Concise description:

Derived from time series of observed or simulated hydrometeorological variables using a pre-defined threshold level.When the variable is below this level, the site is in drought. Drought duration, severity, and frequency can easily be calculated. Thresholds are often derived from percentiles of the flow duration curve, commonly ranging between the 70th and 95th percentile for perennial rivers.
