Question

Design a distributary head regulator for the following data:

Table:

- Full supply discharge (cumecs): Parent channel = 100, Off-take channel = 15

- Full supply level (m): Parent channel = u/s = 218.10, d/s = 217.90; Off-take channel = 217.10

- Depth of water (m): Parent channel = 2.5, Off-take channel = 1.5

- Bed width (m): Parent channel = u/s = 42, d/s = 38; Off-take channel = 15

Take safe hydraulic gradient as 1 in 6. Assume C₁ = 0.557, C₂ = 0.80.
