Question

What is the reason for the construction of baffle wall in baffle fall?

(a) To Maintain Uniform Velocity Flow

(b) To Ensure Formation of Jump

(c) To Reduce Soil Erosion

(d) To Ensure Uniform Discharge of the Flow

I got this question in an internship interview.

Query is from Canal Falls in section Canal Falls of Irrigation Engineering

Answer 1

Right answer is (b) To Ensure Formation of Jump

The explanation is: The baffle wall is provided at a calculated height and a calculated distance from the toe of the glacis to ensure proper formation of the jump on the baffle platform. This type of fall is suitable for all discharges and for drops which are more than 1.5 m.
