POR_apply_annual_lowflow_stats {HyMETT}

Calculate 10-year and 2-year return periods of a streamflow time series

Description

Calculates 10-year and 2-year return periods of a streamflow time series from annual n-day low streamflow values and returns a data.frame in the format of other period-of-record (POR) metrics.

Usage

POR_apply_annual_lowflow_stats(annual_min)

Arguments

annual_min

'numeric' vector or data.frame. Vector or data.frame with columns of annual n-day minimum streamflows.

Details

POR_apply_POR_lowflow_metrics is a helper function that applies the POR_calc_lp3_quantile function to the data.frame of n-day moving averages, which can be computed during pre-processing step using preproc_precondition_data and calc_annual_flow_stats, or preproc_main for both observed and modeled data. This function returns a data.frame with the 10-year and 2-year return period streamflows for each n-day low streamflow in the input data.frame.

Value

data.frame with 10-year and 2-year return period of n-day streamflows.
