Abstract

In recent years investigators have given increased attention to flow in natural, high-gradient, rough, open channels. Studies include work in both the laboratory and in the field. Solutions to the problem are still incomplete; however, continued attention by investigators is needed to answer many questions. Using a laboratory flume, the writer studied one of the questions concerning the relative importance of gross velocity fluctuations versus turbulent mixing, and the ranges of each under different ranges of submergence and kineticity of flow. In the different ranges, the effect of size and concentration of the roughness elements was studied.
