$6.$ Muskingum Stream Routing. Problem $9\mathrm{.}3\mathrm{.}5$ in Mays's book $($Water Resources Engineering$).$ Plot the inflow and outflow hydrographs. If you do not have the book, I pasted it here: $(10$ Points$)$

$9\mathrm{.}3\mathrm{.}5$ Route the following upstream inflow hydrograph through a downstream flood control channel reach using the Muskingum method. The channel reach has a $K=2\mathrm{.}5hr$ and $x=0\mathrm{.}2.$ Use a routing interval of $1hr.$

Hint: Answers to first $3$ steps provided below. If you choose to do it by hand, do the $4$th to $10$th steps.
