eflowcalc.dh10(flows, datetimes, hydro_years, drainage_area)

Variability in annual maximum of 90-day daily flow.

Calculation Details

Compute the 90-day rolling mean flows. Take the maximum of these rolling means for each hydrological year. Calculate the standard deviation and the mean of these maximum values. Multiply the former by 100 and divide the result by the latter.
