Obtains a single model parameter or all model parameters at once.
# S4 method for RPhosFate
getParameter(x, parameter = NULL)Depends on the queried parameter or a list in case of all
parameters. See model parameter arguments section for further information.
An S4 RPhosFate river catchment object.
A character string specifying a parameter name or NULL for
a list of all parameters. See model parameter arguments section for
further information.
ns_slp_min: A numeric scalar specifying the minimum bounding slope in %
(defaults to 1.0).
ns_slp_max: A numeric scalar specifying the maximum bounding slope in %
(defaults to 999.0).
ns_rhy_a: A numeric scalar specifying a network constant depending on the
discharge frequency needed for the calculation of the hydraulic radius, which
in turn is a prerequisite for substance transport (defaults to 0.09
representing a discharge frequency of approximately six years).
ns_rhy_b: A numeric scalar specifying a geometry scaling exponent
depending on the discharge frequency needed for the calculation of the
hydraulic radius, which in turn is a prerequisite for substance transport
(defaults to 0.50 representing a discharge frequency of approximately six
years).
ns_cha_rto: A numeric scalar specifying the ratio of the channel to the
cell width determining the widths of the riparian zones required for
substance transport (defaults to 0.5).
ns_man_rip: A numeric scalar specifying Manning's roughness coefficient
of the riparian zones within channel cells required for substance
transport (defaults to 0.32).
ns_man_cha: A numeric scalar specifying Manning's roughness coefficient
of the channel within channel cells required for substance transport
(defaults to 0.04).
ns_dep_ovl: A numeric scalar specifying the overland deposition rate per
second required for substance transport (calibration parameter; no
default).
ns_dep_cha: A numeric scalar specifying the channel deposition rate per
second required for substance transport (calibration parameter; no
default).
nv_tfc_inl: A named numeric vector specifying the inlet transfer
coefficients required for substance transport, for example, c(SS = 0.6, PP = 0.6) (no default).
nv_enr_rto A named numeric vector specifying the substance enrichment
ratios required for substance except SS transport, for example, c(PP = 2.0) (calibration parameter; no default).
nm_olc: A two column numeric matrix specifying one or more catchment
outlet coordinates required for the in-channel retention ratio of
calibrationQuality (no default).
df_cdt: A data.frame with calibration data, which must have at least
the following three columns and one or more columns with substance river
loads in t/yr (no default):
ID: ID(s) of the gauge(s)
x: x-coordinate(s) of the gauge(s)
y: y-coordinate(s) of the gauge(s)
