Question

A trapezoidal channel 4m bottom width and 21 side slopes is laid to a bed slope of 1
in 4900. The channel camies discharge of water at a critical slope of 1 in 200 and
normal depth of 1m under critical condition. At a certain section if the depth is 2m
determine the length between 2m depth and normal depth Take Manning's roughness
coefficient as 0 02​
