extract_pot_allstations: Extracting POT-values for a set of stations

In NVE/NVEHYDROTOOLS: Set of R functions for hydrological analysis at NVE

Description

Use independence criterion based on Lang et al (1999)

See 'get_pot' for deitals on how independent POT values are extracted

Should first extract AMS values to get the years to be used for extracting POT data

Usage

  extract_pot_allstations(amsfile = "inst/Example_data/Flooddata/amsvalues.txt",
  dailydata = "inst/Example_data/Dailydata", p_threshold = 0.98, TSEP = 6,
  pratio = 2/3, outfile = "inst/Example_data/Flooddata/potvalues.txt")

Arguments

amsfile	file with annual maximum data. Only years with ams will be used
dailydata	folder with daily data
p_threshold	the thershold for selecting flood values given as emprical quantile of all data
pratio	The minimum flow between two flood peaks should be less than pratio times the first flood peak.
outfile	The file for storing ams values
TTR_3X	The minimum time between two independent flood peaks

Value

data frame with reginenumber, main number, flood date, flod size, thershold. for all stations. The dataframe is written to the specified outfile.

Examples

extract_pot_allstations(amsfile='inst/Example_data/Flooddata/amsvalues.txt',
dailydata="inst/Example_data/Dailydata",
p_threshold = 0.98, TSEP = 6,pratio= 2.0/3.0,
outfile="inst/Example_data/Flooddata/potvalues.txt")
