4. What is the flow velocity under maximum flow conditions to the nearest tenth in m/s? 5. Determine the shear stress on the bed under maximum flow conditions to the nearest tenth of a Pa. 6. Assume the sediment on the bed has a density of 2740 kg/m³ and that the critical dimensionless Shield's stress is 0.06. What diameter sediment would be moving under the minimum flow conditions to the nearest mm?

Table 1c. Estimated Discharge and Related Errors for Max Avg Min Width, m 1650 1557 1465 Depth, m 24.0 22.7 21.4 Slope, m/km 0.035 0.032 0.029 n 0.028 0.025 0.022 4. What is the flow velocity under maximum flow conditions to the nearest tenth in m/s? 5. Determine the shear stress on the bed under maximum flow conditions to the nearest tenth of a Pa. 6. Assume the sediment on the bed has a density of 2740 kg/m³ and that the critical dimensionless Shield's stress is 0.06. What diameter sediment would be moving under the minimum flow conditions to the nearest mm? 7. Assume the river cannot get any steeper than 0.035 m/km at this location. At that slope, how deep would the flow need to become to transport grains 9.5 mm in diameter, to the nearest m?
