Question
A double-mass curve is a graph of the
cumulative catch at the rain gage of
interest versus the cumulative catch of
one or more gages in the regions that
have been subjected to similar
meteorological occurrences and are
known to be consistent.
The annual rainfalls of gage A,B, C and
D are given in table below. Gage D was
permanently relocated after a period of
3 years (at the end of 1988). Adjust the
recorded values from 1986 through
1988 of gage D using double mass
curve with the assumption that the
other gages are consistent.
Give your answers for the adjusted
data in order (1986, 1987, 1988). Give
your answers rounded off to the
nearest hundredths.
Submit your solution and the double -
mass curve for both on the folder
provided.
