Figure 3.6
is intended to show the diurnal comparison between the design storm and the two
storm events experienced during February of 2014. The comparison indicates that, based on the
balanced centered hyetograph
, the design storm’s peak hour value is at
0.78 inches per hour
(in/hr), while the February 26
th
and 28
th
storms peak values are 0.24 and 0.45 in/hr respectively.
This comparison illustrates the more conservative nature of the design storm and the relatively
small storm events experienced in February 2014.
