Manning roughness coefficients for the composite channel given below are ${}_F=0\mathrm{.}013,n_2=0\mathrm{.}017$ and $1\mathrm{.}5m$

long vegetated section has $n_5=0\mathrm{.}023.$ Calculate the discharge passing through the cross$-$section of the channel

if the channel bed slope, $S_0=0\mathrm{.}008.$ Hydrmechanics problem. Solve it numerically handwritten please with clear steps.
