In hydrotoolbox: Hydrological Tools for Handling Hydro-Meteorological Data Records

Monthly river discharge [m3/s] to volume [hm3]

Description

Converts mean monthly river discharge [m3/s] to total volume discharge [hm3].

Usage

qm_vol(x, col_name, out_name = NULL)

Arguments

x	data frame with class Date in the first column and numeric on the others.
col_name	string with column(s) name(s) where to apply the function.
out_name	optional. String with new column(s) name(s). If you set it as NULL, the function will overwrite the original data frame.

Value

The same data frame but with the total volume discharge.

Examples

# read guido daily streamflow records
path <- system.file('extdata', 'snih_qd_guido.xlsx',
        package = 'hydrotoolbox')

# read, aggregate the function to monthly resolution and get the volume
qm_guido <-
  read_snih(path = path, by = 'day', out_name = 'q(m3/s)') %>%
  agg_table(col_name = 'q(m3/s)', fun = 'mean', period = 'monthly',
            out_name = 'qm(m3/s)') %>%
  qm_vol(col_name = 'qm(m3/s)', out_name = 'vm(hm3)')
