Calibration of the parameters of one catchment or a network of sub-catchments — Calibration.GRiwrmInputsModel • airGRiwrm

Calibration algorithm that optimizes the error criterion selected as objective function using the provided functions.

# S3 method for GRiwrmInputsModel
Calibration(
  InputsModel,
  RunOptions,
  InputsCrit,
  CalibOptions,
  useUpstreamQsim = TRUE,
  ...
)

# S3 method for InputsModel
Calibration(InputsModel, ...)

Calibration(InputsModel, ...)

Arguments

InputsModel: [object of class InputsModel or GRiwrmInputsModel] see CreateInputsModel
RunOptions: [object of class RunOptions or GRiwrmRunOptions] see CreateRunOptions
InputsCrit: [object of class InputsCrit or GRiwrmInputsCrit] see CreateInputsCrit
CalibOptions: [object of class CalibOptions or GRiwrmCalibOptions] see CreateCalibOptions for details
useUpstreamQsim: boolean describing if simulated (TRUE) or observed (FALSE) flows are used for calibration. Default is TRUE
...: further arguments passed to airGR::Calibration, see details

Value

Depending on the class of InputsModel argument (respectively InputsModel and GRiwrmInputsModel object), the returned value is respectively:

a InputsCrit object (See airGR::CreateInputsCrit)
a GRiwrmInputsCrit object which is a list of InputsCrit objects with one item per modeled sub-catchment

Details

This function can be used either for a catchment (with an InputsModel object) or for a network (with a GRiwrmInputsModel object)

Argument classes should be consistent to the usage:

a InputsModel argument of class InputsModel must be followed by a RunOptions argument of class RunOptions, a InputsCrit argument of class InputsCrit and a CalibOptions of class CalibOptions
- a InputsModel argument of class GRiwrmInputsModel must be followed by a RunOptions argument of class GRiwrmRunOptions, a InputsCrit argument of class GRiwrmInputsCrit and a CalibOptions of class GRiwrmCalibOptions
