Variability in base flow 1.

Calculation Details

Compute the 7-day rolling mean flows for each hydrological year, take the minimum rolling mean value, and divide this minimum by the mean flow for the whole daily record to obtain the base flow index for the hydrological year. Compute the standard deviation and the mean of the base flow indices. Multiply the former by 100 and divide the result by the latter.
