fh1.2: Function to return the FH1 and FH2 hydrologic indicator...

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 calculates FH1; High flood pulse count. Compute the average number of flow events with flows above a threshold equal to the 75th percentile value for the entire flow record. FH1 is the average (or median-Use Preference option) number of events (number of events/year-temporal). FH2; Variability in high pulse count. Compute the standard deviation in the annual pulse counts for FH1. FH2 is 100 times the standard deviation divided by the mean pulse count (number of events/year-spatial).

Usage

  fh1.2(qfiletempf, pref = "mean")

Arguments

qfiletempf	data frame containing a "discharge" column containing daily flow values
pref	string containing a "mean" or "median" preference

Value

fh1.2 list of FH1 and FH2 for the given data frame

Examples

qfiletempf<-sampleData
fh1.2(qfiletempf)
