13. Design the most economical trapezoidal section to carry 35
m3 /s on a slope of 1 in 5000. Assume side slopes to be 2 H: 1 V
and 𝑛 = 0.013.
14. The area of cross-section of flow in a channel is 6 m2 .
Calculate the dimensions of the most efficient section if the
channel is (a) triangular, (b) rectangular and (c) trapezoidal (2
H: 1 V). Which has the least perimeter?
