RunModel(x, RunOptions, Param, ...)

Arguments

x

[object of class GRiwrmInputsModel] see CreateInputsModel.GRiwrm for details

RunOptions

[object of class GRiwrmRunOptions] see CreateRunOptions.GRiwrmInputsModel for details

Param

list parameter values. The list item names are the IDs of the sub-basins. Each item is a numeric vector

...

Further arguments for compatibility with S3 methods

Value

An object of class GRiwrmOutputsModel. This object is a list of OutputsModel objects produced by RunModel.InputsModel for each node of the semi-distributed model.

It also contains the following attributes (see attr):

  • "Qm3s": a data.frame containing the dates of simulation and one column by node with the simulated flows in cubic meters per seconds (See plot.Qm3s)

  • "GRiwrm": a copy of the GRiwrm object produced by CreateGRiwrm and used for the simulation

  • "TimeStep": time step of the simulation in seconds
