annualfreqplot: Plots the frequency curve and calculates the return periods

In valeriyafilipova/StochasticPQRUT: Functions for Stochastic PQRUT

Description

Plots the frequency curve and calculates the return periods

Usage

annualfreqplot(pathmain = NULL, qtT, Nsim, durt, qobs, Qsim, Pint, nsy,
  incond, plotpos = "Gringorten", writeResults = TRUE, PDFplots = TRUE)

Arguments

pathmain	path to files, not needed if writeResults=FALSE
qtT	threshold quantile for POT (Peak over threshold) events
Nsim	number of simulations
durt	critical duration
qobs	observed streamflow data; dataframe with columns Date ("%Y-%m-%d %H:%M:%S") and Q, if writeResults=TRUE path to csv file with columns date and Q
Qsim	dataframe of simulated streamflow and snowmel data (otput from the function hydrolsim) , not needed if writeResults=TRUE
Pint	dataframe of simulated precipitation values (daily values)
nsy	dataframe of extracted POT rain events for each season
incond	dataframe of initial conditions (soil moisture deficit, Qin and SWE) for each season
plotpos	te formula which is used for the pplotting positions, possible choices are only Gringorten and Weibull

Value

csv file with return periods
