Show me the steps to solve b$)$ To mitigate the flooding problem in Sungai Penchala, an Engineer decided to change the

natural river into a rectangular concrete channel. Devise for the river routing using the inflow

hydrograph tabulated in Table Q$5($b$).$ Given that $K=1\mathrm{.}2$ days, choose an appropriate value

of the relative weight, $x$ for both rivers. Use a routing period $t=1$ day and assume that the

inflow equals the outflow for the first day. Determine if the river modification efficient to

reduce the flooding. Illustrate in terms of outflow calculated using Muskingum method.
