Problem $2$:

During a $45-$minute storm, the precipitation rate over a $77-$acre area is $0\mathrm{.}55$ in$/$hr$.$ An infiltration

rate of $0\mathrm{.}14$ in$/$hr is assessed for the period of the storm. The average river outflow from the area

is $28$ cfs during the storm. What is the value of combined depression and interception storages in

acre$-$ft$,$ cubic ft$,$ and cfs$-$hour? $[10]$

Hint: Remember the river outflow is equal to the runoff. Apply the mass conservation for the

precipitation that is P $=$ R $+$ I $+$ SI $+$ SDep to fine the combined value for depression and interception

storages.
