In joshualerickson/whitewater: Parallel Processing Options for Package 'dataRetrieval'

Process USGS daily values

Description

This function is a wrapper around readNWISdv but includes added variables like water year, lat/lon, station name, altitude and tidied dates.

Usage

ww_dvUSGS(
  sites,
  parameter_cd = "00060",
  start_date = "",
  end_date = "",
  stat_cd = "00003",
  parallel = FALSE,
  wy_month = 10,
  verbose = TRUE,
  ...
)

Arguments

sites	A vector of USGS NWIS sites
parameter_cd	A USGS code for metric, default is "00060".
start_date	A character of date format, e.g. "1990-09-01"
end_date	A character of date format, e.g. "1990-09-01"
stat_cd	character USGS statistic code. This is usually 5 digits. Daily mean (00003) is the default.
parallel	logical indicating whether to use future_map().
wy_month	numeric indicating the start month of the water year. e.g. 10 (default).
verbose	logical for printing information. TRUE (default).
...	arguments to pass on to future_map.

Value

A tibble with daily metrics and added meta-data.

Note

Use it the same way you would use readNWISdv.

Examples

## Not run: 

library(whitewater)
yaak_river_dv <- ww_dvUSGS('12304500',
parameter_cd = '00060',
wy_month = 10)

#parallel

#get sites

huc17_sites <- dataRetrieval::whatNWISdata(huc = 17,
siteStatus = 'active',
service = 'dv',
parameterCd = '00060')

library(future)
#need to call future::plan()
plan(multisession(workers = availableCores()-1))

pnw_dv <- ww_dvUSGS(huc17_sites$site_no,
parameter_cd = '00060',
wy_month = 10,
parallel = TRUE)
