Rainfall Intensity, Precipitation and Intensity$-$Duration$-$Frequency $($IDF$)$ Curves:

For a given location in Puerto Rico the NOAA Atlas $14$ Vol. $3$ Version $4$ provide the precipitation $-$

duration $-$ frequency values $($partial duration scries$)$ which are presented in the first table.

Determine $($completing the tables and showing all required computations and procedures$)$:

a$.$ Corresponding annual maxima rainfall intensities for the recurrence shown in the second table.

b$.$ For the recurrence $($Irequency$)$ indicated in the third table, use the values of the PDF table to obtain

the precipitation depth, rainfall intensity and finally the estimated surface runoff depth using a

simplified water cycle analysis if the evapotranspiration, infiltration depth and depression storage

are already given here or required to be computed $($as indicated$).$ Pasture $($and use

Recurrence, $(yr)=5$ years $($Part a$)$

Recurrence, $)=50$ years $($Part b$)$
