Route the runoff hydrograph shown in Table $1$ through a detention having the stage$-$area characteristics shown in Table $2.$ Use the conic method to generate storage values. The outflow structure consists of a low flow device that consists of a $24-$inch circular orifice having a discharge coefficient of $C_d=0\mathrm{.}62.$ The emergency spillway consists of a $5ft$ rectangular weir with a weir coefficient of $C_w=2\mathrm{.}8.$ The crest of the emergency spillway is at elevation $503\mathrm{.}0.$ The pond is a dry pond. Use the Contech Hydraulic Tools program to verify your solution.
