Description

Function which performs a single run for the GR5H hourly lumped model.

Usage

1
RunModel_GR5H(InputsModel, RunOptions, Param)

Arguments

InputsModel

[object of class InputsModel] see CreateInputsModel for details

RunOptions

[object of class RunOptions] see CreateRunOptions for details

Param

[numeric] vector of 5 parameters

GR5H X1 production store capacity [mm]
GR5H X2 intercatchment exchange coefficient [mm/h]
GR5H X3 routing store capacity [mm]
GR5H X4 unit hydrograph time constant [h]
GR5H X5 intercatchment exchange threshold [-]

Details

It is advised to run the GR5H model with an interception store (see Ficchi (2017) and Ficchi et al. (2019)) as it improves the consistency of the model fluxes and provides better performance. To do so, the Imax function allows to estimate the maximal capacity of the interception store, which can then be given to CreateRunOptions.

For further details on the model, see the references section.
For further details on the argument structures and initialisation options, see CreateRunOptions.

See RunModel_GR5J to look at the diagram of the hydrological model when no interception store is used.
