Sediment movement in a wide river is to be studied using a movable-bed model. The prototype bed is composed of equal portions of MS, CS, and VCS, and the river slope is 0.00027.
The model bed material has a specific gravity of 1.35. Determine the required model sediment sizes, the length ratios, the water discharge per unit width ratio, and the shear stress ratio.
If the depth ranges from I ft to 6 ft in the protoype channel of Prob. what is the corresponding depth range in the model?
