dh15.16: Function to return the DH15 and DH16 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 DH15; High flow pulse duration. Compute the average duration for flow events with flows above a threshold equal to the 75th percentile value for each year in the flow record. DH15 is the median of the yearly average durations (days/year-temporal). and DH16; Variability in high flow pulse duration. Compute the standard deviation for the yearly average high pulse durations. DH16 is 100 times the standard deviation divided by the mean of the yearly average high pulse durations (percent-spatial).

Usage

  dh15.16(qfiletempf)

Arguments

qfiletempf

data frame containing a "discharge" column containing daily flow values

Value

dh15.16 list containing DH15 and DH16 for the given data frame

Examples

qfiletempf<-sampleData
dh15.16(qfiletempf)
