PRSim (version 1.5)

simulations_multi_sites: Simulated runoff for four catchments

Description

The dataset is generated with the package own routines and represent 5 series of 38 years of runoff for four catchments

Usage

data("simulations_multi_sites")

Format

A list of four elements (one per catchment), containing a data frame each holding information about the observed time series and the stochastic simulations

YYYY

a numeric vector, year

MM

a numeric vector, month

DD

a numeric vector, day

timestamp

POSIXct vector of the daily runoff

Qobs

observed runoff

r1,...,r5

5 simulated runoff series

Details

The data is included to illustrate the validation and visualization routines in demo("PRSim_wave-validate").
