fh11: Function to return the FH11 hydrologic indicator statistic...

In jlthomps/EflowStats: Returns HIT/HAT Hydrologic Indicator stats for a given set of data

Description

This function accepts a data frame that contains a column named "discharge" and a threshold value calculated for the site using the peakdata and peakthresh functions and calculates FH11; Flood frequency. Compute the average number of flow events with flows above a threshold equal to flow corresponding to a 1.67-year recurrence interval. FH11 is the average (or median-Use Preference option) number of events (number of events/year-temporal).

Usage

  fh11(qfiletempf, thresh, pref = "mean")

Arguments

qfiletempf	data frame containing a "discharge" column containing daily flow values
thresh	numeric containing 1.67-year flood threshold calculated by getPeakThresh
pref	string containing a "mean" or "median" preference

Value

fh11 numeric containing FH11 for the given data frame

Examples

qfiletempf<-sampleData
sites<-"02178400"
peakValues<-getPeakData(sites)
thresh<-1158.495
fh11(qfiletempf,thresh)
