The table below lists rainfall data recorded at a USGS gage for a given storm. The watershed area is

$2050$ acres. Using these data, develop a rainfall hyetograph in $15-$min intervals and determine the time

period with the highest intensity rainfall. In addition, plot the cumulative mass curve for the rainfall.

$($in ac$-$ft$)$ for this storm if evapotranspiration can be neglected? What is the runoff coefficient for this

storm? $($Assume that $1$ cfs$-$hr ~ $1$ ac$-$in
