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
DH22; Flood interval. Compute the flood threshold as the
flow equivalent for a flood recurrence of 1.67 years.
Determine the median number of days between flood events
for each year. DH22 is the mean (or median-Use Preference
option) of the yearly median number of days between flood
events (days-temporal).
Usage
1
dh22(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
dh22 numeric containing DH22 for the given data frame
Examples
1
2
qfiletempf<-sampleData
dh22(qfiletempf, 1158)
