Plot IDF curves for Ozaukee County, WI$,$ using the document provided by the Southeastern Wisconsin Regional Planning Commission $($SEWRPC$).$ The document contains point precipitation frequency information derived from NOAA's Atlas $14,$ for the seven counties in the region. Use duration in minutes as abscissa $($log$-$scale, up to $4$ days$),$ intensity in inches per hour as ordinate $($log$-$scale$),$ and for return period $=2,10$ and $100$ years.

Plot IDF curves using the equations developed by SEWRPC with the model $i=\frac{a}{D^k+b},$ and compare them with part $1.$

Determine the intensity $($inches per hour$)$ for $10$year, $45$ minutes and $90$ minutes durations, using the curves you created in part $1,$ and use the equations in part$2.$
