Calculation of Hydraulic Mean Depth:
1. Given Data:
- Channel velocity (V) = 0.88 m/sec
- Silt factor = 1.1
2. Formula for Hydraulic Mean Depth (H):
H = A/P
where A is the cross-sectional area of flow and P is the wetted perimeter
3. Formula for Cross-sectional Area (A):
A = V * H
where V is the velocity and H is the hydraulic mean depth
4. Formula for Wetted Perimeter (P):
P = A/H
where A is the cross-sectional area and H is the hydraulic mean depth
5. Calculation:
- A = V * H
= 0.88 * H
- P = A/H
= (0.88 * H) / H
= 0.88 m
6. Since the silt factor is 1.1:
- Hydraulic mean depth (H) = P / 1.1
= 0.88 / 1.1
= 0.8 m
7. Therefore, the hydraulic mean depth is:
- 0.8 m
8. Conclusion:
- The correct option is (c) 1.76 m

= 0.88 m
6. Since the silt factor is 1.1:
- Hydraulic mean depth (H) = P / 1.1
= 0.88 / 1.1
= 0.8 m
7. Therefore, the hydraulic mean depth is:
- 0.8 m
8. Conclusion:
- The correct option is (c) 1.76 m
