Provides wrapper to turn the hy_sed_samples_psd table in HYDAT into a tidy data frame of instantaneous sediment sample
particle size distribution. station_number
and prov_terr_state_loc
can both be supplied. If both
are omitted all values from the hy_stations
table are returned. That is a large vector for hy_sed_samples_psd
.
hy_sed_samples_psd(
station_number = NULL,
hydat_path = NULL,
prov_terr_state_loc = NULL,
start_date = NULL,
end_date = NULL
)
A seven digit Water Survey of Canada station number. If this argument is omitted, the value of prov_terr_state_loc
is returned.
The path to the hydat database or NULL to use the default location used by download_hydat. It is also possible to pass in an existing src_sqlite such that the database only needs to be opened once per user-level call.
Province, state or territory. If this argument is omitted, the value of station_number
is returned. See unique(allstations$prov_terr_state_loc)
. Will also accept CA
to return only Canadian stations.
Leave blank if all dates are required. Date format needs to be in YYYY-MM-DD. Date is inclusive.

A tibble of sediment sample particle size data
A tibble with 5 variables:
Unique 7 digit Water Survey of Canada station number
Contains the type of sampling method used in collecting sediment for a station
Contains the time to the nearest minute of when the sample was taken
Particle size (mm)
Contains the percentage values for indicated particle sizes for samples collected
