Description

Input is a vector of mean daily flows. Output is a value that is the RB Flashiness Index

Usage

Arguments

`Q`	Vector of mean daily stream flows.

Details

The index is valid over the time period of the data. For example, if the vector contains a month's or a year's data the index will represent that time period. The index will be in the same units as the input data. The function assumes all days are represented (insert NA for missing values).
