tq_periods: Compute temperature-streamflow regime cycle periods

In IvanHeriver/hsa-R-package: Hydrological Signature Analysis toolbox

Description

Compute list containing the indices of each periods necessary to compute the slopes from the T-Q regime cycle:

• T+Q+ (TpQp) period

• T+Q- (TpQm) period

• T-Q-1 (TmQm1) period

• T-Q-2 (TmQm2) period

Usage

tq_periods(T, Q, periods = c(183, 336, 62))

Arguments

T	numeric vector. air temperature regime (365 or 366 values)
Q	numeric vector. streamflow regime (365 or 366 values)
peridos	numeric vector. a vector of length 3 defining (1) the start of the T+Q+ period, (2) the start (resp. end) of the T-Q-2 (resp. T-Q-1) period and (3) the end of the T-Q-2 period. Note: the other period boundaries are computed using the air temperature and streamflow regime maxima timings.

Value

A list containing the indices of the different periods in 4 components: "TpQp", "TpQm", "TmQm1", "TmQm2"
