the same roughness scaling function as proposed by Perry and Joubert (1963) for the same k-type roughness.
