Description

This function accepts a data frame that contains a column named "discharge" and a threshold value calculated for the site using the peakdata and peakthresh functions and calculates FH11; Flood frequency. Compute the average number of flow events with flows above a threshold equal to flow corresponding to a 1.67-year recurrence interval. FH11 is the average (or median-Use Preference option) number of events (number of events/year-temporal).

Usage

thresh

numeric containing 1.67-year flood threshold calculated by getPeakThresh

pref

string containing a "mean" or "median" preference

Value
