please solve this problem ASAP I am struggling with it$.$A $5-$ft$-$wide rectangular channel has a slope of $s_0=0\mathrm{.}001$ and is made of asphalt. Given a

flowrate of $Q=9cfs$ in the channel and a depth of $4ft$ at location $($a$),$ determine the flow profile

and sketch the profile $($be sure to include normal, actual, and critical depths in the profile$).$ You

may use a numerical solver such as wolfram alpha, a calculator solver, or graphical methods to

solve for $y_0.$ Be sure that you show the simplified equation and all of your work for the

calculation.
