fl1.2: Function to return the FL1 and FL2 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 FL1; Low flood pulse count. Compute the average number of flow events with flows below a threshold equal to the 25th percentile value for the entire flow record. FL1 is the average (or median-Use Preference option) number of events (number of events/year-temporal). and FL2; Variability in low pulse count. Compute the standard deviation in the annual pulse counts for FL1. FL2 is 100 times the standard deviation divided by the mean pulse count (percent-spatial).

Usage

  fl1.2(qfiletempf, pref = "mean")

Arguments

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

Value

fl1.2 list of FL1 and FL2 for the given data frame

Examples

qfiletempf<-sampleData
fl1.2(qfiletempf)
