Description
This function accepts a data frame that contains a column
named "discharge" and a threshold value obtained using
the peakdata and getPeakThresh functions and calculates
TL4; Seasonal predictability of non-low flow. Compute the
number of days that flow is above the 5-year flood
threshold as the ratio of number of days to 365 or 366
(leap year) for each year. TL4 is the maximum of the
yearly ratios (dimensionless-spatial).
Usage
1
tl4(qfiletempf, thresh)
Arguments
qfiletempf
data frame containing a "discharge"
column containing daily flow values
thresh
value containing the 5-year recurrence
value for the site
Value
tl4 numeric containing TL4 for the given data frame
Examples
1
2
qfiletempf<-sampleData
tl4(qfiletempf, 1161.38)
