rmf_create_hob: Create an 'RMODFLOW' hob object

In rogiersbart/RMODFLOW: Pre- and post-processing of MODFLOW files

Create an RMODFLOW hob object

Description

rmf_create_hob creates an RMODFLOW hob object

Usage

rmf_create_hob(
  locations,
  time_series,
  dis,
  hydraulic_conductivity = array(1, dim = c(dis$nrow, dis$ncol, dis$nlay)),
  prj = rmf_get_prj(dis),
  iuhobsv = 665,
  hobdry = -888,
  noprint = FALSE,
  tomulth = 1,
  itt = 1,
  unique_obsnam = FALSE
)

Arguments

locations	data.frame or sf POINT object with the name, x and y coordinates (if data.frame), and top and bottom of the monitoring well filter
time_series	data.frame with the name of the monitoring well filter and the observation time and head
dis	RMODFLOW dis object
hydraulic_conductivity	3d array with hydraulic conductivity values, for calculating the weights for a multilayer observations
prj	RMODFLOW prj object; provide if coordinates in locations are real world coordinates
iuhobsv	file unit (> 0) for saving observation data in a file; the file unit should be included as DATA type in the name file; defaults to 665
hobdry	value of the simulated equivalent for a dry cell used in the observation output file
noprint	logical; if TRUE, the input and output are not printed in the listing file
itt	integer flag, either a single value or a value for every observation well as defined in locations. Identifies whether hydraulic heads (1; default) or changes in hydraulic heads (2) are used as observations. See details.
unique_obsnam	logical; should an ID number be added to obsnam for filters with observations at different times prefixed with an underscore? Defaults to FALSE.
tomult	time offset multiplier, to convert the time unit in time_series to the MODFLOW time unit

Details

Regardless of the value of itt, observed heads should be specified in time_series. MODFLOW will calculate the changes in hydraulic head internally. The locations data.frame must have columns named name, x, y, top, bottom. The time_series data.frame must have columns named name, time, head.

Value

Object of class hob
