Q2) Water is flowing in three side-by-side pipes of diameter (1.8m) each. The Manning's (n) and the bed slope of each pipe are (0.017) and (1:1000) respectively. The water depth in each pipe is (1.6 m). After the development, the discharge above is expected to increase by (25%), and the engineers have decided to replace the three pipes by a trapezoidal channel. The new channel should have (n= 0.013) with the same bed slope ,B = 1.15 y, and z=1. Design the cross section of the new channel.

Drainage of Pavements

Pavement Drainage holds ample significance, as it prevents the accumulation of water or any liquid on the surface of pavements and ensures proper drainage system. With proper design and gradual slopes provided, the water gets easily removed from the surface into the drains, which are essential during heavy rains and unusual weather conditions keeping it less prone to accidents and increasing the durability of the pavement structure.

Question

Q2) Water is flowing in three side-by-side pipes of diameter (1.8m) each.
The Manning's (n) and the bed slope of each pipe are (0.017) and (1:1000)
respectively. The water depth in each pipe is (1.6 m). After the
development, the discharge above is expected to increase by (25%), and
the engineers have decided to replace the three pipes by a trapezoidal
channel. The new channel should have (n= 0.013) with the same bed slope
,B = 1.15 y , and z=1. Design the cross section of the new channel.
