Problem $1$:

The incremental rainfall data in the table were recorded in a $2-$acre dirt lot. Be careful to use a $0\mathrm{.}5-$

$hr$ time step and record intensity in $c\frac{m}{h}r.$

a$)$ Determine the rainfall intensity at each time step from the rainfall gage data below and

create a hyetograph of the storm event. What is the maximum rainfall intensity?

b$)$ Plot the rainfall hyetograph.

c$)$ Determine the total storm rainfall depth in inches.

d$)$ If the runoff coefficient is $0\mathrm{.}70,$ determine the runoff volume.
