Problem $5\mathrm{.}55$

A $\backslash (5-\backslash$mathrm$\{$mi$\}^\{2\}\backslash )$ watershed has a time of concentration of $6$ hours and land use$/$soil that yields a CN of $94.$ Compute the $\backslash (2-,5-,10-,25-,50\backslash )-,$ and $100-$year peak discharges using the NRCS Graphical method. Assume that Figure $2\mathrm{.}4$ is applicable. Also, estimate the extreme maximum discharge from the envelope curve of Equation $5\mathrm{.}52,$ region $4.$ What are the implications of these results in relationship to assigning an exceedance probability to extreme flood peaks?
