Conclusion
As a result of processing of the test data for distribution of the averaged velocities, a method has been proposed for determining the zero plane of reckoning in channels with ribbed bottom roughness and recommendations are given for correction of the absolute bottom roughness obtained by the traditional mean-volume method.
