Problem $2$: Solve the above problem using NRCS TR$-55$ method. The pre$-$developed area can be considered as wooded area in fair condition. The soil type is C and average moisture conditions prevail. The post$-$developed area is impervious area with paved parking, roofs, roads, etc. The $25$year $24-$hour rainfall amount is $2\mathrm{.}72$ inches, and the rainfall distribution is of Type II$.[10]$

Hint: Find the CN values for both conditions. As average soil moisture conditions prevail, CN values are not modified $($dry or saturated condition$).$ Since there is no pond or swamp area, the pond$/$swamp factor is $1\mathrm{.}0.$ The time of concentration $\backslash (\backslash$left$($t$\_\{$c$\}\backslash$right$)\backslash )$ calculated in the previous problem will be used here. Need to find runoff based on the NRCS method and $\backslash ($ q$\_\{$u$\}\backslash )($the unit peak discharge$)$ for the rainfall distribution type from the graph for $\backslash ($ t$\_\{$c$\}\backslash )$ in hours and $\backslash ($ I$\_\{$a$\}/$ P $\backslash ).$ Find the peak discharge for pre$-$ and post$-$development scenarios, the area must be in square miles.
