tsEvaNanRunnigBlowTh {RtsEva}

Calculate the return period of low flow based on a threshold and window size

Description

This function calculates the return period of low flow for a given time series based on a threshold and window size. It uses a sliding window approach to count the number of values below the threshold within each window, and then calculates the return period based on the proportion of values below the threshold. Assumes that the input data has a 7 days timestep.

Usage

tsEvaNanRunnigBlowTh(series, threshold, windowSize)

Arguments

series

The time series data.

threshold

The threshold value for low flow.

windowSize

The size of the sliding window.

Value

A data frame with two columns: "time" representing the time points corresponding to the sliding windows, and "RP" representing the calculated return period of low flow.

Examples

series <- c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
threshold <- 5
windowSize <- 3
tsEvaNanRunnigBlowTh(series, threshold, windowSize)
