Directions. for Application:
1) From precipitation maps determine 6 hr. and
24 hr. amounts for the selected frequency.
These maps are printed in the County Hydrology
Manual (10. 50 and 100 yr, maps included in the
Design and Procedure Manual), ;
2) Adjust 6 hr, precipitation (if necessary) so
that it is within the range of 45% to 65% of
the 24 hr, precipitation. (Not applicable
to Desert)
3) Plot 6 hr, precipitation- on the right side
of the chart,
4) Draw a line through the point parallel to the
plotted lines,
5) This line is the intensity-duration curve for
the location being analyzed,
Application term:
0) Selected Frequency /00 yr,
