A weir accross an alluvial river has a horizontal floor length 60m and...
Given:
- Weir across an alluvial river
- Horizontal floor length of the weir = 60m
- Water retained under full reservoir condition = 6.5m
- Downstream sheet pile driven to a depth of 6.5m below average bed level
To find:
- The exit gradient for this case
Solution:
1. Definition of Exit Gradient:
The exit gradient is the slope or gradient of the hydraulic gradient line in the downstream direction of a flow system. It is a measure of the rate of energy loss in the flow.
2. Calculation of Exit Gradient:
The exit gradient can be calculated using the following formula:
Exit Gradient (E) = (H1 - H2) / L
Where,
H1 = Headwater level (water retained under full reservoir condition) = 6.5m
H2 = Tailwater level (sheet pile driven to a depth of 6.5m below average bed level) = 6.5m
L = Length of the weir = 60m
Substituting the given values into the formula:
Exit Gradient (E) = (6.5 - 6.5) / 60
= 0 / 60
= 0
3. Interpretation of the Result:
The calculated exit gradient is 0. This means that there is no energy loss in the flow, and the hydraulic gradient line is horizontal. In other words, the water flows smoothly without any significant change in energy level.
4. Conclusion:
The exit gradient for this case is 0, indicating no energy loss in the flow.

Substituting the given values into the formula:

= 0 / 60
= 0
