ta3: Function to return the TA3 hydrologic indicator statistic for...

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 threshold value obtained using the peakdata and peakthresh functions and calculates TA3; Seasonal predictability of flooding. Divide years up into 2-month periods (that is, Oct-Nov, Dec-Jan, and so forth). Count the number of flood days (flow events with flows > 1.67-year flood) in each period over the entire flow record. TA3 is the maximum number of flood days in any one period divided by the total number of flood days (dimensionless-temporal).

Usage

  ta3(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

ta3 numeric containing TA3 for the given data frame

Examples

qfiletempf<-sampleData
ta3(qfiletempf, 1158)
