5203 |a"Using theoretical and dimensional analysis together with available experimental data, several methods of partitioning the total shear stress exerted by open channel flow over a bed composed of triangular elements have been examined. It has been shown that the concept of isolated roughness flow is valid. Analysis indicates that partitioning is most readily accomplished by using the slope separation method when sand wave steepness is less than 0.07. When the steepness is greater than 0.07 the slope separation method can be used with an adjustment factor. The effective shear stress due to the form roughness of bedforms can be computed using principles of energy losses due to the sudden flow expansion immediately downstream of the crest. Further tests over a wider range of flow conditions are required to confirm present results for general application"--Abstract, page iii.
