Question
A double mass curve was plotted for a station. The curve shows a change in slope at
year 1990 where the slope before was 0.68, after that year the difference in two
successive cumulative of average precipitation of 10 surrounding stations was 4950
and the corresponding difference in cumulative annual precipitation was 4300. If the
rainfall data for this station were as in the table below then adjust (correct) the rainfall
data of this station:
Year
1989
1990
1991
1992
Original rainfall (mm)
550
475
410
350
