Description
This function accepts a data frame that contains a column
named "discharge" and a threshold value obtained using
the peakdata and peakthresh functions and calculates
DH23; Flood duration. Compute the flood threshold as the
flow equivalent for a flood recurrence of 1.67 years.
Determine the number of days each year that the flow
remains above the flood threshold. DH23 is the mean (or
median-Use Preference option) of the number of flood days
for years in which floods occur (days-temporal).
Usage
1
dh23(qfiletempf, thresh)
Arguments
qfiletempf
data frame containing a "discharge"
column containing daily flow values
thresh
numeric containing 1.67-year flood
threshold calculated by getPeakThresh
Value
dh23 list containing DH23 for the given data frame
Examples
1
2
qfiletempf<-sampleData
dh23(qfiletempf, 1158)
