$(15$ points$)$ The Clean River drains a watershed that has an area of $14\mathrm{.}4k{m}^2.$ A storm event over the watershed was capable of producing runoff. The DRH measured at the Clean River is given below. Use this information to solve the following:

a$.(4)$ Calculate the total volume of runoff generated during the storm.

b$.(4)$ Calculate the peak runoff $($flow$)$ resulting from the storm.

c$.(4)$ Can this DRH be considered a Unit Hydrograph? Why or why not? Show calculations.

d$.(3)$ Calculate the baseflow for the time period of $15-16$ hr$.$
