Arguments

InputsModel

Param

[numeric] vector of 7 (or 9 parameters if IsHyst = TRUE, see CreateRunOptions for details)

GR5H X1	production store capacity [mm]

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

The choice of the CemaNeige version is explained in CreateRunOptions.
For further details on the model, see the references section.
