Description
This function accepts a data frame that contains columns
named "discharge" and "year_val" and calculates the
skewness in annual maximum flows (dimensionless-spatial).
Use the equation: MH19 numerator = N2 ? sum(qm3)-3N ?
sum(qm) ? sum(qm2) + 2 ? (sum(qm))3 denominator = N ?
(N-1) ? (N-2) ? stddev3 Where: N = Number of years qm =
Log10 (annual maximum flows) stddev = Standard deviation
of the annual maximum flows
Usage
1
mh19(x)
Arguments
x
data frame containing a "discharge" column
containing daily flow values
Value
mh19 numeric value of MH19 for the given data frame
