Read a MODFLOW-NWT Upstream Weighting file — rmf_read

rmf_read_upw reads in a MODFLOW-NWT upstream weighting file and returns it as an RMODFLOW upw object.

rmf_read_upw(
  file = {     cat("Please select upw file ...\n")     file.choose() },
  dis = {     cat("Please select corresponding dis file ...\n")    
    rmf_read_dis(file.choose()) },
  mlt = NULL,
  zon = NULL,
  ...
)

Arguments

file	filename; typically '*.upw'
dis	an `RMODFLOW` dis object
mlt	a `RMODFLOW` mlt object. Only needed when reading parameter arrays defined by multiplier arrays
zon	a `RMODFLOW` zon object. Only needed when reading parameter arrays defined by zone arrays
...	arguments passed to `rmfi_parse_array`. Can be ignored when input arrays are 'free' format and INTERNAL or CONSTANT.

Value

object of class upw

Note

upw input structure is nearly identical to lpf but calculations are done differently. Differences include the addition of the iphdry value and the ommision of optional keywords. Layer wetting capabilities are also not supported by upw.

upw must be used with the Newton solver. See also rmf_create_nwt.
