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 TH3; Seasonal predictability of nonflooding. Computed as the maximum proportion of a 365-day year that the flow is less than the 1.67-year flood threshold and also occurs in all years. Accumulate nonflood days that span all years. TH3 is maximum length of those flood-free periods divided by 365 (dimensionless-spatial).
