Roughness Characteristics of Rock-Lined Channels
This investigation was to improve the design of rock lined channels. By an extensive review of the literature it became apparent that there exist important functional relationships between Manning's n and the Froude number, Reynolds number, relative roughness, and slope. To establish these relationships, over one hundred independent field and laboratory data-sets were subjected to statistical analysis. Results revealed that for rough channels n is influenced by the Froude number and the slope. As a consequence of these results, the maximum Manning's n for large channels specified in the ODOT Location and Design Manual was recommended to be changed from n=0.06 to n=0.04.
