Answer 1

The correct answer is (c) The Water Level of Distributary – Water Level of Water Course

Best explanation: HL is defined as the difference in the water levels between distributary channel and the water course. HL in design is taken as equal to the average of head loss values observed once a fortnight throughout the season. Mathematically it is defined as (H – d).
