Description

This function accepts a data frame that contains a column named "discharge" and calculates FL1; Low flood pulse count. Compute the average number of flow events with flows below a threshold equal to the 25th percentile value for the entire flow record. FL1 is the average (or median-Use Preference option) number of events (number of events/year-temporal). and FL2; Variability in low pulse count. Compute the standard deviation in the annual pulse counts for FL1. FL2 is 100 times the standard deviation divided by the mean pulse count (percent-spatial).
