Which parameter plays a crucial role in determining the design discharge for a canal in both alluvial and non-alluvial soils?
27. Which parameter plays a crucial role in determining the design discharge for a canal in both alluvial and non-alluvial soils?
- Bed slope
- Soil permeability
- Sediment transport capacity
- Channel cross-section shape
Answer
The correct answer is: A) Bed slope
Explanation
Bed slope dictates the hydraulic gradient and thus influences the design discharge capacity of the canal, regardless of soil type.
