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?

1. Bed slope
2. Soil permeability
3. Sediment transport capacity
4. 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.
