Unit IV
- Q7. Design a Sarda type fall across a canal for the following data : 20 Full supply discharge U/S/d/s = 15/15 cumecs Drop = 1.0 m Full supply level U/S/d/s = 101.00/100.00 m Full supply depth U/S/d/s = 1.8/1.8 m Bed width U/S/d/s = 10/10 m Design the floor on Bligh's theory using coefficient of creep = 10. Sketch the longitudinal section of fall. [20 marks]
- Q8. Draw a neat sketch of Distributary Head Regulator and Design the crest and water way of the cross regulator for the following data : 20 Discharge of the parent channel = 100 cumecs F.S.L of parent channel : u/s = 218.10 m and d/s = 217.90 m Bed width of parent channel : u/s = 42 m and d/s = 38 m Depth of water in parent channel : u/s = 2.5 m and d/s = 2.5 m Take $C_1 = 0.557$ and $C_2 = 0.80$.
