Abstract:

The frictional resistance and mixing process affected by roughness bars are investigated. Specific combinations of the size and layout of the bars for various flow conditions are suggested through analyzing the scaling of friction factor, transverse mixing coefficient and longitudinal dispersion coefficient. The result agrees reasonably well with the San Francisco Bay-Delta Model.
