add_daily_volume

Add a daily volumetric flows column to daily flows

Description

Add a column of daily volumetric flows to a daily streamflow data set, in units of cubic metres. Converts the discharge to a volume.

Usage

add_daily_volume(data, values = Value, station_number)

Arguments

`data`	Data frame of daily data that contains columns of dates, flow values, and (optional) groups (e.g. station numbers). Leave blank if using `station_number` argument.
`values`	Name of column in `data` that contains numeric flow values, in units of cubic metres per second. Only required if values column name is not 'Value' (default). Leave blank if using `station_number` argument.
`station_number`	Character string vector of seven digit Water Survey of Canada station numbers (e.g. `"08NM116"`) of which to extract daily streamflow data from a HYDAT database. Requires `tidyhydat` package and a HYDAT database. Leave blank if using `data` argument.

Value

A tibble data frame of the source data with an additional column:

Volume_m3

daily total volumetric flow, in units of cubic metres

Examples

# Run if HYDAT database has been downloaded (using tidyhydat::download_hydat())
if (file.exists(tidyhydat::hy_downloaded_db())) {

# Add a column of daily flow volumes
add_daily_volume(station_number = "08NM116")

}
