摘要
In this paper, the flow resistance in a flume with rough bed was studied, and the criteria of 2-dimensional flow were obtained. The effects of bed roughness on Manning coefficient n and Chezy coefficient C were also discussed, and the experimental results indicate that n and C can be taken as constants for small-scale roughness case.
