Problem $2\mathrm{.}2$

Using the rainfall summary for Washington, D$.$C$.,$ for September $1983($Table $2\mathrm{.}1),$

graph the hourly hyetograph $(in\frac{.}{h}r)$ for the storm of September $30.$ Determine the

total depth $($in$.).$ Also, determine the peak hourly rate $($in$./$ hr$)$ and the maximum $3-$hour

rate of rainfall for the storm. What volume of rain $($in acre$-$ ft $)$ would fall on a $50-$acre

watershed for this storm event?
