loadTabularData: Load Tabular Hydro-Meteorological Data

In hydrosolutions/riversCentralAsia: Accompanying R Package to Applied Modeling of Hydrological Systems in Central Asia Course

Load Tabular Hydro-Meteorological Data

Description

Loads csv files with tabular hydrometeorological data where years are in rows and decades or months are in columns. The function automatically detects if monthly or decadal (10-day) data is provided. The function automatically computes the long-term norm of the data provided and returns a time aware tibble with date, data, data norm columns and code columns.

Usage

loadTabularData(
  fPath,
  fName,
  code,
  stationName,
  rName,
  rBasin,
  dataType,
  units
)

Arguments

fPath	Path to the input file
fName	File name (.csv file as input required)
code	Hydrometeorological station code
stationName	Hydrometeorological station name/location
rName	Name of river
rBasin	Name of basin
dataType	Type of data, either 'Q' (discharge data), 'T' (temperature data) or 'P' (precipitation data)
units	Data units

Details

Note that the input file needs to be in coma-separated format and without header.

The most common format for hydrological data in Central Asia is in tabular form with the years in rows and the months or decades in columns, i.e. the data has 13 columns and as many rows as years of data. An input file containing monthly data might look like follows:
1990,0.1,0.1,0.2,0.2,0.3,0.3,0.4,0.4,0.3,0.2,0.1,0.1
1991,0.1,0.1,0.2,0.2,0.3,0.3,0.4,0.4,0.3,0.2,0.1,0.1
1992,0.1,0.1,0.2,0.2,0.3,0.3,0.4,0.4,0.3,0.2,0.1,0.1
...
An input file containing decadal data (every 10 days) would have 37 columns, the first for the year and the following for each decade in a year.

Value

Time-aware tibble with relevant data
