RunModel_CemaNeigeGR4H: Run with the CemaNeigeGR4H hydrological model

In airGR: Suite of GR Hydrological Models for Precipitation-Runoff Modelling

Run with the CemaNeigeGR4H hydrological model

Description

Function which performs a single run for the CemaNeige-GR4H hourly lumped model over the test period.

Usage

RunModel_CemaNeigeGR4H(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 6 (or 8 parameters if IsHyst = TRUE, see CreateRunOptions for details) GR4H X1 production store capacity [mm] GR4H X2 intercatchment exchange coefficient [mm/h] GR4H X3 routing store capacity [mm] GR4H X4 unit hydrograph time constant [h] CemaNeige X1 weighting coefficient for snow pack thermal state [-] CemaNeige X2 degree-hour melt coefficient [mm/°C/h] CemaNeige X3 (optional) accumulation threshold [mm] (needed if IsHyst = TRUE) CemaNeige X4 (optional) percentage (between 0 and 1) of annual snowfall defining the melt threshold [-] (needed if IsHyst = TRUE)

Details

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

The choice of the CemaNeige version is explained in 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_GR4J to look at the diagram of the hydrological model.
