Arguments

df

A data.table with date and Q columns

gap_max

Default 5 days.

• gaps (in days) <= gap_max is regarded as the same event.

• gaps > gap_max, it will be regarded as two events.

extend

Default ddays(5). Extend nday in the left and right of a event

Q_min

minimum discharge to detect flood events

Q_peak

peak discharge to detect flood events
