The amplitude (AMP, unit: \(m^3/s\)) of an event is defined as
the difference between the flow maximum (\(Q_{max}\)) and the
flow minimum (\(Q_{min}\)).
Given an event with equal flow trend, the amplitude is computed and returned.
Usage
amp(x)
Value
Returns a positive numeric value which is the difference of
max(x$Q) and min(x$Q) of an event. If a data frame containing
NA flow rates (Q) is given, NA is returned.
Arguments
x
Data frame (time series) from an event with equal flow trend. The
data frame must contain a date-time column (Time) and a flow rate
column (Q) and must be in a compatible format
(see flow()).
